- 2. Outline • Overview and history • Demonstration • Use of METS • Technological overview • Future development and release plans
- 3. Overview: What is METS Navigator? METS Navigator is a METS-based system for displaying and navigating sets of page images or other multi-image digital objects.
- 4. Previous page-turning implementations at IU • DLXS Text Class – For text collections – Since 2000 (Wright American Fiction) – Integrates TEI-encoded texts with page images • Custom-built – For IU Sheet Music project – Relies on images present in a certain structure on the file system • Neither option extensible enough for future collections
- 5. Why a new page-turner? • METS Navigator was built initially to provide access to brittle books digitized by Indiana University Libraries’ Preservation Lab • Recognizing the need for such a tool page-turning tool across digital library projects, METS Navigator was built to be extendible and configurable.
- 6. Demo • Default Collection (sample brittle books) • Jane Johnson Collection • Chymistry of Isaac Newton
- 7. Metadata needs in interface
- 8. Why choose METS? • Can wrap the structural, descriptive, and administrative metadata necessary for the interface together in one place • Flexibility in choice of descriptive metadata schema • Format neutral • Frequently used for SIPs
- 9. Purposes of our METS documents • Now: Provide metadata needed by page turner • Later: Long term management of digital library objects in a repository
- 10. METS sections for page turning • • • • <fileSec><fileGrp USE="screen"> <fileSec><fileGrp USE="full"> <structMap TYPE="physical"> <structMap TYPE="logical">
- 11. METS <div TYPE=""> • Now – Show/hide nodes in a structure – Flag illustrations within a book – Mark blank pages • Future – Indicate a group of objects to be displayed together – Specify the scope of navigation – Indicate where to find an ID for linking into another application – Provide scope for searching?
- 12. Next steps: Metadata for digital object management • <metsHdr> • <fileSec><fileGrp USE="archive"> • <dmdSec> • Others – – – – techMD rightsMD sourceMD digiprovMD
- 13. Technological Overview • Programming Language: Java ( http://java.sun.com/) • Web Application Framework: Struts ( http://struts.apache.org/) • Java & XML Data Binding: Castor ( http://www.castor.org/) • Build & Deployment Platforms: Ant ( http://ant.apache.org/) & Tomcat ( http://jakarta.apache.org/tomcat/)
- 16. Release and Distribution Plans • METS Navigator will be released as an open source project under an IU "BSDlike" license and available from SourceForge • Distribution will include small, sample collection and multiple display configurations • Distribution will include both .war Web application and .jar library • Anticipated release date: May 31, 2005
- 17. Future plans • User testing – For end-users – For implementers • More flexible display of descriptive metadata • Increased configurability of layouts • Development of "METS Builder" tools • Based on user feedback and emerging best practices, continue to revise METS requirements and expectations

Editor's Notes
- #18: descriptive metadata currently a @label in the top level <div> of structMap. Want to make more flexible to pull from dmdSec and can change depending on what item one is viewing.
