| historyNote: | 2010-02-11 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: | 2010-11-28 SMR replace URN with http URI according to CGI URI scheme (see https://www.seegrid.csiro.au/wiki/bin/view/CGIModel/PersistentIdentifiersInGeoSciMLServices) to make versionn 201202 |
| 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. |
