@esabol : thanks for your typo corrections .
A question for you :
What is the MIME type you typically use for describing data sets in Obscore , in the access_format column ?
if not in ObsCore , which MIME type would you use to publish or search a high energy data file in your favorite archive ?

Many thanks for your feedback .

All of our ObsCore entries use DataLink, so our MIME types are

application/x-votable+xml;content=datalink
