TopQuadrant's TopBraid Enterprise Vocabulary Net™ (EVN) is a flexible, web-based solution for managing semantic information models (taxonomies, business vocabularies, master and reference data) to support a variety of business objectives such as content delivery, search, navigation, data integration and disambiguation of terms.
EVN gives you:
An intuitive graphical user interface
Multi-user support
Editing and review of multiple working copies of a model without affecting the production model until changes are published
Support for unlimited number of custom classes and associated properties
Different access to models and their working copies for different staff members depending on their assigned roles
Change tracking
Data quality rules
Custom reports, saved searches and web services
Integration with third party systems and Linked Data clouds
Support for all relevant W3C standards such as SKOS and RDF
Easy extensibility of features using TopQuadrant's TopBraid platform
EVN lets you create, edit, and use vocabularies, ontologies, and content tag sets.
Vocabularies are datasets that are based on SKOS, the W3C standard and ontology designed for the needs of people managing taxonomies, thesauruses, and other controlled vocabularies with associated metadata.
Ontologies are non SKOS-based datasets. Some ontologies may contain schema-level information only—that is, definitions of classes and properties. (The W3C's SKOS ontology is one example.) Other ontologies may contain data as well as schemas. Using imports, one can combine ontologies with SKOS-based vocabularies.
Content tag sets are datasets that link information in one dataset with the information in another one. Typically, one of the datasets is a vocabulary whose values are used to tag information in another dataset. The dataset containing tagged items often comes from a content management repository such as SharePoint. In this case, the information being tagged may not be stored in EVN, but rather accessed by EVN through a real-time connection to another store such as a content management system. When creating tags, any property or a set of properties may be used to link vocabulary values to content items for tagging. See Using EVN Tagger for information on creating tag sets.
