This is just one of many annotation system issues.

Annotation Types

Annotations can be used for different purposes (e.g. corrections, agreement, disagreement, voting, etc.) Should a fixed set or open ended set of annotation types developed?

Open Ended Set

An open ended set of annotation types has the characteristic that it can evolve over time. A disadvantage is that client browsers can not as easily select on the annotation type for highlighting or elimination purposes.

Fixed Set

A well chosen fixed set can potentially make the annotation system easier to use. The following sets have been proposed:

Untyped Response

An untyped response avoids the entire issue. This is used by HyperNews

Agree/Disagree

This strategy is used by WIT

Brian's B.'s proposal

Brian proposes:

Suggested Links
Direct Replies
Seals of Approval (SOAP)

Principia Cybernetica

Principia Cybernetica proposes:

Comment
Refutation
Confirmation
Correction
Illustration

What other ones have been missed?

The fairly obvious compromise is to provide for an open ended set of types, but specify a carefully chosen initial set.
