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
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.
Comprehensive Knowledge Archive Network (CKAN) is a powerful open source data management system that makes data accessible by providing tools to streamline publishing, sharing, finding, and using data. The Data.gov catalog is based on CKAN, a technology that powers many government open data sites. Inventory.data.gov is a separate instance of CKAN hosted at GSA on the same infrastructure as the Data.gov catalog.
JSON Validator is used to check your agency’s data.json against the required federal metadata schema. This web-based tool provides three ways you can validate data.json: by validating a public URL, uploading a json file, or pasting the raw JSON into the form.
