RE: [tigerstripe-dev] Annotations question.

[Yuri Strot <yuri@xxxxxxxxx>]

Hi Richard, John,

This behavior is a framework feature which was implemented to make TAF more stable. Annotation Framework store package definitions of the annotation content in the all annotation files. This make possible to load and edit annotations even they are defined in the plugins which was removed.

As Eric mentioned some times ago, different users can use different sets of annotation types. But if there are no package definitions for annotation content, annotation file will be unreadable for EMF and we will lose all annotations there (even through some of the stored annotations are valid).

Actually, there is not a problem to make such annotations read-only or invisible for user who haven't annotation type definitions. But in this case we can face the another challenge - if somebody remove unnecessary plugin with some annotation types, all annotations of these types will be lost while they are still storing in the workspace. And I think it's not so dangerous to make possible edit this annotations, because user can edit annotation file content anyway.

Yuri Strot
