Guide: Question re annotations

I am trying to write up an additional annotation paragraph for the
Guide.  And I don't fully understand our solution. 

Consider the use of the Dublin Core tag, 'creator'.  I assume I should
provide the following, either in my document or via some import.

 <owl:AnnotationProperty rdf:about="&dc;creator"/>

What are the consequences of its absence?

If the value of the property is a literal, do I need or should I
provide the following?

 <owl:DatatypeProperty rdf:about="&dc;creator"/>

Final question.  Given

 <WineGrape rdf:ID="G1">
   <dc:creator rdf:resource="M.K.Smith"/>
 </WineGrape>

 <WineGrape rdf:ID="G2">
   <owl:sameIndividualAs rdf:resource="#G1"/>
 </WineGrape>

Does this entail 

 <WineGrape rdf:ID="G2">
   <dc:creator rdf:resource="M.K.Smith"/>
 </WineGrape>

Thanks.
