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

If you're getting an EPScript error, take a look in the Apache error log - there may be something useful in there.
This is the relevant wiki page: http://wiki.eprints.org/w/EPScript (maybe the 'Language Synopsis' section is the key to what you're doing wrong?)

I'd recommend going down the route (as Tommy hinted at) of making a citation for the document (in ..../cfg/citations/document/myLovelyCitation.xml) and using that e.g.
<epc:print expr="$doc.citation('default')" /> or <epc:print expr="$doc.citation(' myLovelyCitation')" />

If none of that helps, show us what you've got and we may be able to help more!

Cheers,
John

Thanks Tommy,

In principle I see how this should work, however all I¹m getting when I
try to do anything here is an [error in script] output.

For example, in <archive>/cfg/citations/eprint/summary_page.xml, the
documents appear to be iterated through in a set (line 31) with the
outputs handled as $doc.some_function(). This does not seem to correlate
with being able to simply use database names in the output and when I try
$doc.some_database_field() the error is generated. I¹ve also tried simply
using the field as is but to no avail.
