Extensions for Data Annotation

Source: FilteredPush extensions to OA for data annotation

  • Evidence (objects that support the assertions of the oa:Body)
  • Expectation (objects that convey annotator's broad expectation of changes to be made to the oa:Target ).
  • QuerySelector (superclass of selectors at the record and sub-record level below that for which an identified dataset has a URI)

These and associated predicates are presently described in documents here. At this writing they may be in transition.
