Composition is decsribed in ebRIM somewhere and its definition is as described in UML. Composed objects are part of another object and cannot live independent of their parent composite objects. In ebRIM 2.5 Classifications, ExternalIdentifiers and Slots are examples of composed objects within a RegistryObject. >(2) Is this covered by our Cursor Support feature? > The issue sent by Mei is not addressed by our Cursor Support feature. The issue is that a client must issue two separate registry requests one to a get a RegistryObject and another to get its ExternalLinks. Where as when a client gets a RegistryObject today all its Classifications are included in same response. I have also found that ExternalLink implementation is trickier because it is handled different from Classifications etc. I tend to be very supportive of the idea of making ExternalLink be a composed object within ebRIM and woudld be willing to do this in our next version (2.6). -- Farrukh > >Joe > >Farrukh Najmi wrote: > > >>There seems to be some glitch with the regrep-comment mailing list where >>we receive exernal comments.
