I'm trying to clarify for the OEB group the encoding (upper/lower case) of DC elements. They have had in their document the following: dc:Creator i.e. lower case "dc" uppercase 1st letter of element. I'm not sure where this came from; they based it on DC 1.0. There must have been examples at that time like this. We have definitely done some about shifts on this. Seems that the encoding in HTML is: DC.Creator i.e. upper case "DC"; uppercase 1st letter of element RFC 2731 (encoding DC in HML): DC.Creator Using Dublin Core (Diane's User Guide) also shows it this way. In the RDF/XML examples in Using Dublin Core it says:. dc:creator (all lower case) And this is what Andy has in his document for XML. Is this correct and what should be recommended (the different conventions in HTML and XML)? Question: Andy's document has element refinements as follows: <dc:date> <dct:available> Not to be dense, but what is "dct"? Why isn't it "dcq"? I'm sure it's something I must know and I'm just having a Monday morning lapse. Do we still consider the recommendation in "Recording qualified Dublin Core in HTML meta elements" (http://dublincore.org/documents/2000/08/15/dcq-html/) the recommended way? This uses: DC.Date.created where it uses the dot syntax and lower case for the first letter of the element refinement. (All these variations between HTML and XML are very confusing.) The OEB people will be very upset about these syntax issues, and will probably not want to change their document because they will say it will break existing implementations. Not sure how I'll convince them otherwise. Thanks for doing this, Andy.
