The Petrae database is a system for the recording of Latin and Greek inscriptions developed at the Institut Ausonius, which collects epigraphic texts from the various regions in which its researchers and collaborators are active.

Each record produced has the text of an inscription in both an uppercase and lowercase version, accompanied by metadata on all aspects of the monument, including support, fragments, epigraphic fields and text elements (dating, paleography, critical apparatus, translation, notes).

The entries are connected to the index and general bibliography and represent an important graphic documentation. Digital headings and keywords accompany other free writing. The database contains entries published (books or articles) in the Petrae format.

As a result of this effective system, each record presents recent information that has been validated by researchers who have scrutinized the data.
