Content of talk
  • I Why subject-specific services?
  • II Open Archive Distributed in Physics
  • III International embedding and organizatio

3
Part I Why subject-specific services?
  • Knowledge repository requirements
  • Restricted
  • Complete
  • Professional
  • Research-driven
  • Additional subsject-specific services

4
1. Why restrict knowledge basis?
  • Higher ratio of relevant information retrieved
  • Less missunderstanding different meanings and
    content for same word in different fields

Test 1
5
2. Why complete repository?
  • Prime research needs
  • instant (Web, no delay) information of all
    relevant new results
  • complete information fom anywhere in the world
  • One stop service despite a multitude of
    distributed heterogenous repositories.

Consequences for financing concepts
6
3. Why professional content repository
  • Researchers need mostly information from their
    professional colleagues.
  • Researchers can act only in their subject-field
    as referees, quality filters for the wider
    public, comment and select.
  • The Web allows for a multilevel professional
    quality management for all heterogenous purposes

7
4. Why research driven repository?
  • Authors have the highest motivation to be read,
    to get their documents distributed and archived.
  • Author communication communities are
    subject-specific.
  • Scientists understand only their
    subject-colleagues
  • Research is organized most often in
    subject-specific topical institutes

8
Part II Distributed Open Archive for Physics OAD
  • Vision of the ultimate subject-specific Open
    Archive
  • All departments worldwide as prime, complete,
    open free repositories
  • Secondary virtual add-on services use these
  • Quality filters
  • Collections
  • topical archives

9
Present incomplete realization
  • All worldwide departments
  • Few cooperate by local quality filters yet
  • Few comply with metadata (1000 of 40000
    documents)
  • Few give explicit open access (keep authors
    rights)

PhysNet
10
Completeness of data in a heterogenous world
  • Free locally posted documents PhysDoc
  • Free archived theses Depts, Univs., DDB,..
  • Free preprint repositories ArXiv
  • Free fulltext journals
  • Free research lab docs CERN, ANL, ..
  • University Publishers
  • Journals of Natl. Societies APS, IoPP
  • Commercial journals

13
Oai Cooperation of repositories
Oai lists
  • Data providers comply with Oai
  • Yes, if they are not service providers
    Departments
  • Yes, if they are free access providers
    ArXiv
  • Subtle, if national society publishers APS,
    IoPP
  • No, if commercial publishers Elsevier,..

scirus
Cut throat competition of service providers with
best service for same documents
Commercial publ. collect free access documents
14
Political and Funding Policy
  • Effective services for research
  • Money to libraries per No of accessible documents
  • Multiple access ways TibOrder vs others
  • Regulations for hiring scientists to Universities
  • Funding selforganization of research communities
  • University publishers as regular prime research
    outlet
  • Fund IuK research to professionalize content
    search

15
Subject-specific National Port of Entry
  • German Physical Society DPG plan
  • Cooperative project of partners FIZ, TIB, ISN
    KFP

Rescue boat syndrom?
16
International Networking
  • No bias policy no single society allowed to
    dominate
  • Funding policy each society finds ist own funds
  • Broker policy democratic network of brokers
    DFN-Project
  • Department cooperation
  • Operator
  • Quality filters select what to enter PhysNet
  • Metadata for documents
  • Home page for document lists
  • University publishers (vetting and archiving)
  • National entry points for Oai.

21
A dicussion in the train
  • Scientist
  • Did not know what services we were deprived of
  • Librarian
  • Assumed to know what services are good for
    science

The young Elsevier......
did ask the scientists What new services are
needed?
22
Principles for Document Services for the Sciences
  • Must be scalable 1 Bill. Docs in
    Physics/a
  • Distributed data bases author
    controlled
  • Free distribution exclusive authors
    right
  • Worldwide accepted Metadata standards DC
  • Free access to all research results ownership
  • Comply with needs of scientists
  • Competitive add-on services
  • To serve what customers want, not what they ask
    for.

23
PhysNet, a field specific service
www.eps.org/PhysNet
Headed by EPS
controlled by its Action Commmittee
on Publication and Scientific
Communication

24
The Concept of PhysNet
  • Crawl across all distributed Physics Departments
  • Same Metadata as Math-Net IMU,
    EPS
  • Distributed Gatherers locally
    allow/deny !!
  • Distributed Brokers no nation to
    dominate
  • Agreements for an unbiased distributed system
    Charter
  • Distributed manpower at present 1 Mill.
    /a
  • Serve all types of information


25
To cope with about
Departments worldwide Physicists
Harvest gatherer
  • 3000 distributed repositories
  • their local documents and document lists
  • numerous distrib. gatherers
  • numerous brokers
  • No central repository

28
A field specific professional service has to meet
the expectation of a quality serviceThe
service should not contain everything but only
material certified by physicists to be relevant
and good physics.
Thus we need certification levels. PhysNet has
but just one what is on Physics Departments
webservers
29
Scholarly Publishing, Vetting and Peer
Reviewing, Metadata, and Archivingin the past
age
Some e-prints free for the community!
A lot of work for the author!
DocumentMetadata
High prices for the library!
Exclusive rightsfor the publisher!
30
What refereeing do we need ?
  • Instant publishing
    before refereeing
  • Time stamp for prime research before
    refereeing
  • Archiving of relevant information
  • Competitive parallel) refereeing
  • Multilevel refereeing
  • Full information published to be fair to referees
  • Open refereeing signed Annotation instead of
    advice
  • Voluntary refereeing to be a pleasure for
    referees

31
The role of University Libraries
  • Be Oai-Database Provider of complete local
    Information
  • Assure free full text access of all research
    material
  • Assure correct metadata usage (by training or
    adding)
  • Do handshake with National Archives
  • Be Oai-Service Provider of complete local
    information
  • Vetting system with the local department
    scientists
  • Train users to pick from the multitude of
    Oai-service Prov.

Vetting and reviewing at German Universities
  • Cooperation of universities in North Germany
  • (Hamburg, Oldenburg, Bremen, Kiel, Rostock,
    Greifswald)
  • in evaluation of online teaching and research
  • in usage and production of multimedia
  • in e-publishing and establishing a joint
    university press for e-publications
  • pilot project of Hamburg Oldenburg
  • Local vetting with department scientists and
    library
  • peer reviewing between different universities
  • shared functions (work flow system, marketing
    ...)
  • separate functions (business model, financing
    ...)
  • Æ virtual university press of an open and growing
    number of online and peer-reviewed university
    presses

1. Discussion (workshops, meetings, ..)2.
Concept (free access, a multitude of data
providers and service providers but one
internationally to be accepted standard)3.
Software and workforce sharing.
The concept of the Open Archive Initiative OAi
  • Three layers

35
PhysNet, MareNet, PhysDis Math-Net comply right
from their beginning in 1995/6 the concept of the
Open Archive Initiative
36
A success story Dissertations Online in Germany
  • Workflow and Metadata from Author to Department,
    Library, National Archive
  • All fields, all Universities
  • One scheme for DC-Metadata
  • Local Archives, national providing
  • Formal rules for all.

  • I Why subject-specific services?
  • II Open Archive Distributed in Physics
  • III International embedding and organizatio

Part I Why subject-specific services?
  • Knowledge repository requirements
  • Restricted
  • Complete
  • Professional
  • Research-driven
  • Additional subsject-specific services

4
1. Why restrict knowledge basis?
  • Higher ratio of relevant information retrieved
  • Less missunderstanding different meanings and
    content for same word in different fields

Test 1

2. Why complete repository?
  • Prime research needs
  • instant (Web, no delay) information of all
    relevant new results
  • complete information fom anywhere in the world
  • One stop service despite a multitude of
    distributed heterogenous repositories.

Consequences for financing concepts

3. Why professional content repository
  • Researchers need mostly information from their
    professional colleagues.
  • Researchers can act only in their subject-field
    as referees, quality filters for the wider
    public, comment and select.
  • The Web allows for a multilevel professional
    quality management for all heterogenous purposes

7
4. Why research driven repository?
  • Authors have the highest motivation to be read,
    to get their documents distributed and archived.
  • Author communication communities are
    subject-specific.
  • Scientists understand only their
    subject-colleagues
  • Research is organized most often in
    subject-specific topical institutes

Part II Distributed Open Archive for Physics OAD
  • Vision of the ultimate subject-specific Open
    Archive
  • All departments worldwide as prime, complete,
    open free repositories

Implementing OAI at German Universities
  • DINI (http//www.dini.org)
  • German Initiative for Networked Information
  • carries out guidance for implementations all over
    Germany
  • develop a strategy to cover German universities
    (libraries with document servers)
  • Aim
  • Serving a distributed archive network
  • Setting up a contact point for OAI in Germany

Collections to be Represented in Oai-PhysDoc
  • PhysDoc
  • Distributed document Database for Physics
    worldwide
  • using HARVEST as Retrieval mechanism
  • University document servers
  • North German Univ. superstructure
  • DissOnline.org Physics part
  • Physics part of NDLTD
  • Arxiv, MIT, .. Physics part

OAI Implementation
  • modified HARVEST holds SOIF and DC metadata in
    local text files
  • storage size no problem
  • decision to convert data offline and store
    structured data in SQL database (mysql)
  • use DC when possible, otherwise map SOIF to DC

OAI Implementation
  • software written in PHP
  • protocol
  • easy because it uses modified implementation of
    HU Berlin
  • metadata converter
  • maps SOIF to DC
  • converts different DC representations to one
    common one

49
Future work
  • improve metadata converter
  • improve summarizers
  • closer look at different DC representations
  • tell people to use metadata
  • OAI workshops
  • ease production of metadata

DC-Standards and Sets of OAi
  • German National Library
  • DC7
  • TheO-Duisburg
  • OCLC-NDLDT
  • Math-Net Worldwide Int.Math.Union

National activities to support the OAi
  • DINI German Initiative for Networked Information
  • similar to CNI
  • Cooperation between
  • Research Libraries (DBV),
  • Computer Centres (ZKI),
  • Media Centres (AMH),
  • Initiative of Learned Societies IuK
  • DINIs Appeal to join the OAi (2000)
  • Training camps for German Oai-Data Providers

54
Next steps I
  • German National Library DDB set write MMM and
    import (all fields)
  • VT ETD-Metadata write MMM and import
  • Use set for import/export VT-ISN

Good for increasing No of documents Increase
acceptance Prove VT-ISN
55
Next steps II
  • Benefit from Research for added Intelligence at
    VT for MARIAN broker
  • Branching queries to VT and import answers
  • Install modules
  • Go towards one joint broker

56
Thanks for the invitation
  • Virginia Tech group of E. Fox leading in
    development of online digital library concepts
    for any learned field and language
  • ISN complements in developing online services for
    a specific field (Physics) and just one single
    language (broken englisch).

57
Next steps III
  • MARIAN Bypasses for ISN-PhysDoc
  • Intelligence for the Oai-Dataprovider
  • Intelligence for the Oai-Serviceprovider

VT-ISN steps IV
  • Joint Representation of DFG-NSF project
  • One Server, one address, one project, one crew ..

60
Next steps V
  • Share User statistics and Evaluation

What do Physicists want? (In a new
surrounding) Experiments and Evaluation Instead
of questionaires
61
  • Acceptance of a service comes by
  • Bottom up just do it and spread the rumour
  • Top down Charter of IMU, EPS
  • To register Institutions, Departments, Graduate
    Schools, Universities
  • 4. Joint international standards and cooperation
  • 5. Work sharing (infinite workforce)
  • 6. Professionalism
  • let the scientists provide content
  • Let the libraries, computer centers provide
    service
  • Let the Administration levels find a way to
    assure quality selection to the worldwide
    services.
