Between 1998 and 2000, the Lexicon Working Group produced documents and findings about the GenTech Genealogical Model. By a merger in 2002, GenTech became known as NGS GenTech, division of The National Genealogical Society (NGS). Particular documents from 1998 and 2000 by the Lexicon Working Group are available from the NGS Internet site. The documents available from NGS GenTech include a 101 page model description/ discussion and, separately, two diagrams of the model. The diagrams are a representation of the GenTech (a) data model and (b) process "map." The Lexicon/GenTech materials can be downloaded (pdf, MS Word 97 and Visio format).
