Developed with FileMaker Pro, our "Antic monetary facies" database contains 40,000 records. Its transformation into a collaborative web tool entails a reorganization of the structure by distinguishing between data files, which can be made available at a later date, and the descriptive thesaurus under Opentheso (a web-based thesaurus management tool dedicated to the management of vocabularies), allowing alignment with other thesauri such as those of Nomisma.org, in accordance with the FAIR principles. The originality of this database lies in the fact that it does not start from the coin but from the archaeological site and, if possible, from the contexts of discovery. Then, two levels of entry of numismatic objects are possible either individually (coins, monetary tools, etc.) or by batch via the georeferenced table. Optimized extractions facilitate cataloguing and mapping in WG84, in the European NUTS format thanks to Archéolocalis.
