  1. Annotationsfor the ALA Ron Chernich Principal Research Fellow University of Queensland, Australia

  2. TDWG ‘08 • Goals of the UQ eResearch Lab for DIAS-B in 2008-9 • Quick introduction to web based annotation services, capabilities, and technologies • Highlight choices, challenges, and implications • Provide sources for additional information

  3. DIAS-B Annotation Goals: Year 1 • Investigate existing collaborative annotation systems and select the most appropriate solution. • Investigate requirements for annotation services in other NCRIS capabilities and in ANDS • Investigate how to integrate it with the Metadata Repository and other components in the ALA system.

  4. What is an “annotation”? • Additional information attached to an existing resource (which may itself be an Annotation!) • Simple Example: • an email chain • A bookmark • Less Simple Example: • A highlighted selection on a web page with a comment • A structured correction to a data set • Complex Example: • An identified region of a multi-media resource • A specific view and zoom of a protein model

  5. Delicious Bookmarks

  6. Delicious annotation tool

  7. Annozilla Side-Bar

  8. Vannotea

  9. W3C Annotea • An extensible standard, part of the W3C Semantic Web initiative, defines a protocol for creating, updating, and retrieving annotations using an RDF XML schema having 7 properties: • Annotates (resource) • Author • Body • Context • Created/Modified (date) • Related

  10. Annotea Annotation Subclasses • Annotation is intended to be subclassed: • Advice • Change • Comment • Example • Explanation • Question • SeeAlso

  11. Simple Architecture Systems Annotea Web Service HTTP/XML OAI-PMH Web Service Web HTTP/HTML Users RDF Store Black Box with well-known public API’s

  12. If it weren't for the Clients! • What browser and version on what platform? • Firewall? • Browser Plug-in compatibility? • Website Widgits? • Proxy? • Portable Javascript! • Uncooperative Data Providers! • Intransigent sysadmins and their precious SOE!!

  13. Client Technology Cost of Ownership + “weight” of client Custom Browser (Amaya) Browser Plug-in (Annozilla) Ajax script (Marginalia) Proxy (Annotator) Form based (AnnoChump) Browser link (Delicious) Richness of User Interface

  14. What About Mutability? • Loose coupling of annotation and annotated resource can result in temporal degradation. • If mutability is permitted, do you harvest the annotation body, or the reference to the body? • A chain of immutable annotations provides an audit trail, but lengthy, out of date sequences may be perceived as just noise.

  15. UQ eResearch Lab Papers and Demos • Collaborative Annotation of 3D Crystallographic Models • A Synchronous Annotation System for Secure Collaborations • Annotating Relationships between Mixed-Media digital objects by extending Annotea • Implementing a Secure Annotation Service • HarvANA – Harvesting Community Tags to Enrich Collection Metadata • Collaborative, Semantic Tagging and Annotation Systems • Implementing a Secure Annotation Service • Open Repositories 2.0: Harvesting Community Annotations to Enhance Discovery Services • VIRGIL: Yet Another Approach for Archiving and Playback of Access Grid Sessions • Vannotea: A Collaborative Video Indexing Annotation and Discovery System for Broadband Networks • A Synchronous Multimedia Annotation System for Secure Collaborations http://itee.uq.edu.au/~eresearch
