Re: Proposal to modify Classifications in ebRIM

>To go the other direction it works as well. One can issue a
GetClassificationTreeRequest and give it  ClassificationNode reference to
any
node in any scheme, and a integer depth parameter as input. The resulting
GetClassificationTreeResponse will have the complete linked tree for the
requested sub-tree in the scheme scheme as a single XML document when the
depth
specified is negative. Othewise it return descendent nodes upto specified
level
of depth. If the specified node is a root of a scheme then the entire scheme
can
be retrieved as well.

Yes

with a query like below:

>SELECT FROM ClassificationNode WHERE path = ‘/Geography/Asia/*’

This seems to offer no functionality over the above as Asia is a specific
node, and * seems to indicate all entries one level down from this. I was
thinking more along the lines of Europe[5,15] to select a specific set of
nodes, such as those forming the EU.
