IPT version 3.3.2 DwC MaterialEntity contains 180 properties

[CecSve]

In the latest version of the IPT, administrators can add the Darwin Core Material Entity extension to map to. There are a couple of issues:

• the version says 30 April 2023, but I believe it replaces Darwin Core Material Sample after the recent TDWG ratification? If so, other extensions show as deprecated and have information about the successor, but not this one
• it is possible to map 180 properties (all Event, all Taxon terms, etc.) in the extension, although only 17 seem to exist in the standard
• it is unclear whether mapping this extension or other extensions, or terms within them, means that the information will be indexed and visible/searchable on GBIF.org (separate issue logged)
