The http://vgenerepertoire.org/ database is automatically extracted from genomes of a variety of species, as summarized by the following figures.
The VBASE2 database was constructed by a very similar process.
At the time the construction was restricted to mouse and human V gene sequences.
The procedure works also on other Ig like sequences.
The extracted sequences were then used to construct the VBASE2 database.
The sequences were automatically annotated (most likely like V-Curate).
