This workshop on documenting Darwin Core builds throughout each of four sessions over multiple days. Each session will begin with a short presentation providing background, and outlining the scope and goals of the ensuing discussion.

Our focus for the first two sessions will be on three of the most challenging terms: http://rs.tdwg.org/dwc/terms/Occurrence (dwc:Occurrence), http://rs.tdwg.org/dwc/terms/OccurrenceID (dwc:OccurrenceID), and http://rs.tdwg.org/dwc/dwctype/Occurrence (dwctype:Occurrence), as well as additional classes that have been proposed or discussed, and how those classes may affect the definition and scope of what an "Occurrence" is.

This session (Part 1) will focus on how the Occurrence class is currently used, how it was intended to be used, and the differences between them. This will include clarifying term definitions as needed, and identifying where documentation needs to be enriched and improved.
