4. Web Annotation Web Annotation can be used by scholars or web-users to share information about certain resources or topics. Existing Annotation systems: Need Client side script to create and view the annotations. The Annotea LEMO
5. Time Time of the annotation: Resources may: Move [location] Change [updated] Disappear
6. Annotation Open and Independent The focus on sharing annotations. Persistent Readable at anytime. Archived [Targets and Annotation body]
7. Resources Archiving What if the Resource doesn’t have a memento?! We will not be able to view the annotation when the original resource move. Push all related resources to the Archive . In this case, we make sure that, all resources are archived and persistent.
12. Open and Independent The annotation should be retrieved by the browser without the help of any extra plugin or adds-on. SVG [Scalable Vector Graphs] used to represent the annotations. SVG is a Text-based Markup language written in XML Supported in [Firefox, IE9, Chrome ,Safari]
13. Scalable Vector Graphs [SVG]: Searchable: Google started indexing the SVG content on August 31st, 2010. SVG file can contain Audio, Video, and image tags. Image tag is supported by all browsers Audio and video tags are supported by SVG readers but not browsers yet. Promises that they will be supported in future updates. SVG video tags can be rendered to flash in the server side in order to overcome the lack of support. Supports Scripting (JavaScript).
24. User annotations [text, drawings, etc..]The server sends all the related resources to the [Archiving service ] . It creates separate memento for every resource. URI-A, URI-T, URI-C URI-M1, URI-M2, URI,M2

35. Conclusion Web Archives helped in solving the issue of keeping the annotation persistent over time, and the use of the SVG technology helped in keeping the annotation readable in any browser without any need to install extra plugins.
