Persistent Annotations Deserve New URIs

1. Persistent Annotations Deserve New URIs Abdulla Alasaadi aalasaad@cs.odu.edu Michael L. Nelson mln@cs.odu.edu Old Dominion University JCDL 2011 Ottawa, Canada June 15, 2011 This work supported in part by NSF IIS-1009392. 1

2. Introduction An annotation can be described as a relation between different resources with different media types like text, image, audio, or video. 2 http://2.bp.blogspot.com/_2ASHdLrOGi0/TNmzuwr3kKI/AAAAAAAAAzI/Y91p52Huq3s/s1600/elephant-tusks-460_1016757c-739042.jpg http://bioweb.uwlax.edu/bio203/s2007/shahrach/map.JPG

3. Goals A unique URI for 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 Model 4 oac: Annotation rdf:type ex:Anno oac:hasTarget oac:hasBody ex:Africa ex:Tusk OAC introduces a new resource that creates the relationship between the body and target.

5. Annotation Example 5 http://bit.ly/g55gvD http://bioweb.uwlax.edu/bio203/s2007/shahrach/map.JPG

7. Describes the annotation.6

9. Suppose we want 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 service shorten the Long URIs using Bit.ly API.

12. Easier to share, and collect statistics.

25. Resource maps and link headers Resource 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

26. 12 (A) The annotation Ex:Anno oac:hasTarget oac:hasBody uu1 ex:Tusk oac:constrainedBy oac:constrains ex:svg ex:AFRICA

27. 13 (B) Adding mementos Ex:Anno memento M-1 oac:hasTarget oac:hasBody uu1 ex:Tusk memento oac:constrainedBy oac:constrains M-2 ex:svg ex:AFRICA memento M-3 memento M-4

28. 14 (C) Resource Map to aggregate resources ReM Ex:Anno ore:describes memento M-1 Agg oac:hasTarget oac:hasBody uu1 ore:aggregates ex:Tusk memento oac:constrainedBy oac:constrains M-2 ex:svg ex:AFRICA memento M-3 memento M-4

29. Implementation Two main services: Create and share the annotation. Retrieve and represent the annotation. Scalable Vector Graphs SVG. ORE Resource Maps. WebCite. Bitly. 15

30. SVG_Edit Plugin 16 http://code.google.com/p/svg-edit/

31. Create The Annotation Our online annotating service Push to Archive Generate RDF Annotation’s data Browser Generate ReM Annotation’s URI Shorten the URI http://bit.ly/i2AfwN 17

32. Retrieve and share the annotation http://bit.ly/i2AfwN 18

34. Annotating the media fragments was made possible using the SVG and its media tags.

35. Using the web archives solved the issue of keeping the annotation persistent over time.

36. The Resource Map is the perfect solution to keep track of all the resources.
