Web annotation
A Web annotation is an annotation associated with a Web resource (tipically an HTML page).By using a Web annotation system an user can "virtually" add, modify or remove information from a Web resource without actually modifying the resource.
The annotations can be though of as being applied on a trasparent layer on top of the existing resource. The annotation layer is visible only to users that share the same annotation system.
Annotations can be used, for example:
- to rate a Web resource (by its usefulness, user-friendliness, suitability for minors viewing)
- to improve its contents by adding/removing material
- as a collaborative tool: e.g. to discuss the contents of a certain resource
- as an artistic or social criticism medium by allowing Web users to reinterpret, enrich or protest against institution or ideas that appear on the Web
