TopQuadrant's TopBraid Enterprise Vocabulary Net™ (EVN) is a flexible, web-based solution for managing semantic information models (taxonomies, business vocabularies, content tagging, etc.) to support a variety of business objectives such as content delivery, search, navigation, data integration and disambiguation of terms.

Available Vocabulary and Asset Types

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 Tagger User Guide for information on creating tag sets.

Documentation

The EVN Terminology and Getting Started pages introduce some of the key concepts and features of EVN.

The  EVN Adminstrator Guide : Multiple pages cover the Installation and Integration of the EVN application server and the Administration of the application's user environment and features.

The  EVN User Guide : Multiple pages cover the details of editing and managing the various Asset Collections, along with their governance and workflows.

The  EVN Developer Guide : How to customize aspects of the application, data preparation, and services, including use of the development environment TopBraid Composer – Maestro Edition (TBC-ME).

Documentation Conventions

Names for user interface widgets and menu options are presented in a style like this.

Where exercises require information to be typed into EDG, a monospaced font is used.

When describing capabilities and user interfaces that work the same for ontologies and reference datasets this guide uses the term Vocabularies to mean both ontologies and reference datasets.

Exercises and required tutorial steps are presented like this:

  1. Execute the first step.

  2. Then, execute the second step.

  3. Here is the third step to carry out.

Tips and suggestions for using EVN are presented like this.

Potential pitfalls and warnings are presented like this.
