Until 2018, the 2 argument predicate was the main entry point (as the date and version didnot match- but the latter was derived off the date).
As of 2018 bio_db_repo_version/1 is the main entry point and bio_db_repo_version/2 is provided for compatibility with other stoics.org.uk packs.
Currently:
?- bio_db_repo_version(V,D). V = 25:9:26, D = date(2025, 9, 26).
Previously:
bio_db_repo_version(19:2:11).bio_db_repo_version(18:11:27).bio_db_repo_version(18:11:23).bio_db_repo_version(18:3:30).bio_db_repo_version(17:10:13,_).bio_db_repo_version(17:10:8,_).bio_db_repo_version(17:3:3, date(17,3,4) ).bio_db_repo_version( 16:9:10, date(16,9,11) ).bio_db_repo_version( 0:4:28, date(15,4,28) ).bio_db_repo_version( 0:9:14, date(16,9,14) ).*/
