The FAIR principles are meant to ensure that (corpus) data can be reused for other purposes. But reusability is typically only considered from the perspective of static resources, while nowadays, many important data sources are regularly updated.
In this paper, we will show how creating one resource from another using the API of both sides can make for a dynamic setup in which two resources can be kept in-sync programmatically, even in the case of changing source data. We will illustrate this by pulling data from the Dracor corpus via the API, and uploading and processing data into a TEITOK corpus also via the API.
In the setup in this paper, syncing is done by periodically checking for modified data, but in a more involved integration, an on-update trigger could be used on the source side.
