Decision-2009-12-07_1
Identifier	http://rs.tdwg.org/dwc/terms/decisions.html#Decision-2009-12-07_1
Description	The recommended controlled vocabulary for dcterms:type was changed from a vocabulary of Darwin Core Classes (Occurrence, Taxon, Location, Event) to the DCMI type vocabulary (PhysicalObject, Event, StillImage, MovingImage, Sound, Text, Dataset) to be consistent with the standard use of that term.
Date	2009-12-07

Decision-2009-12-07_2
Identifier	http://rs.tdwg.org/dwc/terms/decisions.html#Decision-2009-12-07_2
Description	The recommended controlled vocabulary for basisOfRecord remains the Darwin Core Type Vocabulary, but the Dublin Core classes StillImage, MovingImage, and Sound were removed from that list as these are to be used as vocabulary for the dcterms:type term.

Decision-2011-10-16_3
Identifier	http://rs.tdwg.org/dwc/terms/decisions.html#Decision-2011-10-16_3
Description	The Dublin Core type vocabulary values StillImage, MovingImage, and Sound have not been added to the list of valid values for Darwin Core type vocabulary pending further insights from the RDF Interest Group about how best to manage basisOfRecord when a record can be "about" more than one subject.
Date	2011-10-16

Decision-2011-10-16_4
Identifier	http://rs.tdwg.org/dwc/terms/decisions.html#Decision-2011-10-16_4

Identifier	http://rs.tdwg.org/dwc/terms/decisions.html#Decision-2011-10-16_5
