How Washington publishes open data

Washington maintains a central Open Data portal for municipal datasets and APIs, operated with guidance from city technology leadership. The portal lists dataset metadata, licensing, and endpoints for API access; agencies publish data according to portal procedures and data standards overseen by the Office of the Chief Technology Officer (OCTO). See the portal and OCTO program pages for agency-specific instructions and API documentation Open Data portal[1] OCTO[2].

Publication standards and API basics

  • Metadata requirements: title, description, update frequency, license.
  • Formats: machine-readable formats such as CSV, JSON, GeoJSON where applicable.
  • Access: APIs are typically open without per-request fees unless otherwise stated by agency policy.
  • Privacy: datasets must be reviewed for personally identifiable information before publication.

For the city-level open government policy and any formal open data guidance, consult the District's published open government resources Open Government pages[3].

Penalties & Enforcement

The Open Data portal and OCTO provide policy and technical oversight, but explicit monetary fines or statutory penalties for failing to publish datasets are not listed on those pages. Where penalty amounts, escalation, or specific sanctions are not present on the official portal or OCTO site, this guide indicates that the figures are not specified on the cited page and directs readers to contact the enforcing office for enforcement policy.

  • Fines: not specified on the cited page; contact OCTO or the issuing agency for details.
  • Escalation: not specified on the cited page.
  • Non-monetary sanctions: agency orders to remediate, removal of portal privileges, or administrative review are possible but not itemized on portal pages.

  • Appeals and review: not specified on the cited page; inquire with the enforcing office about administrative review timelines.
If the portal lacks a stated penalty, request written clarification from the agency.
