The "Semantic MDM" system is adapted to industrial production and integrated with leading CAD / PDM systems. The system provides centralized storage and global identification of master data. Eliminates duplication and synchronizes objects, information about which is spread over various application information systems. The uniqueness of the system lies in the object-oriented model of master data, which allows first to unify the vocabulary terms, and then, on the basis of a single glossary, create different classification groups with an arbitrary set of characteristics. "Semantic MDM" allows you to operate object relationships and perform a semantic search (SDI patent), which increases the speed of selection of the desired objects.
