The database is progressively enriched with new data sets, processed and integrated in successive batches. The data is in xml-ead and xml-tei format, after a phase of alignment with existing data and enrichment according to authority records (Rameau, VIAF, SUDOC, IdRef, etc.).

Here are the main evolutions of the successive versions of the World Horse Library, as well as the main lines of the roadmap for future developments.
