IESR Content

• Descriptions of
• Collections of resources
• Informational Services that provide access
• Agents Owners / Administrators
• Transactional Services
• Supplied by resource providers
• Check by IESR content manager

IESR Entities
Collection
provides access
owns
Service
Agent
administers
5
IESR Identifiers

• Every entity has a URI
• Assigned on registration in IESR
• PURL-based Object Identifier (POI)
• Example
• http//purl.org/poi/iesr.ac.uk/105636559-25788
• Internal use local part of identifier only

6
IESR Entity Description

• Described by metadata
• Based on open standards
• Metadata defined by Application Profile
• Semantics
• Occurrence
• Searchable
• Data Supply as separate entities

7
IESR Collection Metadata

• Based on RSLP Collection Description
• Simplification for electronic resources
• Consistent with
• DCMI Collection Description Application Profile
• NISO MI Collection Description
• Links to other entities
• hasService Service (IESR id)
• Owner Agent (IESR id)

8
Vocabulary Encoding Schemes

• Defined in Application Profile
• Single backbone subject scheme
• Dewey Decimal Classification System
• Other common vocabularies supported
• iesrusesControlledList
• IESR defined list (extensible)
• terminology service item level search

IESR Service Metadata

• More than RSLP CD locator
• Bespoke IESR scheme
• Single access method
• Z39.50, SOAP, OAI-PMH, Web/CGI
• Location URL
• Interface property for some service types using
  appropriate schema
• Links to other entities Agent, Collection

Other Service types

• SOAP Locator access URL Interface WSDL
• SRU Interface ZeeRex
• SRW Interface ZeeRex WSDL
• OAI-PMH Locator BaseURL
• OpenURL Locator BaseURL
• Web CGI Interface arguments
• Web page Locator URL

13
Agent Metadata

• Agent name
• Agent description
• Contact details, address, URL
• Links to other entities
• owns Collection
• administers Service

14
IESR Administrative Metadata

• Included with every entity
• Data suppliers can include
• Internal creator/contributor, creation dates
• External source
• External IESR includes
• creating organisation, publisher (IESR)
• latest modification date
• rights to reuse descriptions

16
IESR Services

• Details on IESR web site
• Z39.50
• Search via Bib-1 attributes
• Results text (SUTRS) XML
• OAI-PMH for harvesting
• OpenURL Link-To Resolver
• Implements IESR identifier resolution
• Web Search and Browse
• Data supply Editor

17
Future Services

• Web Services SOAP / SRW (planned)
• RSS
• UDDI (under investigation)
• Prototype registry
• Mapping IESR data to UDDI
• Is there a requirement?
• Data ingest / harvest

18
IESR XML

• Composite Collection record via Z39.50
• Collection
• All services that provide access
• All agents
• Owners of collection
• Administrators of services
• Single entity record via OAI-PMH
• Simple Dublin Core for Interoperability

19
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.

20
Using IESR

• Portal
• amalgamated set of resources
• IESR provides
• Discovery of resource collections
• Up-to-date details of access to collections
• Using IESR Portal builder can
• Add new services to portal
• Provide metasearch

21
Portal Metasearch Scenario

• Social Science portal discovers collections with
  e.g. Z39.50 services
• Provides cross-search to end-user using e.g.
  Z39.50
• Portal builder doesnt need to know about all
  resources
• Users discover collections unaware of

22
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
• Conversion into local configuration file

23
MIMAS Metadatabase Use Scenario

• MIMAS Metadatabase is a catalogue of resources
  provided by MIMAS
• Metadatabase will
• Harvest changed IESR records nightly
• Select MIMAS records
• Update Metadatabase
• Staff have only one set of descriptions to
  maintain
• XML descriptions for other uses

24
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

25
Other Uses

• Portal Links to Web Search
• General resource discovery
• Reuse collection description
• Initially created by resource supplier
• Shared by multiple registries and applications
• RSS Aggregator (news data alerts)
• Personal digital library portal

26
Metadata Schema Use

• OCKHAM (US) Outcomes of NSF projects
• CETIS / DEST eLearning/Admin in Australia
• Standards development
• DCMI Collection Description
• NISO Metasearch Initiative
• DCMI Agents Working Group
• Stakeholder requirements
• Institution details
• eLearning

27
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?
• IESR collaboration with OCKHAM in US
• Sharing collection descriptions
• Need common metadata schema

28
IESR Future

• More and updated content
• New IESR services
• Demonstrating viable IESR use
• Persistence of content
• Maintenance of metadata schema
• International interest in Service Registries
