[EP-tech] Re: Summary page - available metadata

Okay, that’s working great - extrapolating out from this, how would I then
tap into other data? For example, we’d like to output a list of editors
onto the abstract page if the EPrint is a book. I know how to do the
conditional check for the type, I can see how to iterate through a number
of objects, but I’m not sure how to retrieve those objects. Once we have
them, I then presume that the theory is the same of using a citation
template with relative fields to extract data from the database.
