Using OPEX and PAX for Ingesting Content
Preservica has developed the concept of an OPEX (Open Preservation Exchange) package, a collection of files and folders with optional metadata, as a way to organise content into an easy to understand format for transfer into or out of a digital preservation system. Although we have created it, we hope suppliers of digital content to be preserved, and other digital preservation systems, will use it due to its simplicity.

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.

Using Python with the Preservica Entity APIs (Part 3)
In this article we will be looking at API calls which create and update entities within the repository, some calls to add and update descriptive metadata and we will also look at the use of external identifiers which are useful if you want to synchronise external metadata sources to Preservica.

Using Python with the Preservica Entity APIs (Part 2)
In my previous article on using the Preservica Entity API with Python we looked at creating the authentication token used by all the web service calls and then showed how we could use the token to request basic information about the intellectual assets held in the Preservica repository.

Using Python with the Preservica Entity APIs (Part 1)
The Preservica Entity API provides a set of Restful web services to allow users to interact with the Preservica repository. The services allow both the reading and writing of metadata attached to both digital assets and their parent aggregations or collections. The API also allows read access to the digital content within the assets.

Getting started with Preservica access tokens
Preservica maintains a number of API end points that allow third party systems and external processes to be used to automate such tasks as searching, ingesting and exporting content, as well as updating metadata in Preservica, to name but a few.
