Inserting a metadata UID into a document?

I would like to insert the UID of a metadata value into a document when the document is generated.
Eg. A document has metadata myMetadata=myValue, and myValue's UID from MetaTagger is 123. How do I insert "123" into the document?

I was looking into perhaps making a command line call from the template, to use MetaTagger's iwqueryvocab or iwmetadata CLTs to make a query and parse the UID from the results, but it sounds ugly.

Is there some simpler way?

I want to create a link in a document that looks like href="myscript.asp?uid=123"
I want to use the UID because the actual value is very long.

You would probably need to write a script for that, however there may be another
option.

If you are on Unix, there is a section in the Admin Manual call RCS Macro Expansion

This will expand in your doc a number of RCS like variables, one of them may be sufficient
for you to use, maybe put UID into the comment, etc.
