This directory contains the zipped flat file releases of the 
NCI Thesaurus and the CTRM vocabulary.


Ctrmv6_5.zip file contains version 6.5 of the CTRM (Core Terminology 
Reference Model), with editing completed through July 3, 2002.

ThesaurusV1_0.zip contains the NCI Thesaurus with editing completed 
through July 22, 2002.



The content of each file is in tab-delimited format.  The fields are:

concept code <tab> concept name <tab> concept parents <tab> synonyms <tab> definition

If a "concept parents" or "synonyms" field contains multiple entries, these 
are pipe-delimited.  The first entry in the "synonyms" field is the 
preferred name of the concept.  The "definition" field contains only
one definition if more than one definition is associated with the concept;
not all concepts contain definitions.
