I (think that) I like Stian's "modularity" view as it applies to one
of our central uses of annotation of data with  data quality control
assertions.  In some of those cases, the Target is a database and the
SpecificResource is the data returned by a query. The annotations
assert Internal inconsistencies or missing data within that set (the
"circled" data records) and those returned by another query (the
"blue" data records).

In one use of the above we do something about which I do not see many
analogies for documents.  That is, we sometimes regard the above
situation as being assertions about \all/ data with a schema for which
the queries make sense. At the moment, only one thing comes to mind
vaguely related to that for documents. This would  would be assertions
about the failure of recommended semantics of document structure.  For
example, in English composition at school we are taught that the first
sentence of a paragraph should always introduce the topic of the
paragraph, and each paragraph should have a single topic.  Every
annotation asserting a failure of that principle can probably be
asserted in OA in a single "modularization" sensu Stian.
