Metadata key for "original file location/name"?

[Allison, Timothy B.]

All,
  Some file formats store the original file location or file name for the file 
itself or embedded documents.  What metadata key should we use for this info?  
DublinCore's Identifier is vaguely on the right track, but not at all 
appropriate.

TikaCoreProperties.ORIGINAL_RESOURCE_NAME?

Should we create a tika-based namespace for this metadata element?  (If so, 
let's use that name space for TIKA-1759)

  Thank you.

          Best,

               Tim
