[Use Case] Publisher Provided Information for Target

To separate out one point from the cross-formats thread:

As a content publisher, I want to provide information to an annotation
client on how to most effectively annotate my resources, so that the
annotations can all correctly refer to the same resource regardless of the
format, access point, segmentation, language or any other aspect.

At Stanford we have this requirement in multiple ongoing projects and would
[quickly and appreciatively] implement any solution in this space.  In
particular, to make the use case more concrete:

* In the IIIF [1] community, there is the notion of a Canvas [2] which
represents some view of an object such as a page of a book, or the "north"
view of a statue.  The Canvas's URI should be used to annotate this view,
rather than the URI of any specific image, text or other resource, such
that the annotations can be collected together.  In particular, annotating
the image's URI directly results in terrible user experience as the
rendering is done via segmenting the large images and presenting them as
tiles in a zooming interface.   The Canvas can be presented in many
different user interfaces, and thus a cross-platform method of requesting
clients to annotate the Canvas rather than the images is necessary.

* In the Linked Data for Libraries project [3], we have use cases around
annotating bibliographic works (think books).  These works, held by the
participating libraries, are then described in catalogs and other
interfaces.  Annotating the work as it appears in the catalog should have
the annotation also appear when the work is used in a course reading list,
an exhibition, an archive of a faculty member, and so forth.  Likewise,
annotating the work in any of those interfaces should appear in all of the
others as well.
