TopBraid Enterprise Data Governance (EDG) is a data governance platform built on RDF knowledge graphs from TopQuadrant. It is available in four modular packages: Metadata Management, Reference Data Management, Vocabulary Management, and Business Glossaries. The former three provide specialist capabilities for governing technical metadata, reference data, and taxonomies and ontologies, respectively. Business Glossaries adds its namesake, and is included in Metadata Management. Several add-on modules are also available. TopBraid Tagger and AutoClassifier, which provides automated tagging and classification, and TopBraid Explorer, which offers read-only access at a budget price per user, are particularly notable.
