New ebRS Section 8.2.2, RegistryEntryQuery

[Len Gallagher <LGallagher@nist.gov>]

Regrep,

During the past few weeks the "regrep-query" team has been discussing ways 
to enhance the Filter Query mechanism in Registry Servcies (cf ebRS Section 
8.2) to accommodate revisions and enhancements in ebRIM, to combine Browse 
and Drill Down Query with Filter Query, and to accommodate classifications 
by external classification schemes. I volunteered to produce several 
proposed new sub-sections of ebRS Section 8.2, Filter Query.

Attached are two short PDF documents:

   1) Proposed new text for ebRS Section 8.2.2, RegistryEntryQuery

   2) A UML sub-model of ebRIM used to influence the specification of 
RegistryEntryQuery.

The UML sub-model is consistent with the UML model in ebRIM, but it is not 
intended to replace any of the diagrams in that specification. It simply 
exposes the class associations deemed important for RegistryEntryQuery.

The RegistryEntryQuery specification assumes the addition of several new 
methods to the Classsification and ClassificationNode classes in ebRIM, 
especially a getPathDepth() method to calculate the depth of a node in the 
classification tree and a getPathElements() method to better expose the 
complete parentage of a classification node. If those methods are not added 
to ebRIM, then those elements in the query can simply be deleted.
