I am still somewhat puzzled why TDWG seems so opposed to adopting anything that comes from outside a small click? I was thinking that it would be best to create a separate class that can be used for populations of a species. This would require adding an additional tag to the TaxonConcept Species Concept Model, which currently includes several tags like entities http://lod.taxonconcept.org/ses/mCcSp#Species <- The Species Concept for the Cougar See http://lod.taxonconcept.org/ses/v6n7p.html HTML http://lod.taxonconcept.org/ses/v6n7p.rdf RDF http://lsd.taxonconcept.org/describe/?url=http%3A%2F%2Flod.taxonconcept.org%... Base View (http://bit.ly bit.ly/gMFqR1 The model mints URI's for the following related entities. See RDF. or KB View http://lod.taxonconcept.org/ses/mCcSp#Image - An image of a Cougar http://lod.taxonconcept.org/ses/mCcSp#Occurrence - An occurrence of a Cougar http://lod.taxonconcept.org/ses/mCcSp#Individual - An individual Cougar http://lod.taxonconcept.org/ses/mCcSp#Taxonomy - A Basic Taxonomy for the Cougar, one alternative among many potential classifications http://lod.taxonconcept.org/ses/mCcSp#NCBI_Taxonomy - The NCBI Taxonomy for Cougar, or starting at the lowest available clade http://lod.taxonconcept.org/ses/mCcSp#OriginalDescription - The Original Description of the Cougar, ideally with links to the PDF or BHL URI. Here is how a subset of these would relate to the new #Population Tag and related semantic entities. This tag is used an individual organism that that is an instance of the species concept pecies concept RDF. This allows you to refer to a individual cougar in a way that is separate from the concept of cougar and retains links to other data relating to that species concept. <txn:SpeciesIndividualTag rdf:about=" http://lod.taxonconcept.org/ses/v6n7p#Individual"> <dcterms:title>A Tag for individuals of the species concept Puma concolor se:v6n7p</dcterms:title> <skos:prefLabel>A Tag-like resource that is used to label individuals of the species concept Puma concolor se:v6n7p</skos:prefLabel> <dcterms:identifier>http://lod.taxonconcept.org/ses/v6n7p#Individual </dcterms:identifier> <dcterms:description>A lightweight tag that can be used to label individuals of this species.
