Subject [greenstone-users] Using a controlled list for Subjects in Qualified Dublin Core
In-Reply-To (6667)
Hi,
I'm trying to build a collection containing a number
of documents. We want to have a controlled list of
Keywords from which authors can choose when they add
documents to the collection, preferibly using the GLI.
Is this possible?
I am using the lastest release of Greenstone (2.53)
and tried adding an <OptionList><Value> element (I've
included the code below), but the value doesn't show
and I can't seem to find any documentation on how to
accomplish this.
Also, I had to edit the DTD for Qualified Dublin Core
(in ../gli/metadata/) quite a bit to get it to
validate in XML Spy...
Any help is greatly appreciated!
