[Data-modeling] Cross referencing data within CVTs?

[Jeff Prucher]

If I understand what you're asking, you should be able to accomplish this
with a CVT that connects the three types.  So rather than having two
properties ("taxa" and "location") on the souce type, you would just have
one ("priorities" or something) that goes to the CVT. The CVT would have
properties for "taxa" and "location", and when you viewed the "taxa" type,
the "location" and "source" properties would display.

Subject: [Data-modeling] Cross referencing data within CVTs?


I'm interested in cross referencing data within CVTs. Is this possible,
pehaps through the use of delegated properties? For example, I want to
create a list of taxa that are designated as priorities within locations as
specified in a written work (i.e., "priority taxa"&"priority location" as a
property of "priority source") and cross reference it with lists on the taxa
and location types (i.e., "priority taxa"&"priority source" as a property of
"priority location", and "priority location"&"priority source" as a property
of "priority taxa") so that all three lists are populated when any one of
them is filled in. I can't figure out how to do this. Is it possible?
