- In Science, assertion without evidence is merely hypothesis. This is also true for many other annotation venues. OA needs a clear way to signify whether it is hypothesis or evidence-based assertion that is claimed for the annotation body, and signify the supporting evidence.
- Actionable annotations need more thought. It may be that oa:Motivation is an adequate model, but for collaboration between producer and consumer we have found a need for more granularity about what is hoped for by the producer.
- The outcome of queries as the subject of annotation. Even for documents, it seems useful to be able to express things like "A regular expression search based on "...." yields seven sentences asserting that Admiral Perry reached 93 deg North. All of them are wrong."
