Using the PAR API to create Custom Migrations

Since the release of v6, Preservation Actions within Preservica have been defined and controlled using a PAR (Preservation Action Registries) data model. To facilitate this, Preservica’s registry also exposes a PAR API to allow a full range of CRUD operations on this data. This API also makes it possible to write new migration actions using Preservica’s existing toolset, for example, to introduce re-scaling to your image/video migrations, or to get different output formats altogether. In this article, we will introduce the key concepts in this data model, explain how Preservica uses and interpret them, and introduce the API calls required to create your own custom actions. We will do this by a worked example, using ImageMagick to create a custom “re-size migration” for images.
