Oct 13, 1999DOI3 Main activities of the last year Metadata framework –enables more sophisticated applications Applications using this framework Registration agencies needed basis of these to be worked out first (now done).

Oct 13, 1999DOI12 Why metadata with DOIs? a prerequisite of applications other than simple routing to one URL e.g. go to “appropriate” copy –local copy; choose alternative source e.g. “transact this item”; services about the item makes DOI an “actionable identifier” = identifier + resolution + supporting data access enables more complex applications than one URN

Oct 13, 1999DOI13 DOI metadata requirements “Resource description” (any “Creation”) and Rights description (transactions, services) Use existing systems (identifiers, data) –Do not reinvent the wheel No ambiguity (“well- formed”); automation

15 Metadata framework Generic for all types of content –convergence renders differentiation meaningless Focus is intellectual property management –but does not force one specific model of management Enabling, not replacing, other schemes –creating an interface Broad in scope –identification, description, transaction Based on tested “real world” models –CIS; IFLA

Practical way forward a powerful analysis tool –e.g. one work/several formats (relationships) practical results –e.g. EPICS (Editeur Product Information Communication Standard) (EDI, book trade etc) –XML/RDF expressions –common data dictionaries etc. indecs results at end of 1999 –but used as a basis by IDF since early 1999

Oct 13, 1999DOI19 DOI framework for applications Small set of “kernel” data for each DOI –Depending on intellectual property type –But interoperable (underlying data model) –Minimal data, probably common Define “genres” to describe each intellectual property type –e.g. journal article We need to publish improved explanations

Oct 13, 1999DOI20 Applications doi>

Applications (1) Seeking further applications - generic, interoperable Developing more sophisticated tools metadata framework multiple resolution possibilities DOI already in use : current implementation e.g. American Chemical Society: DOI as common identifier for a work,  page offers delivery options (formats etc)

Oct 13, 1999DOI22 Applications (2) Initial application prototypes –paving way in generic issues and applications –supporting data (metadata) structure Mix of development by IDF and encouraging others Aim: - application development outside IDF - IDF providing generic framework

23 Applications (3) Persistent linking –“DOI-X” project, 1999 (more on this later) Workflow implementation tools –RCP’s “Lynkbase” announced Rights management –“Frankfurt Virtual” announced; –DOI-R experiment being launched Others, e.g. –Document delivery (UK), Libronix Digital Library…etc

Oct 13, 1999DOI24 The “DOI-X” prototype Prototype a first application: ref-linking between documents In so doing, deal with: –metadata into workflow issues –metadata framework issues

Oct 13, 1999DOI25 The “DOI-X” prototype Prototype a first application: ref-linking between documents In so doing, deal with: –metadata into workflow issues –metadata framework issues Aim of this application: persistent linkage –STM publishing as an example, but wide potential application (any hyperlink)

29 DOI Design principles (1) Global, interoperable –applicable to any “Creation” Used by anyone (not only publisher) –actionable identifier Integrated with existing or developing standards - technical: W3C; IETF; ISO, NISO, etc - information architecture: INDECS, etc

Oct 13, 1999DOI30 DOI Design principles (2) “Federal”: users of the system make decisions at the lowest appropriate level

Oct 13, 1999DOI31 Example of “federal” principle: DOI / DOI numbering system /123

Oct 13, 1999DOI32 DOI Design principles (2) “Federal”: users of the system to make decisions at the lowest appropriate level - Information management architecture Prefix namespace, metadata schemes - Resolution technical infrastructure - Economic model Governance layer ensures interoperability

Oct 13, 1999DOI33 DOI implemented DOI adds value but incurs costs: Number registration –validation, maintenance, metadata, guidance Infrastructure –resolution service, scaling, development Governance –rules, further development

Oct 13, 1999DOI34 DOI implemented (2) DOI system to be self-financing Funded by registrants not end users – currently: $1000 one-off charge for prefix Aim to move to more flexible schemes – Federal model allows this per sector etc. – Registration agencies Investigation and plan

35 Registration agencies IDF to provide governance layer only –Ideally funded by federation of agencies IDF sets out minimum criteria for participation: –technical; information management; $ Does not prescribe details of individual businesses Comparable models we are examining: –ISBN; EAN/UPC; Visa; etc.

Oct 13, 1999DOI41 Three next steps Clearly articulated aims –how identifiers + metadata form a basis for commerce (actionable identifiers): vision Actions to implement this –DOI metadata registries –tools e.g. multiple resolution (Handle) –Registration agencies Finance activities to retain momentum

Oct 13, 1999DOI42 Identifiers and metadata as the basis for E-Commerce of copyright “Names Numbers and Networks” conference –Nov 15, Washington; –indecs/ Library of Congress/ US Copyright Office Proposed joint committee to take forward all work done so far (IDF participating) –Commerce and Legal Data dictionaries, etc. Implementations in 1999/2000

Oct 13, 1999DOI43 Registration agencies “Federal model” to be basis Publish draft minimal requirements for: –technical requirements –information management –infrastructure (governance) support Invite interested parties to work with us –members; PA’s via IPA; non-members –workshops and 1:1

Oct 13, 1999DOI44 Financing the future 33 member organisations supported us since launch; only a few not continuing No active recruitment since 1998 Now starting next round of support requests –better, faster, explanations, guidelines, etc –faster implementations
