[DDI-users] [Alliance-experts] quality of metadata

[Mari Kleemola]

Hi Marion,

I agree that your question is an important one, and I'd also be 
interested to hear experiences and thoughts about this. (Wendy - thank 
you for you informative reply.)

WP7 in the Data without Boundaries project is currently studying 
metadata issues like standard selection and usage. My literature review 
revealed many studies about assessing metadata quality (none of which 
were DDI), but not so many about assessing the quality of a metadata 
standard. However, a common agreement for metadata quality seems to be 
"fitness for purpose".

Thanks,
Mari
