Taxon Thesaurus File

 

A Taxon Thesaurus File stores a pool of taxonomic items, arranged in a hierarchical way. Each <taxon/> tag can have other nested taxa. This taxa information is essential because in all relevé entries taxon is specified by a name code, and this refers to a taxon name (See Relevé Table File). Synonyms are handled by another code, the internal code. While name code is unique for all taxa, they can share the internal code, so the program can know that they are actually referring to the same biological entity.

Taxon thesaurus files have XML file format. In each file, there is just one <taxon_pool> tag, which can contain an unlimited number of taxa.
