In this post I'll give you a summary of what APIs we have in Preservica 6.3, and what new features you might be interested in. If you've been using Preservica for a while and just want to know what changed, you can look for the relevant paragraph at the end of each section, and for more details, you can look at the release notes from the three versions (6.2.1, 6.2.2 and 6.3). If you're new to the Preservica APIs then you can use the whole article as a reference.
Brian Thomas, Electronic Records Specialist at Texas State Library and Archives Commission (TSLAC), considers why they started using Preservica APIs, the most common ways these are used and the steps they use to work out new processes.
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.
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.
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.
