Dear group,
I am still quite new to understanding and applying Dublin Core and trying to
get some clarification on a few issues. I have read the basic documentation
on dublincore.org, like the "Using Dublin Core" document, abstract model etc.
We would like to define a specific Dublin Core XML format (or better still:
use an exising Dublin Core format) to be used within a digital library
(non-Dublin Core metadata already exists in various formats from 3rd parties
and would need to be converted). We would like the new format to use the
latest Dublin Core specifics and not have to be changed every couple of months.
Here are the questions:
1) Is it recommended to use the newer DC-DS-XML format instead of the DC-DS
format (since the DC-DS-XML supports the description set as described in the
abstract model)? I don't really see any improvement for us. We will probably
not be using more than one description within a description set. Also the
XSD (http://dublincore.org/schemas/xmls/2008/09/01/dc-ds-xml/dcds.xsd) is
very generic and does not make it possible to validate very much (the
propertyUri, vesURI, sesUri etc. are all specified as xs:anyURI). In the
DC-XML format the properties and encoding schemes are more or less specified
in the XSD (e.g. DCMIType). Will the DC-DS-XML schema be further specified?
Am I misssing something?
2) Can you point me to more practical examples that implement Dublin Core in
XML?
3) I don't understand the concept of a description set containing one or
more descriptions. What is the joint context of these desciptions? Can you
point me to use cases for this?
Thank you very much.
Sybille
