Cognatrix

Cognatrix is a native (Cocoa) application for creating and maintaining monolingual thesauri, dictionaries, taxonomies or similar information structures such as Definitions Registers. Cognatrix supports Preferred Terms, Variant Terms, Facets and user-defined Attributes for implementing concepts like "audience" or "classification". Terms can be created singly or imported in bulk via drag-and-drop. Cognatrix's multi-document architecture also permits drag and drop of terms between thesauri. Relationship types include Broader & Narrower (including poly-hierarchical), Related Term, Use & Use For, Synonym of & Synonym For and Obsoletes & Obsoleted By. Broader & Narrower relationships are created automatically between Preferred Terms according to their relative positions in the taxonomy (other relationships are created manually). Straightforward design with one window per thesaurus containing two tabbed views. Tree View is where you create and edit terms, and rearrange your taxonomy via drag-and-drop. List View is used for reports. No design limit on number of terms (education version limited to 500 terms). No design limit on number of user-defined fields (eg "Definition" and "Scope Note"). Term names and user-defined fields can hold up to 2 gigabytes of Unicode data. User-defined fields can also contain active URLs. No design limit on number of user-defined attributes. No design limit on number of relationships. No design limit on hierarchical depth. Cognatrix generates XML in Zthes or Cognatrix formats for data interchange. Also generates publication-ready HTML using customizable templates. An extensible helper application (CognatrixImporter) can import thesaurus data in a number of XML formats. Cognatrix is completely self-contained and does not rely on an SQL database; just drag Cognatrix into your Applications folder and double-click.
