Named virtual corpora (VC) are system corpora that are automatically loaded by Kustvakt from a specific location. New corpora will be stored in a database. Existing corpora will be updated (i.e. the JSON definition). Then, they will be also cached on disk.

To activate the function, the location of the named VC must be configured in a Kustvakt configuration file, for instance:

krill.namedVC = data/vc

There are multiple ways to initiate the function:

1. By running a Kustvakt jar or starting the Kustvakt server.
2. When Kustvakt is running, it is possible drop a new or updated VC at the named-vc location, and call the load-cache name vc web-service for admin.

To update existing named corpora, they can be simply dropped at the named-vc location. Then, an admin can either restart the Kustvakt server or call the load-cache name vc web-service.
