[protege-discussion] Protégé OWL issues

[Morozov, Anna (DWLBC)]

Hi all, 

We are using the Protégé 3.2. 
We have come across the following issues: 
·	If a Relation is defined (without Range or Domain being specified) and then subsequently used in association with a specific Class (complete with a specification of the Range to which the operator some applies) erroneous data can be entered when specifying an Instance.  In this case, an Instance of ANY Class in the ontology can be specified, not just those in the range specified when the Relation was applied.

·	Complex NESTED specifications do not seem to be possible and consequently, when entering details for a specific Instance (when the parent and parent's parent details are ideally echoed as the nominated Relation Instance is selected) the data entry can easily go astray.

Any comments? Thank you.

Anna
