1.2 para 3.1.7

The <dc:creator> element specifies the name of the person who last
modified the document. The name of this element was chosen for
compatibility with the Dublin Core, but this definition of "creator"
used here differs from Dublin Core, which defines creator as "An
entity primarily responsible for making the content of the resource."


If the semantics are different from dublin core please use a different
element name.
There is no point in diluting DC semantics.
