[dcc-associates] expressing certainty in PREMIS

[Swithun Crowe]

Hello

I'm looking at using PREMIS (http://www.loc.gov/standards/premis/) as the 
technical metadata vocabulary for an archiving project. I plan to use FITS 
(http://code.google.com/p/fits/) as the tool to generate technical 
metadata, and then transform the output to PREMIS with XSLT.

FITS uses various tools for generating metadata (JHove, DROID, NLNZ 
metadata extractor, Exif tool etc.). Sometimes these tools disagree with 
each other, or they produce conflicting or uncertain results, or only one 
tool can provide a piece of information. FITS outputs these conflicts and 
levels of certainty.

But I am unsure of how to translate this into PREMIS. An attribute 
@certainty, say, would be nice. But the schema wouldn't allow it. Has 
anyone found a way round this?

Would repeating elements like 'format' be a good solution to conflicting 
format identifications?

Swithun.
