OPC Core Properties -- WAS: My latest draft of OPC

[MURATA Makoto]

Oops, an annotation in
http://dublincore.org/schemas/xmls/qdc/2003/04/02/dc.xsd
provides an answer to my question.

<xs:documentation xml:lang="en">
This is the default type for all of the DC elements. It permits text
content only with optional xml:lang attribute. Text is allowed because
mixed="true", but sub-elements are disallowed because minOccurs="0" and
maxOccurs="0" are on the xs:any tag. This complexType allows for
restriction or extension permitting child elements.
</xs:documentation>

Regards,
Makoto

>> Thank you for clarifying that your intention was to retain the table
>> at the beginning of the Core Properties clause.  That had not been
>> clear to me.
>>
>> I would like to echo a comment made by Rex on yesterday's call that
>> Part 2 is so different from Parts 1 and 4 that it doesn't seem
>> necessary to follow the patterns established there in detail.  To me,
>> what matters is whether the clause is easy to understand.
>>
>> My concern is that following the shape of your suggestion here will
>> make the Core Properties clause much more awkward to read than it need
>> be and than it is now.  For example, for the element "identifier" you
>> would need to look at the table to understand its semantics, to
>> http://purl.org/dc/elements/1.1/identifier to see what Dublin Core
>> actually defines it as (which your increased emphasis on the fact that
>> it is borrowed from Dublin Core seems to require), and to the schema
>> in our Annex to find that it is optional (although your suggested
>> re-write doesn't point there for the borrowed elements).
>>
>> This all seems unnecessarily complex for elements that are almost all
>> of type xsd:string (or the equivalent SimpleLiteral from the Dublin
>> Core schemas our schema incorporates) and optional, and must not have
>> the xml:lang attribute.
>>
>> And for dcterms:created and dcterms:modified, we also need to look at
>> 10.5 Schema restrictions for Core Properties
>>
>> This morning I have not come to a conclusion as to how I would try to
>> address your concerns about missing information without making the
>> clause more cumbersome, but I'd like to encourage you to include the
>> whole clause in your next re-write suggestion to make it easier to
>> review.
>>
>> I need to turn to other matters now.
>>
>>    Thanks.  Caroline
