More role-related potential changes to Web Annotation Data Model

A new discussion document is up on GitHub:

   http://w3c.github.io/web-annotation/model/wd/RequireSpecificResource.html

 

This a companion to the roles.html and AnnoLevelMotive.html documents in
same folder.  Comments, corrections, etc. all welcome.  We followed a table
of contents based on roles.html document, but if augmentation with
additional use cases is needed, feel free (just don't delete or renumber any
of the existing items in Table of Contents Section 3). 

 

Issue addressed by this new document: 

You will recall that earlier this month the WG reached a consensus to use a
new property, oa:hasRole, for expressing roles of oa:SpecificResources
serving as Annotation Body or Target.  But a couple of issues summarized in
Section 3.2 of the roles.html [1] document were not formally resolved,
specifically, the 'further considerations' discussed in:

 

*         3.2.1 Require the use of SpecificResource for Bodies

*         3.2.2 Require the use of SpecificResource for Targets

*         3.2.3 Allow hasRole on new EmbeddedTextualBody class

 

This new document captures some of the discussions we had around these
further considerations and illustrates (through 30 examples, each in JSON-LD
and Turtle) some of the implications of our options with regard to these
'further considerations' and with regard to how role might interact with
multiplicity classes (probably an edge case).  

 

At this point, Paolo and Rob are already working on the next update of the
Web Annotation Data Model, so it'll be up to them and Frederick whether to
revisit these further considerations now or wait until after the next
iteration of the Data Model is ready, or at least until TPAC. It may be that
the discussions the WG has already had and the process of updating the model
will clarify things to such a degree that we don't need to revisit these
issues during one of our upcoming calls/meetings - in which case the new
page will just help complete the documentation of the hasRole discussion we
had over the summer. But if more guidance from the WG on these further
considerations is needed at this time, the page is available to facilitate
that discussion.
