Preservation Action Registries

PAR is an open source project hosted by the Open Preservation Foundation.

This github repo contains a Data model (defined in a set of json schemas) and API definitions (defined using Swagger) to facilitate sharing and exchange of digital preservation best practise within the community and between presevation systems.

There is another github repo containing par examples that show how the par json schemas can be used.

Current Version

The current release of PAR is v1.1.

There is a separate project called par-wikidp which contains a reference implementation of par v1.1. This is an API server that pulls information out of wikiDP and makes it available using the PAR api.
