P1: Annotation metadata is flexible

Metadata is like a nutrition label in a cereal box.
RDF metadata can be easily merged and presented in different ways
e.g. metadata from the cereal company, a nutrition counselor, and neighborhood children.

Sample annotation:

<a:Annotation about=“http://…/annotation/3ACF6D754”>
  <dc:creator>Marja</d:creator>
  <dc:title>This is great</d:title>
  <a:annotates rdf:resource=“http://demo.org/whales.html” />
  <a:body rdf:resource=“http://…/body/postit.html” />
</a:Annotation>
