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-710ef2bd1602f61b quantitative

Transport for NSW's Open Data Hub has published live GTFS-realtime feeds — vehicle positions, trip updates and alerts — for Sydney's trains, buses, ferries and light rail since 2016, with feeds refreshing about every 15 seconds under a CC BY 4.0 licence.

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The two TfNSW dataset records identify the GTFS-realtime feed types, modes and 2016 creation; TfNSW's developer guidance documents an approximately 15-second refresh interval, and the data licence applies CC BY 4.0.
Caveat: The TfNSW portal returned 403 to automated fetches in this pass; search-indexed portal text and the prior Sydney review support the mapping.

Claim 2 clm-7fa422f682c65481 quantitative

The programme reports more than 51,000 active users and 11,300 registered applications

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The NSW Government case study reports more than 51,000 active users and 11,300 registered applications for the Hub.
Caveat: Operator-reported platform counts; ‘active users’ is preserved rather than recast as registered developers.

its trip-planning examples include TripView and Google Maps.

Published field: snippet · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport

Caveat: The portal returned 403 to automated retrieval in this pass; the mapping remains explicitly unreviewed.

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.
