Dallas has published over a thousand city datasets since 2013 — but there is no blanket open licence behind them, just a Terms of Use agreement governing reuse.

The City of Dallas launched its open-data portal, now at dallasopendata.com, in November 2013 on the Socrata platform, publishing city records spanning 311 service requests, police incident data, budget data and permitting activity. As of this review the portal's own catalog API reports 1,087 published datasets. Dallas has not adopted a blanket open licence such as CC0 or a public-domain dedication for the catalog — reuse is instead governed by a Terms of Use the city describes as "a legal agreement between You and the City of Dallas", so individual datasets' reuse rights are not uniformly guaranteed the way they are on portals with a stated default licence.

Live 📅 since 2013

📊 Impact

1,087 datasets published on the Socrata-based catalog, self-counted via the portal's own catalog API at the time of this review.

🎓 Lesson

The difference between a licence and a Terms of Use is not a formality. A licence is a grant that travels with the data and cannot be withdrawn from a copy already made; the Dallas terms are a contract the city writes and can rewrite, and the version on the portal was published in 2016 and last touched in 2021. What a reuser may do with a Dallas dataset therefore depends on a document rather than on the dataset, and nothing in the catalog records the answer dataset by dataset.

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.
