Release Notes: TopBraid 5.2

Detailed List of Changes:


TopBraid 5.2 marks the first release of TopBraid Enterprise Data Governance (EDG). TopBraid EDG lets users govern and connect a broad set of critical business assets such as business glossaries, reference data, technical metadata, policy and lineage models. With this, Reference Data Manager (RDM) is now one of the available EDG packages. Other packages include Business Glossaries, Basic Data Architecture and Extended Data Architecture. Users have the flexibility of starting with any of the packages and adding more as needed. Enterprise Vocabulary Net (EVN) remains a standalone product for users interested only in managing taxonomies and ontologies and using them for content classification and search enhancement. Alternatively, users with broader governance goals, that span structured and unstructured data, can use EVN as a package under EDG and combine it with other EDG packages. Other enhancements include:

  • In 5.2, EVN and EDG users have additional triple store options – Apache Jena TDB and MarkLogic databases. At the same time, load performance of SDB has been improved, memory usage lowered and server startup times reduced. SDB performance improvements and the need to fix a long standing issue with proliferation of prefixes on export, required a modification of the SDB schema. Users upgrading to release 5.2 will need to follow a provided data migration procedure – See our 5.2 data migration release notes.
  • Release 5.2 offers many enhancements to the user interface of EVN to allow for a more consistent, intuitive user experience. Also included is a major technology upgrade to the JQuery libraries.
  • SHACL implementation has been updated to stay in sync with the development of the standard and SHACL support is now available in EVN and EDG – previously only in TopBraid Composer.
  • 5.2 also provides a technology upgrade with the move to Apache Jena 3.1 and RDF 1.1.
