[gate-users] Jape rules matching annotation types with labels including colons [SEC=UNCLASSIFIED]

[Parker, D. <dav...@ds...>]

UNCLASSIFIED 

Hi 

Gate can successfully load XML documents with namespaces, but it would
appear that one cannot successfully write JAPE rules to match the
Original markups.

For example, the following original and GATE documents can be
successfully loaded, and creates the expected Original markups, but it
would appear that one cannot write rules that have input Types of the
form dc:title or dc:description

Is it possible to create rules to match type names with embedded colons,
such as Dublin Core elements.  The JAPE parser appears to object to the
Input statement of a Phase having typenames with embedded colons. It
raises the gate.jape.JapeException: Batch: error parsing transducer:
Cannot parse a phase in file ....

Cheers 

David
