Introduction to the Cooperation between CAS and
Jianxia Ma Xiaolin Zhang Zhongming
  • National Science Library,CAS

DRIVER Confederation Summit Ghent/Belgium 20th.
Oct, 2009
  • Background
  • What is CAS
  • NSL and some of its responsibility
  • NSLs international cooperation
  • CAS IR Grid Current Status and Future
  • Consideration of OAI metadata harvester system
  • Why DNET
  • Requirements
  • Testing
  • Future expectations

Background What is CAS
  • Founded on Nov. 1, 1949
  • Highest academic institution in natural sciences
    in China
  • Most comprehensive RD center in natural sciences
    and high-tech development
  • Highest national advisory body in S T

NSL and some of its responsibility
  • NSLLibrary system of CAS
  • As Knowledge Organizer and Curator of CAS, we
    have the responsibility to organize, coordinate
    and support institutes and researchers to create,
    organize, preserve and communicate their
    knowledge outputs, and to organize and to make
    use of these information as components of CASs
    knowledge assets.
  • As knowledge Officer of CAS, we have obligation
    to provide necessary technical platform, running
    mechanism and policy instruction for institutes
    and scientists, in order to promote open access
    of science and technology information.

NSLs international cooperation
  • As a part of NSLs twelfth fifth-year strategic
    plan, we are developing operational international
    cooperation. This is not only included academic
    exchange but also included substantial
    cooperation in resource development and service.
  • For example, DRIVER, COAR
  • Safe Places Network (National Library of the
    Netherlands KB )
  • LOCKSS (Stanford Univ.)
  • Our aim is integration into the world, developing
    internationalized capacity of service.

CAS IR Grid Current Status
  • In 2007, the CAS Institutional Repository Grid
    was brought forth
  • Each institute establishes its own local
    repositories as a node of the Grid
  • NSL constructs a centralized metadata repository,
    which could harvest the metadata of academic
    resources stored in many distributed
    institutional repositories
  • NSL also keeps an integrated search interface for
    the resources and provides other enriched services

Targets of CAS IR Grid
  • providing the organizational and technological
    framework for a CAS-wide IR infrastructure for
  • helping every institutes set up their own IRs to
    increase the visibility, and preserve their
    research outputs
  • implementing a harvester-based cross-repository
    search and browse service to enhance exposure of
    the CASs research output as a whole
  • making the GRID ready for becoming building
    blocks for national or international wide
    repository infrastructure

Distribution of Institutes of CAS
Future Institutional Repository Landscape CAS
  • 12 branches
  • 97 institutes
  • 9 supporting institutions
  • 1 Grad school 1 University

We have two steps to build our IR Grid
  • Step One Building Institutional Repositories in
  • Step Two Building the Federated Repository for
    the whole Academy

Step One Building Institutional
Repositories in Institutes
  • Four tasks we have done
  • Select the institute and set up examples for
    other institutes to follow
  • Develop IR based on DSpace
  • Integrate with the existing system (such as ARP)
  • Help the institute plan and implement IR
  • There are 39 Institutes signed the agreement and
    29 Institutes have deployed IR, Some Institutes
    have already have data.

Step Two Building the Federated Repository for
the whole Academy
  • Three tasks need to be done
  • Deploy the IRs and Spread the IRs to institutes
    across the country
  • Develop OAI metadata harvester system to harvest
    metadata from IRs in institutes to NSL center
  • Develop value-added and augmented services

Some consideration of OAI metadata harvester
  • OCLC open source software OAI Harvester 2.0 are
    selected to be extended and integrated into
    DSpace via a way of plugin
  • DRIVERs open-source D-Net toolset are also
    considered whether it will be a better option for

  • Open source
  • Open infrastructure
  • 2 years experience deployed in DRIVER
  • Cooperation between CAS and DRIVER

  • Stable, robust and flexible function
  • Localization/internationalization
  • Built-in mechanism for supporting
    localization/internationalization easily
    (interface, indexing and searching)
  • Support harvesting of a target repository which
    exposes its metadata with a customized metadata

  • have a plug-in or add-on based design of
    supporting extended development
  • we may want to provide services as generating
    knowledge directories or maps at different
    granularity level, co-operation networks of
    institutions or individuals, and other
    significant semantic enhanced services
  • Detailed updated handbook about technical
    architecture and structure

  • 1.DNET Foreground
  • 1)Driver Search interface
  • http//
  • 2)Validator Web Interface
  • http//
  • 2.DNET Background
  • 1)Repository Manager Interface
  • 2)Aggregator Manager Interface
  • http//
  • 3.We are looking forward to the stable edition

Future expectations
  • Investigation of DNET
  • As a member of COAR, we hope to get techniques,
    tools, resources and training support.
  • The fees of COAR should take into consideration
    of the capacity of every member
  • NSL hope to take part in the Advisory Board of

  • Thank you for your attention!
