The duty to publish sits in the city code, and the compliance record is itself a dataset — which is how anyone can count the 474 inventoried datasets that are still unpublished.
what does this mean?
The strongest source is the operator's or the city's own reporting — an official report, dataset or press release. It grades who did the looking — not how well the project went. All four grades →Part of 1001 Smart Cities — 1,167 documented projects · 🏙️ 9 more in San Francisco · 📊 Open data guide · 📡 Data & IoT projects
San Francisco's portal opened in 2009 under Mayor Newsom's Executive Directive 09-06. A 2010 ordinance put the duty into Administrative Code Chapter 22D; a 2013 ordinance added a Chief Data Officer and department data coordinators. Unusually for a US city, the data carries a recognised open licence, PDDL 1.0, and the inventory Chapter 22D requires is itself published as a dataset.
📊 Impact
659 datasets in the portal catalogue, read 26 July 2026; police incident reports are republished daily and were current that day. The inventory the ordinance requires is public and was refreshed the same day: of 1,308 inventoried datasets, 696 are marked published, 474 not published, 77 internal, 51 in progress and 7 in scoping. 153 published datasets that are not flagged historical had gone more than a year without a data update.
🎓 Lesson
An executive order can lapse with the administration that signed it. San Francisco put the duty in the code and publishes the compliance record itself as a dataset — which is why anyone can count the 474 inventoried datasets that are still unpublished without asking the city.

The origin instrument, independently transcribed and analysed. Date: 'October 21, 2009', issued by Mayor Gavin Newsom. Carrying duties: 'All Department Heads or their designees shall strive to publish all datasets under their authority consistent with the DataSF authorization policy', with quarterly reviews of progress, and 'All datasets determined to be accessible to the public now and in the future shall be made available through DataSF.org.' The directive names the portal but does not date its launch.

The operative text, published by the city itself. SEC. 22D.2(a) makes the Chief Data Officer responsible for coordinating the portal, assisting departments with compliance and analysing usage, and (a)(5) to 'Present an annual updated citywide implementation plan to COIT, the Mayor, and…' the Board. SEC. 22D.2(b)(3) requires each department Data Coordinator to 'Prepare an Open Data plan for the Department', including 'a summary description of all data sets under the control of each…' department and 'a timeline for the publication of the Department's open data'. This is the sentence-level basis for the inventory and publishing-plan machinery.

The 2013 strengthening. Ordinance numbers reported in secondary summaries of this chain — Ordinance 293-10 (2010) codifying the policy as Administrative Code Chapter 22D, Ordinance 69-13 passed 16 April 2013 creating the Chief Data Officer and Department Data Coordinators — were not confirmed against the clerk's file, which is why the entry body says 'a 2010 ordinance' and 'a 2013 ordinance' rather than citing numbers.

The accountability artefact, and what San Francisco publishes that the peer cities do not: the Chapter 22D inventory is itself an open dataset, with one row per departmental dataset carrying publishing_status, department, priority, date_published, update_frequency and days_since_data_update. Read 26 July 2026: data_updated_at 2026-07-26T02:12:31Z. The dataset's own description states it is 'collected in accordance with Chapter 22D of the Administrative Code'.

Sentence-level source for every number in the impact field, read 26 July 2026: Published 696, Not Published 474, Internal 77, In Progress 51, Scoping 7, blank 3 — 1,308 records. The 696 'published' inventory records exceed the 659 live catalogue datasets; the two count different things (departmental publishing records versus current portal assets) and are reported separately rather than reconciled. The staleness figure comes from a second query on the same dataset: publishing_status='Published' plus days_since_data_update over 365 and update_frequency not historical returns 153.

What the licence actually grants, for readers comparing the atlas's licence positions: a dedication of the database to the public domain, with no attribution and no share-alike condition. This is the most permissive position of any city in the atlas — more permissive than Vienna's CC BY 4.0, and unlike New York (statutory ban on licence conditions but no deed shipped), Chicago (no deed, plus a notice condition on reusers), Jakarta (asserted public-domain status, no deed), Shanghai and Bangkok (no licence at all).

Currency, and a sign the portal is still the city's compliance vehicle rather than a legacy site: the presentation sets 18 July 2025 as the deadline for the CIO's initial publication of the AI inventory on the City's Open Data Portal, with a comprehensive inventory update due 18 January 2026.

Example of downstream reuse, labelled honestly as an example and deliberately kept out of the impact field. The page credits its data to SF OpenData and the US Census Bureau; the Anti-Eviction Mapping Project, active since 2013, works from the same Rent Board eviction-notice records published on the portal. The crediting sentence was read from the search index rather than a successful fetch. No source ranks the portal's usage, so no 'most used' claim is made.

Known limits of this passport
- Publisher names and source languages have not yet been classified; domains are recorded without guessing.
- Existing source notes are descriptive locators, not page- or paragraph-exact citations.
- A missing archive, publication date or content hash is shown as null rather than inferred.
- The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
