Topic map conversions of Gellish ontologies

Revision as of 11:05, 18 April 2009

Gellish, also known as STEPlib, is a controlled vocabulary used especially in engineering to specify products, facilities, and processes. Gellish vocabulary contains concepts and named binary relations between concepts. Relation in Gellish is called also a fact. You could think of the fact similar to a RDF triplet. Addition to the triplet, a Gellish fact contains meta data describing fact's discipline, definition, date of creation and modification, signature (originator), reference and status.

Gellish ontologies were converted to topic maps with Wandora's Gellish ontology extractor (not available in current Wandora release). Original Gellish ontologies (version 8.0) were downloaded from SourceForge March 2009.

All converted Gellish ontologies are available as Wandora project files and zipped XTM 2.0 dumps.

Conversion details

Topic Maps conversions use Gellish excel spreadsheets (See example below).

First, these Excel spreadsheets were converted to tab delimited text. Then, these tab delimited texts were extracted using Wandora's Gellish ontology extractor. The extractor was programmed specifically convert these tab texts to Topic Maps format.

The conversion process reads the tab text file one line at a time and converts the line to a fact topic, and consequently concept, date, etc. topics.

Below is a screen capture of Wandora with Documents ontology. Current topic represents Gellish fact that says HTTP open SSL is a synonym of hypertext transfer protocol over secure socket layer. Fact's discipline is information management and fact is signed by Andries van Renssen.
