The TDWG Taxon Concept Transfer Schema (TCS; github repo) is still the primary vehicle for transferring information about details of taxon concepts (which are taxonName plus accordingTo constructs), the relationships among them. With the dominance of the GBIF-maintained Darwin Core Archive (DwCA), it would be valuable to be able to express the same inter-taxon-concept relationships in a DwCA.
This repo contains files for defining a DwCA extension for the
TaxonRelationshipAssertion
element of TCS. Note than this element is
just part of the full TCS schema.
