  3. Remaining Issues • Definitions of • Anchors, regions (segmentation)** • Layers • Media • Need to verify that these are adequate for all media, including speech, image, etc. Would appreciate suggestions for wording concerning application to media

  4. Remaining Issues • Resource Header • Definitions of various entities • Consistency of attribute names etc. • Consistency of reference from annotation documents etc.

  5. Remaining Issues • Replace <tagUsage> in annotation document header with means to provide annotation categories used (and number of times used) Possibilities: • List of the categories (or ISOCat references) and frequencies • need to define an element for this • External document with the information • XML? • Specification of the categories without frequencies, e.g. documentation of the scheme • ???

  6. Remaining Issues • Rewording of feature structure specification to reflect change in fs spec that accommodates GrAF format for <f> • <f name=“FE” value=“perceiver”/>
