Open Annotation – where do we go from here?


Annotating, the act of associating one piece of information with one (or more) other piece(s) of information, is an active part of the way that researchers work with data and has been the subject of discussion at several publishing related conferences recently. We all do it in the physical form for ourselves, increasingly we add comments to documents electronically and these become part of the open electronic record. On 9th April and 6th May Phase III of the Open Annotation Data Model & Ontology was published and rolled-out by Open Annotation Community Group at events at Stanford University and University of Maryland. These events will be followed by a third event to be held at the University of Manchester on 24th June 2013 when implementers, developers, and information managers will be able to see existing annotation services which have been built using the open annotation model.

Developed by the Open Annotation Community Group (“OA” not to be confused with Open Access) this is one of a number of initiatives addressing how annotation fits in with online publication of research through online journals and books, repositories, databases and social networks by working towards a common, RDF-based specification for annotating digital resources. Paolo Ciccarese, Chair of the Group and a name that recurs through the various meetings came to my attention at the BTPDF2 conference in March when he spoke on Interoperability for Scholarly Annotation and the desire for a uniform, pervasive method for describing a variety of resources, in this case using the DOMEO annotation toolkit. At the same meeting Peter Brantley described the Hypothes.is open annotation tool for the collaborative evaluation of information which is also based on the draft standard.

More recently Todd Carpenter (Executive Director of NISO which itself has a project on annotation) provided an excellent report in The Scholarly Kitchen on the iAnnotate meeting which took place in San Francisco in April 2013. Significantly, while much of the recent discussion tends to focus on the STM fields, this meeting featured a number of examples of annotation from the social sciences and humanities such as MapHub and Pelagios.

Todd highlighted well the issues inherent in annotating digital items, particularly matching-problems and locating reference points which can be anchored in terms of time and location. In some ways telling of the need for solutions is the comments discussion which follows Todd’s piece which details the problems that exist and which are themselves examples of annotation. He points out that the very design of the comments on the blog mean that his response to a comment may be tied to that comment, but cannot be tied directly to other comments that he may also reference in his response and as annotations cannot be tied to what people might be saying on another service.

One point that remains to be decided in setting standards for open annotation is whether to develop new tools such as ReadCube (Nature Publishing Group) or Utopia Documents which allow you to read and annotate articles, allow publisher specific annotation tools to become standard features or should we be looking at other new publishing tools like Authorea which suggest alternative ways of making collaboration on scholarly articles simpler. Whatever the outcome, I agree with Todd that the scholarly publishing community, the users, need to focus more attention on annotation services that are being developed, many by researchers themselves.
