feature request #1580
Updated by Andreas Müller over 2 years ago
Taxonomists often do not know if a (type-)specimen really exists in a given collection or not. A flag "presenceInCollectionDoubtful" (?) could help handling this information. Sometimes also some more information is available such as "lost" or "probably lost". This information may also go into an own attribute in the DerivedUnitBase class. Maybe both attributes can be merged. An alternative way to handle this kind of information is to use annotations, extensions and/or marker. Diptera are a concrete use case for this kind of information (see #362). see also #2506
