Iesr service metadata

IESR Service Metadata

  • More than RSLP CD ‘locator’

  • A few IESR properties to support discovery and registry application

  • IESR agnostic about protocol

  • Single access method / protocol:

    • SRU, Z39.50, SOAP, OAI-PMH, Web/CGI

  • Location URL

Digital Repositories, e-Research and Portals Workshop


Iesr service metadata continued

IESR Service Metadata (continued)

  • Prototype service type list

    • e.g. Alert, Harvest

  • Authentication details

    • Will investigate Shibboleth AAP

  • Interface property for some service protocols

    • Connection details

    • Uses appropriate schema

Portal in jisc ie

Portal in JISC IE

  • JISC defines a portal:

    A network service that brings together content from diverse distributed resources using technologies such as cross searching, harvesting, and alerting, and collates this into an amalgamated form for presentation to an end user.

Digital Repositories, e-Research and Portals Workshop


Using iesr

Using IESR

  • Portal

    • amalgamated set of resources

  • IESR provides:

    • Discovery of resource collections

    • Up-to-date details of access to collections

    • Discovery of transactional services

      • RSS

      • OpenURL resolvers

  • IESR will develop Use Cases

Digital Repositories, e-Research and Portals Workshop


Portal metasearch scenario

Portal Metasearch Scenario

  • Social Scientist: find resources about family health

  • Social Science portal discovers collections with e.g. Z39.50 services

    • Vocabulary service needed

  • Portal provides cross-search to end-user using e.g. Z39.50

Digital Repositories, e-Research and Portals Workshop


Iesr benefits for portal

IESR Benefits for Portal

  • IESR provides for:

    • Discover

    • Locate: access details in retrieved composite record

    • Invoke: interface ZeeRex connection details

  • Portal builder doesn’t need to know about all resources

  • Users discover collections unaware of

Digital Repositories, e-Research and Portals Workshop


Harvesting iesr

Harvesting IESR

  • OAI-PMH allows replication of IESR

  • Portal harvests IESR records

  • Caches locally for use by portal software, e.g.:

    • Local service registry

    • Knowledgebase after conversion to appropriate format

  • Scenario: portal for Open Access material in Institutional Repositories

Digital Repositories, e-Research and Portals Workshop


Mimas metadatabase use scenario

MIMAS Metadatabase Use Scenario

  • MIMAS Metadatabase is a catalogue of resources provided by MIMAS

  • Metadatabase will

    • Harvest changed IESR records nightly

    • Select MIMAS records and transform

    • Update Metadatabase

  • Staff have only one set of descriptions to maintain

  • XML descriptions for other uses

Digital Repositories, e-Research and Portals Workshop


E research scenario

e-Research Scenario

  • Bioinformatics researcher: find research literature about a cattle disease

  • Bioinformatics Portal builder discovers bibliographic collections with SOAP services, e.g. Zetoc

    • Vocabulary service needed

  • Portal builder plugs in bibliographic service

  • Researcher includes in workflow

Digital Repositories, e-Research and Portals Workshop


Use by portal builder

Use by Portal Builder

  • Discover resource and access details by Web interface

  • Handcraft resource into metasearch

  • Possible future Digital Library build software will automate process

  • SOAP services need manual intervention

Digital Repositories, e-Research and Portals Workshop


Other uses

Other Uses

  • Portal Links to Web Search

    • General resource discovery

  • Reuse collection description

    • Initially created by resource provider

    • Shared by multiple registries and applications

  • RSS Aggregator (news; data alerts)

    • Personal digital library portal

Digital Repositories, e-Research and Portals Workshop


Metadata schema use

Metadata Schema Use

  • OCKHAM (US): Outcomes of NSF projects

  • CETIS / DEST: eLearning/Admin in Australia

  • aDORe Digital Object Repository (LANL)

  • Australian Partnership for Sustainable Repositories: collection description service

  • Standards development:

    • DCMI Collection Description / Agents

    • NISO Metasearch Initiative

Digital Repositories, e-Research and Portals Workshop


Wider information environment

Wider Information Environment

  • Scope of IESR

    • JISC, UK, international?

    • Data ownership and maintenance

  • Distributed / federated model

    • Each node describes own resources

  • How to cross search?

    • Metasearch; UDDI; OAI-PMH harvest

  • IESR collaboration with OCKHAM in US

    • Replication by OAI-PMH; search local

Digital Repositories, e-Research and Portals Workshop


Iesr a registry of collections and services

UDDI

  • Standard for discovery and publicising of services on offer

  • Built prototype registry (UKOLN)

    • jUDDI / MySQL (JDBC)

    • Not a lot of software available

  • Mapping IESR data to UDDI

    • businessEntity – Agent (administrator)

    • businessService – conflate Service and Collection

      • Loss of rich collection detail?

Digital Repositories, e-Research and Portals Workshop


Uddi in ie

UDDI in IE

  • Is there a requirement?

  • Little evidence in Digital Libraries

  • Some use in eScience:

    • Grid Engineering Taskforce

    • Grimoires

      • Also richer RDF metadata

  • IESR UDDI view planned

    • Interoperate with other registries

    • But may be ‘lossy’

Digital Repositories, e-Research and Portals Workshop


Sharing descriptions

Sharing Descriptions

  • Sharing collection descriptions

    • Created by resource provider

    • Reuse with possible local augmentation

    • Needs common / derivable metadata schema

      • Standards: NISO Metasearch Initiative / DCMI Collection Description: provide common core

      • IESR a practical example application

  • Rights issues

    • Simplified with common CC licence

Digital Repositories, e-Research and Portals Workshop


Iesr future

IESR Future

  • More and updated content

  • New IESR services

  • Maintenance of metadata schema

    • Stakeholder requirements:

      • eResearch

      • eFramework

    • Standards development

Digital Repositories, e-Research and Portals Workshop


Iesr future continued

IESR Future (continued)

  • Demonstrating viable IESR use

    • Use Cases

    • JISC IE Test Bed Project

  • Collaboration with Service Registry development, UK and international

    • OCKHAM test bed experiment

  • Persistence of content
