How to use Project Open Data Metadata Schema guidelines to document and list agency datasets and application programming interfaces (APIs) for hosting at agency.gov/data and currently in use at data.gov

DCAT is an RDF vocabulary designed to facilitate interoperability between data catalogs published on the Web. DCAT-US (used in the Project Open Data Metadata Schema) is based on this W3C data schema.

Further guidance on using the Project Open Data Metadata Schema guidelines to document application programming interfaces (APIs) in data.json files for hosting at agency.gov/data.

A list of FGDC-endorsed standards. Federal agencies that collect, use, or disseminate geographic information and/or carry out related spatial data activities should use FGDC-endorsed standards both internally and through their activities involving partners, grants, and contracts.

To improve the discoverability, usability, and governance of these priority agency data assets agencies shall apply the documenting techniques illustrated below.

ISO is an independent, non-governmental international organization with a membership of 164 national standards bodies. The date field in The Project Open Data Metadata Schema (DCAT-US v1.1) is one example of an ISO standard applied in government.

Provides further background and resources to assist agencies in implementing the Project Open Data Metadata Schema v1.1. Maps fields from the current version of DCAT-US v1.1 to the previous version of the schema (v1.0), as well as other schemas (CKAN API, DCAT, and Schema.org).

Through an open community process, schema.org creates, maintains, and promotes schemas for structured data on the Internet. The schema.org vocabulary is used along with the Microdata, RDFa, or JSON-LD formats to add information to Web content.
