> SIGMA incorporation note: This friend-reviewed analysis has been preserved as a project reference and converted into roadmap and task-matrix actions. Some original observations were written before the latest repository updates. Current SIGMA now has a rendered GitHub Pages site, Pagefind-compatible public search, active W3C, ITU, ETSI, OASIS, Ecma, GS1, and IEC priority standards slices, schema/release/Pages workflows, 20,140 generated relationship edges in relationships_extracted.csv, a project knowledge graph, and rendered roadmap/task documentation. The remaining recommendations are treated as prioritized enhancement work, not as a replacement for the source-of-truth research plan.

1. WHAT THE REPOSITORY CURRENTLY IS — FULL INVENTORY

Before diagnosing gaps, it is essential to state precisely what already exists. This is the honest, complete inventory based on direct observation.

1.2 Confirmed Data Volume

According to the README:

• 88,204 master entries generated in the Phase 8A national standards body slice
• 20,140 relationship edges generated
• All 40 canonical domains represented (at minimum with one entry each)
• Processed sources include: ISO metadata, IETF RFC metadata, ILO standards, Wikidata standards-body metadata, WHO/Sphere health priority records (Phase 2A), Codex food-safety records (Phase 2B), humanitarian standards (Phase 2C, partial), national standards bodies (Phase 8A)

1.3 Confirmed Python Dependencies (from pyproject.toml)

requests, beautifulsoup4, SPARQLWrapper, pandas, openpyxl, pyarrow

This confirms the pipeline can handle: HTTP scraping, HTML parsing, Wikidata SPARQL queries, data manipulation, Excel output, and Parquet output.

1.4 Confirmed Makefile Targets

The build system has 14 confirmed working targets: validate, relationships, research-tasks, quality-gate, health-priority, codex, humanitarian-priority, who-iris-stage, national-standards-bodies, release, site, sync-google-sheet, clean.

2. WHAT THE REPOSITORY HAS DONE WELL — GENUINE STRENGTHS

It is important to acknowledge what works before diagnosing problems. These are genuine achievements that put SIGMA well ahead of any comparable free project.

✅ Strength 1: Scale — 88,114 entries is extraordinary for a free, open project

No other freely available, open-source, unified standards index comes close to this number. The Wikidata standards corpus has fewer structured entries. Wikipedia's list of technical standard organizations covers only the bodies, not the standards themselves. This is a genuinely unprecedented scale for a CC BY 4.0 open dataset.

✅ Strength 2: The schema is correct and forward-looking

The 22-field schema is well-designed. It includes the critical fields that most standards databases omit: why_it_matters (plain-language significance), mandate (mandatory vs. voluntary — a field almost no index includes), sector_applicability, and data_source (provenance tracking). The supplementary tables for bodies, relationships, and ratification tracking show mature thinking about the full data model.

✅ Strength 3: The build pipeline is professional and reproducible

Having a Makefile with discrete targets for each phase, a pyproject.toml for proper Python packaging, and schema validation scripts means this is not a one-person artisanal project — it is a reproducible, forkable data engineering system. The sync-google-sheet target for bridging manual curation with automated processing is particularly clever.

✅ Strength 4: Multiple data sources already integrated

ISO Open Data (bulk), IETF RFC index, ILO NORMLEX (via API), WHO IRIS (OAI-PMH harvesting), Wikidata SPARQL, Codex Alimentarius, Sphere/CHS humanitarian standards, and national standards bodies — all integrated in a single pipeline. This cross-source integration is the core technical achievement of SIGMA.

✅ Strength 5: The governance documentation is solid

CC BY 4.0 license, CONTRIBUTING.md, CODE_OF_CONDUCT.md, SCHEMA.md, and the 97 KB Research Project Plan all exist. A new contributor can understand the project's scope, values, and how to add entries without needing to contact the maintainer.

✅ Strength 6: Relationship graph architecture exists

The relationships schema with confidence levels (source-confirmed, curator-reviewed, llm-suggested) and the distinction between confirmed and unconfirmed LLM-suggested edges is a responsible, production-quality design that most open data projects skip entirely.

3. THE 8 CATEGORIES OF GAPS — DETAILED ANALYSIS

This is the core diagnostic section. Each gap is described precisely, with its real-world consequence and what solving it would unlock.

---

GAP CATEGORY 3.1 — DATA QUALITY GAPS

These are the most urgent gaps. High entry count means little if the entries are thin.

Gap 3.1.A — why_it_matters is almost certainly empty for bulk-ingested entries

What is observed: The ISO metadata CSVs, IETF RFC index, and ILO NORMLEX data do not contain a why_it_matters field. Processing scripts that ingest these sources will produce rows with an empty or templated why_it_matters column for the overwhelming majority of entries.

Real-world consequence: The most valuable field in the entire schema — the one that makes SIGMA usable by a non-expert, a policymaker, a field worker, or a journalist — is empty for perhaps 80,000+ of the 88,114 entries. A user searching for ISO 45001 who finds an entry with no explanation of why it matters has gained nothing over searching iso.org directly.

What good looks like: Every entry, at minimum, should have a 1–2 sentence plain-language statement. For example, for ISO 45001: *"The global occupational health and safety management standard. Organizations certified to ISO 45001 have demonstrated systematic controls for workplace injury and illness — required by many government procurement processes and multinational supply chains."*

How to fix it: For the top 5,000 most-cited standards, a systematic enrichment pass is needed. This is the single highest-value work remaining in the project.

Gap 3.1.B — mandate field defaults to "Voluntary" for nearly everything

What is observed: The processing pipeline can heuristically assign "Mandatory" to entries with entry_type = Treaty. But for the 25,000+ ISO standards, 9,000+ IETF RFCs, and other bulk-ingested entries, the mandate is almost certainly defaulting to "Voluntary" — which is inaccurate for hundreds of entries.

Examples of incorrectly classified mandates:

• ISO 9001 is marked Voluntary globally but is *mandatory* for medical device suppliers in EU (MDR Annex IX), aerospace (AS9100 mandates it), and hundreds of national procurement rules
• IETF RFC 9110 (HTTP/1.1) is "Voluntary" in SIGMA but is the *de facto mandatory* standard for any web server
• GDPR references ISO/IEC 27001 in a way that makes it functionally mandatory for many organizations
• ISO 15118 (EV charging communication) is mandatory in the EU from 2025

Real-world consequence: Users relying on SIGMA for compliance checking will receive misleading information.

How to fix it: Add a mandate_notes free-text field alongside mandate enum; enrichment pass on the top 1,000 most-used standards; add a regulatory_references field linking to the regulation that makes a voluntary standard mandatory.

Gap 3.1.C — sub_domain is populated with ICS codes, not human-readable labels

What is observed: ISO's ICS (International Classification for Standards) codes use a numeric taxonomy (e.g., 11.040.10 = Anaesthetic, respiratory and reanimation equipment). The ingestion pipeline maps ISO entries to SIGMA domains, but sub_domain will contain ICS-derived labels rather than SIGMA's own plain-language sub-domain taxonomy.

Real-world consequence: Users filtering by sub_domain will see inconsistent labelling — ICS terminology for ISO entries, custom SIGMA labels for curated entries, and empty values for entries from other sources.

How to fix it: Build a canonical ICS-to-SIGMA-sub_domain mapping table. The ICS has 1,051 groups — mapping to SIGMA's sub_domain taxonomy is a one-time enrichment task.

Gap 3.1.D — year_first is missing for most entries

ISO Open Data provides year_published (current edition) but not year_first (original publication). This means the historical timeline for when a standard was first created is missing for ~25,000 ISO entries — a significant gap for researchers studying the evolution of international standardisation.

Gap 3.1.E — Dead or redirected URLs are not yet systematically flagged

The repository includes a scheduled URL health workflow and scripts/check_urls.py, but the report is not yet promoted into the public Pages surface or release-quality dashboard. Without visible monitoring, URL rot can still accumulate silently for WHO guidelines, UN documents, and national standards body pages that frequently restructure their portals.

---

GAP CATEGORY 3.2 — MISSING DATA SOURCES (NOT YET INGESTED)

These are confirmed free, publicly accessible sources that are not yet in the SIGMA pipeline based on the observed processing scripts.

Gap 3.2.A — IEC Standards Metadata (12,000+ standards) — NOT INGESTED

The gap: The IEC (International Electrotechnical Commission) has no equivalent of ISO's Open Data portal — there is no bulk-downloadable CSV. But IEC standard metadata *is* accessible through:

• IEC Webstore search (https://webstore.iec.ch/en/search): Paginated HTML results, scrapable
• IEC OC (Open Content) database: IEC publishes a limited set of standards as free PDFs — including all IEC 60268 (sound system equipment), IEC 61010 series (safety), and the "IEC Freely Available Standards" page at https://www.iec.ch/about/globalreach/publishers/free_pubs.htm
• Wikidata: Many IEC standards have Wikidata Q items (wdt:P123 wd:Q548172 for IEC as publisher)
• ISO/IEC JTC 1 standards are already in the ISO Open Data CSV (ISO and IEC jointly publish these through JTC 1)

Real-world consequence: The entire electrotechnical domain — which governs electrical safety of every device on earth, smart grid, renewable energy, medical electrical equipment (IEC 60601 series), industrial automation, and low-voltage electrical installations — is represented only by the JTC 1 subset (ICT standards). The IEC 60601 medical device electrical safety series, IEC 61000 EMC series, IEC 62443 industrial cybersecurity, and IEC 60364 wiring standards are missing.

How to fix it:

# Scrape IEC webstore search results (no login required for metadata)
# URL pattern: https://webstore.iec.ch/en/search?q=&p=1&size=100
# Pagination: up to ~120 pages of 100 results each
# Fields available: standard number, title, status, TC, year, edition

# Also: download IEC Freely Available Standards list
# URL: https://www.iec.ch/about/globalreach/publishers/free_pubs.htm

Gap 3.2.B — ITU Recommendations (5,000+) — NOT INGESTED

The gap: ITU publishes ITU-T (Telecommunication), ITU-R (Radiocommunication), and ITU-D (Development) recommendations. Since 2019, many are freely downloadable without registration at https://www.itu.int/rec/T-REC/en. The full list is accessible at:

• ITU-T recommendations index: https://www.itu.int/rec/T-REC/en
• ITU-R recommendations index: https://www.itu.int/pub/R-REC
• Both provide paginated HTML lists with standard numbers, titles, approval dates, and status

What is missing specifically:

• ITU-T X.509 (PKI certificates — the security foundation of the entire internet)
• ITU-T E.164 (international telephone numbering plan)
• ITU-T H.264/H.265 (video coding — used in every streaming service)
• ITU-T G series (transmission systems — backbone of telecom)
• ITU-T Y series (global information infrastructure, IoT, smart cities)
• ITU-R M series (mobile, radiodetermination, amateur)
• ITU Radio Regulations (the foundational international treaty for spectrum)

Real-world consequence: The telecommunications domain in SIGMA is built only on ISO/IEC JTC 1 entries. The actual standards governing global phone networks, broadcast, satellite communications, and internet routing are absent.

Gap 3.2.C — W3C Recommendations (400+) — NOT INGESTED

The gap: W3C publishes a full index of all Recommendations, Working Drafts, and Notes at https://www.w3.org/TR/?status=REC. This is a clean HTML page listing all published Recommendations with title, date, and link. A one-time scrape takes under 10 minutes.

What is missing:

• HTML5, HTML Living Standard reference
• CSS Cascade Levels 1–5
• WebAuthn (the global standard for passwordless authentication)
• WCAG 2.1 and 2.2 (web accessibility — legally required in EU, UK, USA)
• Linked Data standards (RDF, SPARQL, OWL, SKOS)
• WebAssembly (the standard for high-performance browser code)
• ARIA (accessibility for web applications)

How to fix it:

# Fetch https://www.w3.org/TR/?status=REC
# Parse the <dl> list items containing <dt> (standard title/link) and <dd> (date/status)
# Map to SIGMA schema: domain=Digital, sub_domain=Web Standards, issuer=W3C
# All W3C Recommendations are freely available; official_url = direct REC URL

Gap 3.2.D — NIST Publications (500+) — NOT INGESTED

The gap: All NIST Special Publications (SP 800 series for cybersecurity, SP 1800 series for practice guides), Federal Information Processing Standards (FIPS), and Internal Reports (NISTIR) are completely free at https://nvlpubs.nist.gov. NIST provides a full publications list at https://csrc.nist.gov/publications with JSON-style structured listings.

What is missing:

• NIST SP 800-53 Rev. 5 (Security and Privacy Controls — the most widely used cybersecurity control framework in the world, referenced by FedRAMP, DoD, and hundreds of regulations)
• NIST SP 800-171 (Protecting Controlled Unclassified Information — mandatory for all US DoD contractors)
• NIST SP 800-63 (Digital Identity Guidelines — the global benchmark for identity assurance)
• NIST FIPS 140-3 (Security Requirements for Cryptographic Modules — mandatory for US government systems)
• NIST SP 800-30 (Risk Assessment Guide)
• NIST SP 800-37 (Risk Management Framework)
• NIST AI RMF 1.0 and all supplementary resources

Gap 3.2.E — UN Treaty Collection (560+ multilateral treaties) — STAGING ACTIVE

The gap: The UN Treaty Collection at https://treaties.un.org is the authoritative registry for all multilateral treaties deposited with the UN Secretary-General. SIGMA now has an active UN/OHCHR staging slice for the nine core international human-rights treaties, but full chapter-by-chapter harvesting remains. The search interface returns structured HTML with treaty names, UNTS numbers, dates, and party counts. No bulk download API exists, but systematic scraping by chapter is straightforward.

What is missing: Every major UN-framework treaty except those manually curated in Phase 2:

• UNCLOS (UN Convention on the Law of the Sea) — binding on 169 states
• UNTOC (UN Convention Against Transnational Organized Crime) + Palermo Protocols
• UNCAC (UN Convention Against Corruption) — 190 state parties
• Vienna Convention on Consular Relations
• Vienna Convention on Diplomatic Relations
• Vienna Convention on the Law of Treaties
• Convention on the Rights of Persons with Disabilities (CRPD)
• Convention Against Torture (CAT)
• International Convention on the Elimination of All Forms of Racial Discrimination (CERD)
• International Convention on the Protection of the Rights of All Migrant Workers (CMW)

Gap 3.2.F — Codex Alimentarius — PARTIALLY INGESTED

The gap: Phase 2B ingested Codex standards, but the Codex Alimentarius Commission publishes standards across 8 categories totalling over 3,000 texts:

• Standards (commodity standards)
• Codes of Practice (Hygienic and Technological)
• Guidelines (food labelling, nutrition, contaminants)
• Maximum Residue Limits (MRLs) for pesticides — 5,000+ individual limits
• Maximum Limits for Contaminants
• Advisory Lists for Veterinary Drug Residues
• Standards for Methods of Analysis

The MRLs and contaminant limits are likely not yet structured as individual SIGMA entries (which would require a different entry type: Regulatory Limit), but the standards, guidelines, and codes of practice should all be in.

Gap 3.2.G — IAEA Safety Standards (250+ documents) — PRIORITY SLICE ACTIVE

The gap: The IAEA publishes its complete Safety Standards Series freely at https://www.iaea.org/resources/safety-standards. SIGMA now has an active priority slice for core Safety Fundamentals, General Safety Requirements, and Specific Safety Requirements, but full catalogue harvesting remains. All documents are free PDF. The full catalogue is organized into series:

• GSR: General Safety Requirements (9 parts)
• GSG: General Safety Guides (14 documents)
• SSR: Specific Safety Requirements (6 areas × multiple parts)
• SSG: Specific Safety Guides (80+ documents)
• GSR Part 3 (Radiation Protection) and associated guides
• Safety Reports Series (200+ volumes)

There is no process_iaea.py script visible in the Makefile, suggesting this source has not been systematically ingested.

Gap 3.2.H — GRI Standards (40+ documents) — NOT CONFIRMED INGESTED

All GRI Standards are freely downloadable from https://www.globalreporting.org/standards/download-the-standards/. There is no process_gri.py in the confirmed Makefile targets. The GRI Universal Standards (GRI 1, 2, 3) and Sector Standards (oil and gas, mining, agriculture, coal, financial services, food and agriculture) are foundational for sustainability reporting.

Gap 3.2.I — OECD Publications — NOT INGESTED

The gap: OECD publishes hundreds of standards, guidelines, principles, and frameworks, most freely accessible at https://www.oecd.org. Key missing items:

• OECD Guidelines for Multinational Enterprises (2023 update)
• OECD Transfer Pricing Guidelines 2022
• OECD Principles of Corporate Governance
• OECD Anti-Bribery Convention and commentary
• OECD Due Diligence Guidance for Responsible Business Conduct
• OECD DAC Evaluation Criteria (2019)
• OECD AI Principles (adopted by 42+ countries)
• OECD Privacy Guidelines (revised 2013)
• OECD Guidelines for the Security of Information Systems
• OECD Responsible Business Conduct standards

Gap 3.2.J — OpenStreetMap/OGC Geospatial Standards — NOT INGESTED

The gap: The Open Geospatial Consortium (OGC) at https://www.ogc.org/standards publishes open standards for geospatial data that are foundational to all GIS, mapping, and location-based services:

• OGC WMS (Web Map Service)
• OGC WFS (Web Feature Service)
• OGC GeoJSON
• OGC API standards
• GeoPackage
• CityGML (3D city models)
• IndoorGML (indoor navigation)

These standards underpin all humanitarian mapping (UNHCR, REACH, HDX), disaster response GIS, and development programme monitoring. This is a significant gap given the project's humanitarian use case.

---

GAP CATEGORY 3.3 — MISSING OR UNDER-COVERED DOMAINS

Based on observed processing scripts and confirmed data sources, these domains are either completely absent or have only skeleton coverage.

Gap 3.3.A — Sports & Recreation (Domain 22) — INITIAL PRIORITY SLICE ACTIVE

SIGMA now has an active Phase 7B priority ingestor for:

• WADA World Anti-Doping Code 2021 — https://www.wada-ama.org/en/what-we-do/world-anti-doping-code

• ICCROM First Aid to Cultural Heritage in Times of Crisis

Remaining work: expand beyond the initial priority slice into the full ICOMOS doctrinal text catalogue, ICCROM publication families, additional UNESCO culture instruments, and relationship links to humanitarian response, education, indigenous rights, environment, and disaster risk.

Gap 3.3.C — Space & Satellite (Domain 14) — SKELETON ONLY

ISO TC 20 SC 14 metadata is present (via ISO Open Data), and SIGMA now has an active CCSDS/ECSS priority slice, but full catalogue expansion remains:

• CCSDS standards (Consultative Committee for Space Data Systems) — all 200+ Blue Books freely available at https://public.ccsds.org/Publications/BlueBooks.aspx — priority slice active; full harvest needed
• ECSS (European Cooperation for Space Standardisation) — free at https://ecss.nl/standards — priority slice active; full harvest needed
• ITU Radio Regulations (the treaty governing satellite orbital slots) — NOT ingested (linked to ITU gap)
• Space debris mitigation guidelines (IADC, COPUOS) — NOT ingested
• Launch vehicle interface standards (EELV, GEVS) — most are free

Gap 3.3.D — Marine & Ocean (Domain 37) — PARTIAL

IMO conventions are referenced but not systematically ingested:

• Full text and amendment list for each IMO Convention (SOLAS, MARPOL, STCW, ISPS, MLC 2006, Ballast Water, Polar Code)
• UNCLOS (560+ articles; the constitution of the oceans) — not confirmed as an individual entry

• Convention on Cluster Munitions — https://www.clusterconvention.org — NOT confirmed ingested

---

GAP CATEGORY 3.4 — INFRASTRUCTURE & AUTOMATION GAPS

Gap 3.4.A — GitHub Actions Workflows Need a Unified Full CI Gate

What is observed: The repository has GitHub Actions for schema validation, release artifact build, URL health checks, and GitHub Pages publishing. The Makefile has a validate target that exercises the broader local quality gate.

Remaining gap: The existing workflows are split by purpose. The project still benefits from one explicit ci.yml workflow that runs make validate and the pytest suite on every push and pull request.

What this means: Schema validation exists, but a single comprehensive CI workflow gives contributors a clearer pass/fail signal and reduces the chance that report generation, staged harvest fixtures, or static-site rendering regress unnoticed.

What needs to be created or strengthened:

1. ci.yml — run make validate and pytest on every PR and push to main.
2. Keep the monthly URL health workflow, but publish or upload its report.
3. Keep release and Pages workflows aligned with make release and make site.

Gap 3.4.B — GitHub Pages Site Exists; Search and Facets Are Still Missing

What is observed: build_static_site.py generates a designed GitHub Pages site with navigation, release downloads, domain coverage, source registry rows, project progress, owner contact, and rendered project documentation.

Remaining gap: The site is not yet a full search interface. It does not yet offer full-text search, faceted filtering, or entry-level pages.

What the world's best resource needs:

• Full-text search across all 88,114 entries (Pagefind is a free static site search tool that works with GitHub Pages — https://pagefind.app)
• Filter by domain, layer, entry type, mandate, and geographic scope
• Individual entry pages (or at minimum, a URL like sigma-standards.github.io/entry/HL-ISO-15189-2022)
• Downloadable releases: sigma_complete.csv, sigma_complete.json, sigma_complete.parquet, sigma_bodies.csv, sigma_treaties.csv, sigma_relationships.csv
• Coverage badge in README showing live entry count and domain coverage

Gap 3.4.C — No Zenodo DOI (Not Yet Published as Citable Dataset)

What is missing: A Zenodo DOI gives the dataset a permanent, citable academic identifier. It enables researchers to cite SIGMA in publications. It provides long-term archival. It is free at https://zenodo.org (no credit card — just a CERN/GitHub login).

How to set it up: Connect the GitHub repository to Zenodo (Settings in Zenodo; then create a new version release — Zenodo automatically archives the release and assigns a DOI).

Gap 3.4.D — No REST API

What is missing: A simple query API that allows programmatic access to the index — GET /api/entries?domain=Health&entry_type=Standard — without downloading the full CSV.

How to build it for free: Netlify Functions or Cloudflare Workers (both have free tiers, no credit card required for free plan) can serve a simple JSON API from the static CSV data. Alternatively, DoltHub provides a free hosted SQL database with a REST API from CSV imports — https://www.dolthub.com.

GAP CATEGORY 3.5 — COMMUNITY & VISIBILITY GAPS

Gap 3.5.A — Zero Community Engagement (0 Forks, 0 Stars, 0 Issues, 0 PRs)

What is observed: The repository has 0 forks, 0 stars, 0 open issues, and 0 pull requests as of the analysis date.

What this means for sustainability: A project with no external contributors is entirely dependent on one person's continued engagement. If the maintainer's time is reduced (which is likely for a health programme manager with a full-time job), the project stagnates. The relationship graph and why_it_matters enrichment both require community contributions at scale to be completed.

What to do immediately: Five specific outreach actions:

1. Submit to Humanitarian Data Exchange (HDX) at https://data.humdata.org/dataset/new — free, no credit card; HDX serves 80,000+ humanitarian users and provides permanent hosting backup
2. Post to the IATI Community Forum at https://discuss.iatistandard.org — SIGMA directly complements IATI's transparency mission and the IATI community is active
3. Submit to ALNAP — the global humanitarian learning network at https://www.alnap.org; email alnap@odi.org with a one-paragraph description
4. Post on OpenStreetMap Forum and HOT (Humanitarian OpenStreetMap Team) mailing lists — geospatial standards overlap significantly
5. Create a LinkedIn Organisation page for sigma-standards — free, drives discovery by professionals

Gap 3.5.B — README Does Not Show the Data

What is observed: The README describes the project but does not show a sample of the actual data. A potential contributor landing on the repository does not see any entries.

What it should show: A table of 5–10 example entries in the README, demonstrating what a complete record looks like — with sigma_id, name_short, domain, why_it_matters, mandate, and official_url all populated. This is the single most effective change to drive contributions.

Gap 3.5.C — Issue Templates Exist; Structured Forms Should Be Expanded

What is observed: The repository currently has Markdown issue templates for new entries and error corrections.

What should exist:

• new-standard.yml — structured form for submitting a new standard entry with all 22 fields.
• new-body.yml — structured form for submitting a new standards body.
• error-report.yml — structured form for reporting inaccurate data with source evidence.
• domain-request.yml — structured form for requesting expansion of a specific domain.

---

GAP CATEGORY 3.6 — SCHEMA COMPLETENESS GAPS

The current 22-field schema is good but has documented holes.

Gap 3.6.A — No language Field

SIGMA currently has no field tracking what language(s) a standard is published in. This matters because:

• WHO guidelines are in all 6 UN languages (Arabic, Chinese, English, French, Russian, Spanish)
• ILO Conventions are in English and French (equally authentic texts)
• Some ISO standards are published only in English; others in EN/FR/RU
• Many national standards are only in the national language

A languages field (comma-separated ISO 639-1 codes) enables multilingual users to find standards in their language.

Gap 3.6.B — No last_verified_date Field

Without tracking when an entry was last verified, users cannot assess data freshness. A standard marked Active that was last verified in 2023 may have been revised or withdrawn. The last_verified_date field (ISO 8601 date, populated by the URL health check script) enables users to filter for recently verified entries and identify stale records.

Gap 3.6.C — No abstract or scope_statement Field

The why_it_matters field is intended for plain-language explanation, but there is no field for the standard's own official scope statement. The official ISO scope statement for ISO 15189 reads: *"This document specifies requirements for quality and competence in medical laboratories."* This is distinct from the why_it_matters narrative and provides a verifiable, source-attributed description.

Recommendation: Add scope_statement (the issuer's own official scope, quoted verbatim, max 300 characters) alongside the existing why_it_matters field.

Gap 3.6.D — LLM-Suggested Relationships Not Yet Reviewed

What is observed: The SCHEMA.md explicitly warns: *"LLM-suggested relationships must not be published as final graph edges until a human reviewer confirms the source."* The 20,140 relationship edges are confirmed to exist, but the confidence levels of these edges are unknown. If the majority are llm-suggested rather than source-confirmed or curator-reviewed, the relationship graph is not yet publication-quality.

Gap 3.6.E — No replaces / replaced_by Cross-Reference in Main Schema

When a standard is superseded (e.g., ISO 15189:2022 supersedes ISO 15189:2012), this relationship exists in the relationships table but not in the main entry table. Users looking at a Withdrawn entry have no in-row pointer to the current replacement. A replaces_sigma_id and replaced_by_sigma_id field pair in the main schema would make this immediately visible.

---

GAP CATEGORY 3.7 — PROCESS & GOVERNANCE GAPS

Gap 3.7.A — No Public Roadmap or GitHub Project Board

What is observed: The detailed roadmap exists as a Markdown file in docs/superpowers/plans/. But there is no GitHub Project board, no milestone tracking, and no public-facing roadmap that a prospective contributor can consult to understand what work is most needed.

What to do: Create a GitHub Project (free) with a Kanban board showing the 9 phases from the Research Project Plan. Each Makefile target becomes a card. This takes 30 minutes and dramatically increases the ability to attract contributors.

Gap 3.7.B — No Defined Domain Expert Review Process

What is observed: The Research Project Plan describes domain expert reviews in Phase 9. But no current process exists for inviting domain experts or tracking their reviews.

What to do: Create a DOMAIN_EXPERTS.md file listing the 40 domains with a "Domain Lead" column (initially empty for most), contact information for interested reviewers, and the review criteria. Even an empty table signals that domain expert contributions are welcome.

Gap 3.7.C — Google Sheet is Not Publicly Linked

What is observed: sync_google_sheet.py syncs from a Google Sheet into data/processed/google_sheet_master.csv. But the Google Sheet URL is not in the README or CONTRIBUTING.md.

What this means: Potential non-technical contributors — field workers, humanitarian practitioners, subject matter experts who know standards but not Python — cannot contribute to the curation layer without knowing this link. This is a significant barrier for the most knowledgeable potential contributors.

What to do: Either (a) make the Google Sheet publicly viewable (view-only) and link from README, or (b) add a GitHub Issues form as the primary curation input for non-technical contributors.

---

GAP CATEGORY 3.8 — DISCOVERABILITY & USER EXPERIENCE GAPS

Gap 3.8.A — No Search Demo or Live Interactive Preview

A user landing on the repository currently has no way to search the 88,114 entries without downloading a large CSV file. This creates a significant barrier for casual users — the people most likely to cite, share, and champion the project.

What to add:

• Link to a live searchable view on Google Sheets (view-only; free)
• Datasette deployment on Fly.io or Glitch (both free tiers; no credit card for Glitch)
• Observable notebook with interactive domain browser

Gap 3.8.B — No Social Preview Image / Repository Card

The GitHub repository card shows only text. A social preview image (showing the SIGMA branding, entry count, domain coverage) would dramatically increase click-through rate when the repository link is shared on social media or in publications.

Gap 3.8.C — No Badge in README Showing Live Stats

README badges for entry count, domain coverage, URL health status, and license create immediate credibility signals. These are free via shields.io.

![Entries](https://img.shields.io/badge/entries-88%2C114-brightgreen)

4. DOMAIN-BY-DOMAIN COVERAGE AUDIT

Based on confirmed processing scripts and data sources, here is the honest coverage assessment for each of the 40 domains.

Summary:

• Near-complete (75%+): Labour (ILO), Human Rights (OHCHR)
• Good coverage (50–74%): Food Safety, Health, OHS, ICT, Marine
• Moderate coverage (30–49%): Manufacturing, Finance, Trade, ESG, Energy, Environment, Disaster Risk
• Thin coverage (10–29%): Pharmaceuticals, Aerospace, Space, Legal, Governance, Education, Transport, Defence
• Essentially empty (<10%): Extractive Industries

5. PRIORITY ACTION PLAN — WHAT TO FIX FIRST

Ranked by impact-to-effort ratio. Each action has a concrete next step.

PRIORITY 1 — CRITICAL (Do This Week)

P1.1 — Activate GitHub Actions CI workflow Create .github/workflows/ci.yml that runs make validate on every push and PR. This prevents schema-breaking changes from being merged silently.

name: CI
on: [push, pull_request]
jobs:
  validate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with: {python-version: '3.11'}
      - run: pip install -e .
      - run: make validate

P1.2 — Link the Google Sheet from README Add a link to the curation Google Sheet (or a view-only copy of it) in the README under a "Contribute Without Coding" section. This opens the project to hundreds of potential non-technical contributors.

P1.3 — Add Sample Data Table to README Replace the current abstract description with 5 fully-populated example entries in a Markdown table. Show sigma_id, name_short, domain, why_it_matters, mandate, and official_url. This is the single most effective change for attracting contributors.

P1.4 — Submit to HDX (Humanitarian Data Exchange) Submit the dataset to https://data.humdata.org. OCHA HDX is the premier humanitarian data platform. A SIGMA dataset page here would expose the project to the entire humanitarian sector immediately. Required fields: title, description, license (CC BY 4.0), file uploads (CSV). No credit card. Free.

---

PRIORITY 2 — HIGH IMPACT (Do This Month)

P2.1 — Ingest IEC Standards Metadata Write scripts/harvest_iec.py to scrape IEC Webstore search results. 12,000+ entries. Significantly fills the Electrical & Electronics domain gap. Free data.

# Base URL: https://webstore.iec.ch/en/search?q=&p={page}&size=100
# Parse: standard number, title, status, TC, year, edition
# Map to SIGMA schema, domain=Electrical & Electronics

P2.2 — Ingest All W3C Recommendations Write scripts/harvest_w3c.py targeting https://www.w3.org/TR/?status=REC. ~400 entries. 1–2 hours of work. Fills key web standards gap in ICT domain.

P2.3 — Ingest NIST SP 800 + FIPS Series Write scripts/harvest_nist.py targeting https://csrc.nist.gov/publications/search?status=Final&series=SP. ~180 SP 800 publications + all FIPS. Free, fully structured JSON metadata available.

# NIST CSRC API: https://csrc.nist.gov/CSRC/media/Projects/publications-search/api-docs.pdf
# Returns structured JSON with: title, doi, date, abstract, series, type, status

P2.4 — Ingest IAEA Safety Standards SIGMA now has an active IAEA priority slice. The next step is scripts/harvest_iaea.py for full catalogue coverage. All IAEA Safety Standards are free PDF. The catalogue page at https://www.iaea.org/resources/safety-standards lists all documents. ~250 entries covering nuclear safety, security, safeguards.

P2.5 — Ingest CCSDS Blue Books (Space Standards) https://public.ccsds.org/Publications/BlueBooks.aspx — the full list of space data communications standards. All free. SIGMA now has an active CCSDS/ECSS priority slice; the remaining work is full catalogue harvesting and enrichment.

P2.6 — Enrich why_it_matters for Top 500 Standards Identify the 500 most globally significant standards (by citation frequency, adoption rate, or regulatory mandating). Write a batch enrichment pass. These are the entries users are most likely to encounter and where empty fields do the most damage to SIGMA's credibility.

---

PRIORITY 3 — IMPORTANT (Do This Quarter)

P3.1 — Ingest ITU-T and ITU-R Recommendation Lists Scrape https://www.itu.int/rec/T-REC/en for ITU-T and https://www.itu.int/pub/R-REC for ITU-R. ~3,000–5,000 entries. Fills the telecom/ICT domain significantly.

P3.2 — Ingest GRI and SASB Standards GRI: https://www.globalreporting.org/standards/download-the-standards/ — 40+ documents, free SASB: https://sasb.org/standards/ — 77 industry standards, free Both critical for the Sustainability domain.

P3.3 — Ingest UN Treaty Collection SIGMA now has an active UN/OHCHR core human-rights treaty staging slice. The next step is scripts/harvest_untreaties.py to systematically scrape by chapter (UNTC organises by subject: I. Charters, II. Environment, III. Human Rights, etc.). ~560 multilateral treaties. Required for completeness of Human Rights, Environment, and Disarmament domains.

P3.4 — Expand Sports & Recreation Domain Content Initial WADA, IOC, IFAB, World Athletics, CAS, FIBA, and ITF records are active. Continue manual curation toward FIFA legal instruments, UNESCO anti-doping treaty records, ISO TC 83 sports equipment tagging, safeguarding frameworks, and sport-specific playing-condition libraries.

P3.5 — Add Culture & Heritage Domain Content Manual curation of UNESCO Conventions, ICOMOS Charters, ICOM Code. ~40–50 entries. All free. This domain is completely empty.

P3.6 — Add language, last_verified_date, scope_statement Fields to Schema Update SCHEMA.md to add three fields. Update all processing scripts to populate them. Run a first pass of the URL health check to populate last_verified_date for all existing entries.

P3.7 — Create GitHub Project Board Enable GitHub Projects. Create a board with columns: Backlog | In Progress | Review | Done. Populate with one card per Makefile target and per domain gap. This takes 30 minutes and transforms the project's accessibility to contributors.

P3.8 — Deploy Live Searchable Interface Build with Datasette on Fly.io (free tier):

1. pip install datasette datasette-publish-fly (free tool)
2. datasette publish fly data/processed/sigma_master.db --app=sigma-index (free Fly.io hobby tier)
3. Result: a live SQL-queryable web interface at https://sigma-index.fly.dev

P3.9 — Submit to Zenodo for Permanent DOI

1. Go to https://zenodo.org — login with GitHub (free, no credit card)
2. Connect the sigma-standards/sigma-index repository
3. Create a GitHub Release tagged v1.0
4. Zenodo auto-archives the release and assigns DOI

---

PRIORITY 4 — LONGER TERM (Next 6 Months)

P4.1 — Multilingual entries for French, Spanish, Arabic WHO, ILO, UN all publish in 6 languages. Add name_full_fr, name_full_es, name_full_ar to the schema and populate for all UN-system entries.

P4.2 — Ratification/Adoption Tracker populated The schema for the ratification_tracker table exists as a template. Populate it with OHCHR treaty ratification data (free JSON downloads) for the 9 core human rights treaties × 193 countries = ~1,700 rows as a starting dataset.

P4.3 — Relationship graph review and validation Human-review the 20,140 relationship edges; confirm or reject LLM-suggested ones with source citations. Publish only source-confirmed and curator-reviewed edges in official releases.

P4.4 — Build REST API Deploy a minimal read-only API on Cloudflare Workers (free tier — 100,000 requests/day free, no credit card with free plan via CLI deployment).

8. THE PATH TO WORLD'S BEST RESOURCE

Being the world's best free unified index of global standards requires excelling on four dimensions simultaneously: completeness, quality, usability, and sustainability. Here is the honest assessment of where SIGMA stands and what would make it definitively the best.

8.1 Completeness — From 88,114 to 120,000+ Entries

The current 88,114 entries is excellent but has structural gaps. Adding the missing sources identified in this analysis would bring the index to approximately:

At 107,000+ entries covering all 40 domains with no empty ones, SIGMA would be the most complete free standards index ever built. No comparable resource exists.

8.2 Quality — From Bulk Metadata to Enriched Knowledge

Entry count is necessary but not sufficient. The transition from "metadata dump" to "knowledge resource" requires:

1. why_it_matters enriched for top 5,000 entries — covering all major standards that general users will encounter. The remaining 100,000+ entries can have this field empty initially, with a community enrichment programme over time.

1. Mandate classification verified for top 500 entries — with specific mandate_notes documenting which regulations make which voluntary standards de facto mandatory.

1. Relationship graph published with confidence levels — only source-confirmed and curator-reviewed edges in the public release; LLM-suggested edges clearly flagged as provisional.

1. Ratification tracker populated for the 9 core UN human rights treaties — 193 countries × 9 treaties = 1,737 rows. This dataset is transformatively useful for human rights researchers and is available free from OHCHR.

8.3 Usability — From GitHub Repo to Public Resource

The most important gap right now is usability for non-technical users. SIGMA's target audience — humanitarian workers, health programme managers, regulators in low-income countries, educators — cannot use a raw CSV. Solving this requires exactly three things:

1. A live searchable interface — Datasette on Fly.io, or GitHub Pages with Pagefind. Either can be done for free in one afternoon.
2. Download links for formatted outputs — Clearly linked in the README: download CSV, download JSON, download Excel. Currently unclear whether a release bundle is published.
3. Domain landing pages — One page per domain on the GitHub Pages site, showing entry count, key bodies, most important standards, and links to contribute.

8.4 Sustainability — From Solo Project to Community Resource

The most important structural risk to SIGMA is that it is entirely built and maintained by one person. The community metrics (0 forks, 0 stars, 0 issues, 0 PRs) show that the community-building phase has not yet begun.

Five things that would transform this within 60 days:

1. Submit to HDX — HDX has 80,000+ registered users in the humanitarian sector; even 50 of them discovering and using SIGMA creates momentum
2. Post in humanitarian tech forums — GODAN (Global Open Data for Agriculture and Nutrition), IATI developer forum, Digital Impact Alliance
3. Reach out to academic libraries — University libraries that maintain reference databases (Cornell, LSE, SOAS, BRAC University) are natural institutional partners
4. Create a domain-specific fork example — Show that someone running a health programme (like CPI Bangladesh) can create a domain-filtered fork of SIGMA (sigma-health-index) customised to their sector — this demonstrates the value of the core project
5. Tag the first GitHub release — A v1.0 tag with proper release notes and downloadable artifacts creates a citable, permanent snapshot that partners can reference

---

FINAL VERDICT

sigma-standards/sigma-index is genuinely impressive as an early-stage project. The data volume (88,114 entries), the schema design (22 fields including the critical why_it_matters and mandate fields), the build pipeline (14 Makefile targets, proper Python packaging), and the governance documentation (CC BY 4.0, SCHEMA, CONTRIBUTING) collectively represent more serious investment than most comparable open data projects ever achieve.

The gaps are real but tractable. The most critical ones — IEC ingestion, W3C ingestion, NIST ingestion, activating GitHub Actions CI, submitting to HDX, linking the curation Google Sheet — can all be addressed in under two weeks of focused work. None require money, subscriptions, or credit cards.

The path from where SIGMA is today to genuinely being the world's best free unified index of global standards is clear, doable, and entirely within reach using the free tools and free data sources documented in this analysis.
