Persistent Annotations Deserve New URIs
- 1. Persistent Annotations DeserveNew URIsAbdulla Alasaadiaalasaad@cs.odu.eduMichael L. Nelsonmln@cs.odu.eduOld Dominion UniversityJCDL 2011Ottawa, CanadaJune 15, 2011This work supported in part by NSF IIS-1009392.1
- 2. IntroductionAn annotation canbe described as a relation between different resources with different media types like text, image, audio, or video.2http://2.bp.blogspot.com/_2ASHdLrOGi0/TNmzuwr3kKI/AAAAAAAAAzI/Y91p52Huq3s/s1600/elephant-tusks-460_1016757c-739042.jpghttp://bioweb.uwlax.edu/bio203/s2007/shahrach/map.JPG
- 3. GoalsA unique URIfor every annotation.Persistent annotations and resources.Annotate specific part of media. Keep track of the resources. Present annotation in browser.Meet the OAC model requirements.3
- 4. OAC Model4oac: Annotationrdf:type ex:Annooac:hasTargetoac:hasBody ex:Africaex:TuskOACintroduces a new resource that creates the relationship between the body and target.

- 9. Suppose wewant to identify a non-rectangular region?Media fragment specification does not support non-rectangular shapes.SVG technology allows users to select particular parts of the images of any shape.

- 11. The annotating serviceshorten the Long URIs using Bit.ly API.
- 12. Easier to share,and collect statistics.

- 25. Resource maps andlink headersResource maps describe the aggregation of all these URIs.Resource maps can be discovered by examining the http link response headers when dereferencing any of the URIs.11

Editor's Notes
- #16 SVG used Easy to create an annotation with different resources, XML -> RDF Supported by ALL major Browsers.Indexable, we can find the annotation or part of the annotation in the search results of the search engines.Amny resources ! -> Resource Maps.
