  1. 1. Annotating digital texts in the Brown University Library<br />Andrew Ashton<br />Brown University Library<br />
  2. 2. Textual scholarship at Brown<br />Brown University Women Writers Project<br />Virtual Humanities Lab<br />Center of Digital Epigraphy<br />Modernist Journals Project<br />Hypertext, CAVE Writing, etc.<br />
  3. 3. The Pico Project<br />
  4. 4. Giovanni Pico dellaMirandola’s900 Theses (1486)<br />
  5. 5. AtomPub<br />AtomPub is an engine for creating, publishing, and updating annotations via HTTP.<br />XML-based format for sending, receiving data on the web.<br />Includes annotation body, metadata, links to target resource.<br />RDF to express relationships between collections, digital objects, and annotations.<br />
  6. 6. A place to gather, index, store, preserve, and make available digital assets produced via the scholarly, instructional, research, and administrative activities at Brown.<br />
  7. 7. Based on Fedora Commons<br />Rights management via Shibboleth<br />APIs and web services for campus developers<br />User interface to upload, catalog, and arrange personal materials stored in the BDR<br />
  8. 8. Annotation services<br />A<br />B<br />C<br />Annotation <br />Annotation <br />Annotation <br />Annotation <br />Primary<br />Object <br />Repository<br />Annotation <br />Annotation <br />Annotation <br />Annotation <br />My group’s annotations<br />My annotations<br />About component “C”<br />
  9. 9. Annotation services<br />Annotations are syndicated as Atom feeds, similar to those created from blogs. Scholars can subscribe to feeds based on their research interests and participation in collaborative groups.<br />The repository ingests the annotation as a new object, complete with its own metadata. RDF defines it as an annotation of another object.<br />Atom + XML<br />A scholar annotates a digital object. The annotation is packaged in an AtomPub document and sent to the digital repository via HTTP.<br />Syndication/Collaboration<br />Aggregation/publication<br />RDF/Linked Data<br />Groups of annotations (e.g., translations, editorial comments) are aggregated into new standalone documents and published with attribution. <br />Annotations are published as a Linked Data source using RDF, complete with ontological classification and links to the digital objects that they address. <br />All permutations of annotations, digital objects, and their derivatives are addressable as stable entities via a HTTP URI. Additionally, they are all subject to annotation, thereby blurring the traditional distinction between “primary objects” and “annotations.”<br />
  10. 10. Targeting portions of documents<br />TEI offers structural anchors (<p>, <div>, etc.)<br />XPointer offers one mechanism for addressing structural anchors via Xpath:<br />Example: http://www.brown.edu/texts/Bradstreet.xml#xpointer(‘/TEI/teiHeader’)<br />XPointer is insufficient as a sole solution for addressing fragments of TEI texts.<br />
  11. 11. Constraints<br />OAC convention for addressing parts of an annotation target.<br />Provides a model for addressing fragments of documents not readily addressed via a URI fragment identifier:<br />
  12. 12. RDF “Aspect slicing”<br />Creating RDF out of fragments of TEI (and other objects).<br />Addressable, URIs including semantic information and links back to source documents.<br />Enables annotation of semantic data within and across documents, rather than simply fragments or passages.<br />
  13. 13. TEI semantic data as a web resources<br />TEI<br />RDF<br />
  14. 14. RDF Constraints with TEI<br />Note about a person<br />oac:<br />Constrained <br />Target<br />Video<br />FOAF<br />Content<br />sameAs<br />Database<br />TEI<br />oac:<br />Constraint<br />oac:<br />Constrained By<br />
