Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-f217d87130580d9c quantitative

Bristol City Council publishes its open data on an Esri ArcGIS Hub site at opendata.bristol.gov.uk, created in October 2022

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The site item behind the domain carries 'url':'https://opendata.bristol.gov.uk' and 'created':1666798721000, which is 26 October 2022, with typeKeywords 'hubSite' and 'OpenData' identifying it as an Esri ArcGIS Hub site.
Caveat: The date is the creation of this ArcGIS Hub site, not the launch of Open Data Bristol. An earlier portal of the same name ran on Socrata software; no reachable source dates that launch, which is why the entry carries no start year.

Claim 2 clm-d8df48308b2fb459 descriptive

run from the council's own ArcGIS organisation

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The site item gives 'orgId':'a4vR8lmmksFixzmB'; the organisation record for that id reads 'name':'Bristol City Council' with urlKey 'bcc'. Every catalogue item is owned by an account in that organisation.
Caveat: No claim-specific caveat recorded

Claim 3 clm-02259436cfabf7d1 quantitative

its single catalogue group held 210 items

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The site item's catalog definition names exactly one group, c750a490d152430a9aefe9b1fba0ec14. A search restricted to that group on 25 August 2026 returned '"total":210'.
Caveat: No claim-specific caveat recorded

Claim 4 clm-88ef008c7ce33644 quantitative

of which 202 are data: 190 feature services, 10 links out to documents and 2 PDFs

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Paging all 210 records and counting the type field gives 190 Feature Service, 10 Document Link, 2 PDF, 4 Hub Page, 2 Web Experience, 1 Dashboard and 1 Web Map. The first three types are data; the remaining eight items are pages, dashboards and a web map.
Caveat: The split between data and not-data is our reading of the platform's type field, not a label the portal applies.

Claim 5 clm-a7d1799417c26332 quantitative

The council's open data page states that its open data is released under the Open Government Licence 3.0

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Verbatim on the council's open data page: 'Our open data is released under the Open Government Licence 3.0 (OGL 3.0). This explains what you can and cannot do with the data.' The linked licence is version 3 at nationalarchives.gov.uk.
Caveat: No claim-specific caveat recorded

Bristol City Council, Open data (authority)

Claim 6 clm-b3cea07b3cd8df7b descriptive

data may be reused as long as you follow the terms of its licence, and in most cases this is the Open Government Licence

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Verbatim from the portal's terms of use: 'You can use data from Open Data Bristol as long as you follow the terms of its licence. In most cases this is the Open Government Licence.' The link on that phrase points at version 3.
Caveat: No claim-specific caveat recorded

Claim 7 clm-b65af49ab34d8384 descriptive

the licence is a free-text field rather than a controlled one

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The platform stores the licence as licenceInfo, an unconstrained HTML text field, and the catalogue uses it as such: the 202 data items carry 44 distinct non-empty strings, ranging from the two words 'Open Government Licence' to multi-sentence disclaimers, with no controlled value anywhere.
Caveat: No claim-specific caveat recorded

ArcGIS sharing API, catalogue census over the site's group (operator API)

Claim 8 clm-95c16a3ffd1ecd2d descriptive

no dataset in the catalogue carries a Creative Commons licence or a public-domain dedication

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Searching the licenceInfo string of all 202 data items for 'creative commons', 'CC BY', 'public domain' and 'CC0' returns zero matches.
Caveat: A computed absence across the catalogue rather than a passage on a page; the reviewer can reproduce it from the cited search endpoint.

Claim 9 clm-4881c94d3ab9d444 quantitative

113 name the Open Government Licence in free text, and only 23 of those state which version

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Of the 202 data items, 113 licenceInfo strings contain 'Open Government Licence' or 'Open Government License'; 23 of those also state a version, and every version named is 3. The remaining 90 name the licence with no version. One further item reads only 'Open Government Data', which is not a licence name and is not counted here.
Caveat: The Open Government Licence exists in versions 1, 2 and 3, and all three require attribution; a bare 'Open Government Licence' does not say which one applies.

Claim 10 clm-f45dfa367fd75c7f quantitative

40 carry no licence text at all

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: 40 of the 202 data items have an empty or absent licenceInfo. Ten of the 40 were re-fetched from the per-item endpoint and confirmed empty there too, so this is not an artefact of the search response.
Caveat: No claim-specific caveat recorded

Claim 11 clm-bfc61b0e30999407 quantitative

38 carry an Ordnance Survey copyright line, and 35 of the 202 still contain an unfilled template placeholder where the year of supply should be

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: 38 licenceInfo strings mention Ordnance Survey. 35 of the 202 contain '[insert year of supply]', '[year of supply]' or '[year]' unreplaced, for example 'Copyright : (c) Crown Copyright and database rights [insert year of supply] Ordnance Survey 100023406.'
Caveat: A copyright line is not a licence: it names an owner without granting a permission.

Claim 12 clm-08b0b503a3c30f6a quantitative

7 point instead at the Ordnance Survey INSPIRE End User Licence, a public-sector re-use licence rather than an open one

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: 7 licenceInfo strings cite the INSPIRE End User Licence and name no other licence, in the form 'By using or accessing this data the INSPIRE End User is deemed to have accepted the Public Sector End User Licence - INSPIRE'. The datasets are Recycling banks, Allotment plots, Sites of Nature Conservation Interest, Neighbourhood planning areas, Article 4 Directions, Solar Potential and City docks water.
Caveat: The characterisation of the INSPIRE End User Licence as a public-sector rather than an open licence is the atlas's reading of what the licence is for; the count of 7 is measured.

Claim 13 clm-354f5266ebc5c603 descriptive

one dataset, Bus Stops, reads 'Caveat : Non-commercial use only'

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The whole of the Bus Stops item's licenceInfo is the string 'Caveat : Non-commercial use only'. The item is public and owned by the council's Layer_Library account.

What the mapping says: The BMX facilities item's licenceInfo opens '(c) betterbybike.info 2022. All Rights Reserved.' followed by a third-party website disclaimer. The phrase occurs twice in the item record, both times in this reservation of rights.

Claim 15 clm-69904491722198cf quantitative

70 of the 201 datasets present expose a licence a machine can resolve, 69 of them the Open Government Licence v3 URL and one an NHS terms page, while 39 expose an empty licence field

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The DCAT-US feed served at /api/feed/dcat-us/1.1.json holds 223 rows covering 209 catalogue items, of which 201 are data items. Reduced to those unique items, 70 carry a licence value that is a URL (69 the OGL v3 URL at nationalarchives.gov.uk, 1 a developer.api.nhs.uk terms page), 39 carry an empty licence value and 92 carry free text that is not a URL.
Caveat: Counted per unique dataset, not per feed row: multi-layer services appear once per layer. One data item, Street Improvements, is missing from the feed entirely.

Claim 16 clm-8f95e7de17ddd017 quantitative

of the 41 datasets hosted on Esri's cloud, which report a last-edit date, 13 were last edited in 2026 and two on the day of counting, while 16 have not been edited since November 2022

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: 41 of the 190 feature services resolve to services2.arcgis.com under the council's organisation and every one of them returns an editingInfo.lastEditDate. On 25 August 2026 those dates fell in 2026 for 13 services, 2025 for 7, 2024 for 3, 2023 for 1, November 2022 for 16 and 2020 for 1. AirQualityContinuousLatest and Surface Water Quality both carried a last edit on the day of counting.
Caveat: The item-level 'modified' timestamp is useless as a freshness signal here: 133 of the 202 items were stamped on 5 September 2025 and 44 more on 25 September 2025, a bulk metadata operation rather than an update to the data.

Claim 17 clm-7daba49743b63ef2 quantitative

Bristol Waste Monthly holds 11 rows ending 4 January 2020

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: A maximum-statistic query on the service's Date field returns 1578096000000, which is 4 January 2020; a returnCountOnly query on the same layer returns 11. The service's own editingInfo.lastEditDate is 25 November 2022.

Claim 18 clm-8e4f2ef56376bdff quantitative

The other 149 feature services sit on the council's own map server and expose no edit date at all

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: 149 of the 190 feature services resolve to maps2.bristol.gov.uk/server2, which serves MapServer endpoints. Sixteen of them were queried and all responded, but none returns an editingInfo block, so no comparable currency census is possible for them.
Caveat: They answered when queried, so this is a limit on what can be measured, not evidence that those datasets are stale.

who has to read 44 distinct licence strings to learn what 202 datasets allow and finds nothing at all on 40 of them

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: Normalising the licenceInfo of the 202 data items to plain text gives 44 distinct non-empty strings plus the empty one, and 40 items carry that empty value.

What the mapping says: Bus Stops carries 'Caveat : Non-commercial use only' and BMX facilities carries '(c) betterbybike.info 2022. All Rights Reserved.'; both are public items in the catalogue group behind opendata.bristol.gov.uk.

The council's standing open-data page, and the blanket statement the catalogue does not keep. Verbatim: 'Our open data is released under the Open Government Licence 3.0 (OGL 3.0).' Also names the two places the council publishes ('data.gov.uk the central government website' and 'open data bristol our local data website'), and cites an ODI Open Data Certificate whose link returned an ODI server-error page when checked on 25 August 2026.

The licence link points at OGL version 3.

The site's catalogue is one group, c750a490d152430a9aefe9b1fba0ec14, taken from the site item's own catalog definition. Queried 25 August 2026: 'total':210. Paging all 210 records gives the type split (190 Feature Service, 10 Document Link, 4 Hub Page, 2 Web Experience, 2 PDF, 1 Dashboard, 1 Web Map) and the licenceInfo string of every item, from which the licence census in the impact field is computed. Ten sampled records were re-fetched from the per-item endpoint and their licenceInfo matched the search response exactly. The API's own countFields aggregation returns null here, so the census is a full page-through rather than a platform aggregate.

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.
