| historyNote: | 2009-07-14. Generate SKOS encoding of vocabulary from Excel spreadsheet. |
| historyNote: | 2010 11 27 SMR convert identifiers from URN to http URI according to CGI URI scheme. |
| historyNote: | 2010-02-08. SMR Clean up namespace declarations so concept URI's follow CGI URN scheme; concepts have URN, are not document fragments. |
| historyNote: | 2010-02-12 Add narrower relationship links by adding skos:narrower link in Protege, defining skos:narrower as inverse of skos:broader, calculating with Pellet reasoner to add inferred axioms, and using 'file/Export inferred axioms as ontology' in Protege. |
| historyNote: | 2012-02-07 SMR update URI to replace numeric final token with English-language string as in original URN scheme. |
| historyNote: | 2012-02-27 SMR add skos:exactMatch triples to map URIs for concepts in this vocabulary to number-token URIs in 201012 version of same concepts. |
