description	OpenMercantil is an independent public-data project that makes Spanish mercantile information easier to search, understand and reuse. It structures BORME-derived public records and other public sources into company search, registry-event timelines, downloads, methodology notes and a documented API. Its mission is to contribute to open/public data access without profit-seeking intent for citizens, SMEs, analysts, procurement and compliance teams, journalists, researchers and developers. It is not an official registry, certificate service, legal advice or credit-risk rating.
