This page contains links to various documents related to taxon concepts
Disambiguation: this page is NOT about the TaxonConcept Ontology (http://www.taxonconcept.org/) which is compared to other biodiversity ontologies here, diagrammed here, and whose object properties are used in an example of the Darwin Core RDF Guide here.
Summary and links to a thread related to TCS and Taxon Concepts
An email thread from about 2012-11 to 2012-12 which started off as a discussion of the TDWG TCS Standard and ended up on a discussion of the TaxonConcept Ontology of the TDWG Ontologies
RDF representation of a tc:TaxonConcept? instance and its associated reference
This document was produced following an extended email discussion about the meaning of taxon concepts in the context of RDF. It contains (among other things) a diagram which graphically represents a taxon concept. It also includes examples in RDF/XML and RDF/Turtle.
Describing Taxon Concepts as RDF
This is an ancillary document associated with the Darwin Core RDF Guide. The Darwin Core RDF Guide recommends against using the dwc:Taxon class terms to construct taxon concept instances (although they can be used as convenience properties). This document provides suggestions for using terms outside of Darwin Core (i.e. the non-standard TDWG TaxonConcept and TaxonName ontology terms) to construct taxon concept or taxon name use (TNU) instances. This document was informed by the TCS/TaxonConcept ontology thread (linked above) and the TCS-based taxon diagram (linked above).
Notes and email references on the taxon class
This is a (somewhat outdated) page from the Darwin-SW website which contains a lot of links to emails and references to various points of view related to taxa and taxon concepts. There is a somewhat abbreviated version of this here.
