[tdwg-tapir] Updates and plans

["Markus Döring (GBIF)"]

Dear all,
I would like to discuss the optional bits of TAPIR capabilities again  
in the light of service interoperability, especially when dealing with  
TAPIR lite.
Do we really need to have so many optional capabilities for TAPIR? I  
do firmly think this is causing more problems than benefits and would  
prefer more mandatory capabilities. In particular I think TAPIR model  
support should be the lowest common denominator and not only templates  
as it is currently for TAPIR lite.

Do the following capabilities really need to optional?

- the inventory and search operation is optional. Is there a need for  
services not supporting them?
- any need for inventory operations not to support anyConcept?
- search operation should mandate at least 1 output model support
- cant concept, literal and parameter expressions in filters be  
mandatory?
- likewise cant logical operators and equals comparisons be mandatory  
filter parts? what about greaterThan and lessThan?


regards,
Markus
