It would be nice if the Document Information returned when searching records contained a definition for abbreviations.
Example: Originating System VR (vital records? from where?)
Also: Originating System EASY and ODM
@LDS Search Test
Take a look at this "Knowledge Article" in 'FamilySearch':
Where it indicates, among other things:
Extraction Administration System, a method of indexing record collections before the current indexing program.
Ordinance Data Management, a database of ordinance information.
I have 'seen' that "VR"; and, if I recall, "Vital Records" - Batch Description
That Said ...
I also found this:
Vital Records Index, especially those sets produced on CD by FamilySearch by the professional-level extraction process
Not quite the same; but, similar.
VR is the same as VRI or Vital Records Index which basically contains all the extracted records from the old extraction program which never made it into the International Genealogical Index (IGI).
Since I have never seen IGI as originating system, I suspect that IGI and ODM are basically synonymous.
So it appears that Originating System has nothing to do with where the records came from, but is a notation of which extraction/indexing program was used to create the record set.
