4

5

Agenda

• DOI update /overview Norman • Metadata issues: designing DOI genres

- coffee break -• Resolution issues Larry

- lunch -• Whats needed (all)• How to proceed• Prototypes and practical next steps

7

Review of progress

• Consistency: no major “U turns”

• Progress: design and implementation

• Engagement: wider and deeper– metadata discussions – identifier issues

• “Development” and “Product”– “The road ahead” analogy

Review

• Components of the DOI

10

• A number (or “name”)– assign a number to something– (compare: telephone number)

11

• A number (or “name”)– assign a number to something– (compare: telephone number)

• A description– say what the number is assigned to– (compare: directory entry)

12

• A number (or “name”)– assign a number to something– (compare: telephone number)

• A description– say what the number is assigned to– (compare: directory entry)

• An action – make the number able to do something – (compare: the telephone system)

13

• A number (or “name”)– assign a number to something– (compare: telephone number)

• A description– say what the number is assigned to– (compare: directory entry)

• An action – make the number able to do something – (compare: the telephone system)

• Policies– how to get a phone number; billing– (compare: social /business structures)

Any form of identifier

ENUMERATION

DESCRIPTION

<indecs> framework allows a DOI to describe any formof intellectual property, at any level of granularity

RESOLUTION

Handle System allows a DOI to resolve to any and multiple piecesof current data

Progress

• An extensible infrastructure, architecture– a firm basis for building consistent, reliable,

systems

• More members, more prefixes, more DOIs

20

Progress

• a major implementation

• other implementations near

• more signs of influence: – W3C; ISTC; E-Books

• clear vision: “conceptual integrity” (Brookes)

21

Potential pitfalls

• STM - identified with text and with STM esp?

• Rigorous approach - “theoretical”?

• Technical - not understandable?

• Anglo-American - not international? • Key individuals - in depth support?

• Open development - not yet ready?

• Unifying - fragmentation?

22

A note on time frame

• “If this stuff wasn’t difficult we wouldn’t be doing it”• The first actionable identifier (all the components) • Oct 1997 concept launched (simple form)• March 1998 IDF launched; two years of work• Some comparisons:

– URN: 1991 - ; DC: 1994- ; FRBR: 1992-98;

– W3C: 1994-; IMS: 1996-; RosettaNet 1998-

23

Applications

• Crossref (PILA)– “Crossref is the first practical demonstration of why

the DOI is important, and how it can be used to improve Web publishing. Though it was implemented by journal publishers…the concept could be applied to other genres…” (Seybold Report, 14 June)

– see IDF “E-Citations” paper *

• Images– BioImage; and extension?

24

Applications

• E-Books - working with: ONIX/EPICS; OEB; EBX and AAP E-

Books standards activity (David Martin)

- community is diffuse and hence applications as yet undefined: eBooks (ISBN?); components; links?

• Instructional materials (NICEM)

• Music industry • Others? E-News; Legal; Patents; “Grey literature”

Applications will drive deployment

25

Applications and metadata• approach vindicated

– See recent papers by Carl Lagoze; Priscilla Caplan

• practical implementation of <indecs> through ONIX/EPICS dictionary– extension/collaboration with other areas e.g.music/video; SMPTE;

MerchEnt; etc

• documentation in detail: – Handbook (section 5, and appendices 2&5)

– More detailed “template” for genres coming shortly

• mechanism for metadata (e.g. metadata@DOI 123…)– XML declarations; schemas

26

Commercial implementation: “deployment”

• Technology is (relatively) easy

• Basis for Deployment outlined (end of 1999)

• Initial financial model (June): simple

• First and second “wave” of interested parties

• Terms document

• Applications will drive deployment (genres etc)

27

Extensibility: metadata framework

• more on this in next session • rights transactions• see latest indecs framework document

• role of XrML to be investigated

• “DOI-R” • proposed by analogy to DOI-X

• scope problems

• now looking at more defined prototype with FBF

• Rights is not “just another application”

28

Extensibility: Digital Object Architecure

• Digital Object Architecture includes Handle, repositories, etc.– see papers by Kahn et al *

• multiple resolution• workflow tools• repository:

– “stated operations” = DOI services?

– genre definitions, schema, etc?

• public key infrastructure

29

Documentation

• Review 1999: – DOI Current Status and Outlook May 1999

• Review 2000• Handbook (DOI 10.1000/182) • Papers

– “DOI: implementing a standard ….”

– “one to many”

– etc

30

Marketing

• “W3C approach” up to now: – don’t promise what can’t deliver; show by example

• CD-ROM marks start of next wave– outreach and applications

31

Some other key activities (1)

• Handle:– New release of second major version– Handle infrastructure improved – CNRI plans for Handle – Browser support: Mozilla?

• Metadata, rights:– ONIX/EPICS etc implementing indecs – XrML

• W3C:– URI Activity – “intellectual property on the web” workshop

32

Some other key activities (2)

• Other intellectual property activities: – e.g. MPEG-21 as possible focus for cIDF,

SMPTE, etc.• Legacy identifiers (ISBN, ISSN, etc)

– common issues for identifiers• Work with new identifiers (e.g. ISTC; E-books)• Major issue: mindshare support for standards

– avoid fragmentation

33

Your involvement

• Workshops• Prototypes• New working groups (E mail lists) proposed:

– Handle/resolution

– Identifiers/metadata

– Information interchange

34

The future • genres: articulation and development (Hdbk, Appx 2)

– metadata declarations• multiple resolution: services

– Service@DOI:10.1000/182– e.g. Rights@DOI:10.1000/182 (YBP, 1998)– e.g Metadata@…..

• rights • outreach• identifier/ metadata/ standards/ i.p. community

35

Multiple resolution: services

• To be investigated:• Metadata pointer for all DOIs (kernel)• XML schema for genre metadata• List of other desired services and policies• Registry of “data types” = service (and tools)• Registry of genres• Tools to make all this easier

36

Review of progress

• Consistency: no major “U turns”

• Progress: development and implementation

• Conceptual integrity

• Practical results; and development

• More to be done on advocacy

• More to be done on applications, developments - this workshop
