Handle - Technical Update Larry Lannom CNRI Sept 20, 2002 Corporation For National Research Initiatives
Technical Developments: 2001/02 Maturation u Increase u in numbers - 5 M+ DOIs – New backend db – New admin facilities Increased scope of application areas – Learning objects – Images u Increased scope of research interest – – Identity management Grid - handles for events Laws & Regs (DTIC/TSO) Network storage Corporation For National Research Initiatives
Technical Developments: 2001/02 Maturation u Admin Tools – – u GUI installer, server splitter SQL backend Servlets for web based admin Administration Manual Development Tools – Python library (not yet licensed) – New hdllib example programs (net. handle. apps. simple) u Responding to dot com jitters – Exodus bankruptcy - added additional GHS, DOI LHS and proxy at CNRI u u u Support for encrypted communication between clients and servers Support for Java 1. 4 Lots more…. Corporation For National Research Initiatives
Other Efforts u Open. URL – ‘Fat URL’ coming out of Library community – Used to solve the Appropriate Copy problem – Being proposed as a general interface to DOI world u Interparty – Interop across rights clearinghouses, library authority files, etc u Internet Digital Rights Management (IDRM) Group Corporation For National Research Initiatives
Technical Developments: DOI Evolving Functionality u Parameter passing – Carrying information in the http: //dx. doi. org URL – Crossref prototype – Open. URL u Debate on data models and service architecture – Great potential flexibility t t Given an ID, what can you get How do you understand what you get – Moving targets t t u Web services, semantic web, Grid computing XML DTD, XML Schema, RELAX NG Adobe focus – Move forward with prototype, get RA buy-in Corporation For National Research Initiatives
DOI as Enabling Framework for Managing Content u Simple Goal: Build a framework for coherent management of content in an evolving digital realm – Make sure your intended audience can find it – Associate related information and services both now and later – Maintain integrity of original content u Complicated World: Years and even centuries of practice disrupted by technology – Content no longer physically fixed, but in motion and highly mutable – Digital entities have value, in the creation, but can be duplicated and disseminated at no cost – Digital convergence pushing content out of its familiar boundaries – Technology is accelerating u Persistent, manageable, and actionable identifier is a foundation of the needed framework – Basic mechanisms in place: id assignment, management, resolution plus associated metadata creation framework – Need common data models and architectures for extended use of what we have Corporation For National Research Initiatives
Acrobat Plug-in Project as Focus u Use DOI embedded in PDF to extend functionality – Show DOI as useful for item in hand as well as for links – Provide user with new functions/services as they evolve u Handle plug-in made aware of special DOI facilities u Resolve handle/DOI upon rendering u New functions/services driven by resolution result u User interface through customization of tool bar, menu items, dialog boxes Corporation For National Research Initiatives

What Have We Done u u u Put the DOI data in functional units in the handle record and the knowledge of what to do with them in the client Demonstrated with an end-user client (Acrobat) but equally applicable to middleware No constraints on adding additional functional units to a given DOI – Added flexibility and simplicity – Reduced ability to verify integrity across functional units u No attempts at on-the-fly bootstrapping for introducing new functionality to existing clients – Will require an updating process for clients Corporation For National Research Initiatives
A Namespace for DOI Functions 0. TYPE/doi. kmd TYPE *DESCRIPTION* 1 url http: //dx. doi. org/10. 1000/182 2 mime text/plain |
A Note on XMP u XMP access hooks in Acrobat but not Reader – Considered too much bloat for Reader – Presumably could change over time u Two choices – Put the DOI someplace else -- PDF metadata – Create our own hooks u We’ve tried both – Demos based on Acrobat – Also developed a version that reads non-XMP metadata Corporation For National Research Initiatives
What Next u Bring together the RA tech reps to roll out significant prototype – Need experience with additional data, real users – Decision on XMP – Go beyond PDF u Package it up and roll it out – License – Management of new functions: some sort of vetting process Corporation For National Research Initiatives
