ResourceMetaData "uuid" field

[Richard Eckart de Castilho <ec...@ukp.informatik.tu-darmstadt.de>]

Hi everybody,

I noticed there is a UUID field in the ResourceMetaData interface. What is it good for? Is that something that is set at dynamically at runtime or is that something somebody would actually want to configure statically in a descriptor? 

Cheers,

-- Richard

This seems to be unused, except for (perhaps) making every resource have a
unique-ness (e.g., be not "equal" to another resource).  The code has several
place where if the value of this field is null, it sets it to a UUID.

But there's no use that I can see.

The "reference" documentation does not mention this.  And I couldn't see a
reference to this in the OASIS UIMA spec.
