OpenURL v1.0 Registry

• Entities in OpenURL
• Referent (the referenced work)
• Resolver (the OpenURL resolver/link server)
• Referrer (the information source)
• ..and (through pid, etc)
• Requester (the user)
• Referring Entity (e.g. citing Article)
• ServiceType (what is requested)

• Entities in OpenURL
• Referent (the referenced work)
• Resolver (the OpenURL resolver/link server)
• Referrer (the information source)
• Requester (the user)
• Referring Entity (e.g. citing Article)
• ServiceType (what is requested)

Context Object

• Descriptors
• Identifiers
• By-Value Metadata
• By-Ref Metadata
• pid

• Encoding
• key/value (querystring)
• PL, XML
• Others

• Transportation
• HTTP GET/POST
• Others (SOAP OAI-PMH)

See web services demonstration

Metadata planes
An OpenURL Resolver allows users access to an
extended service plane.
See SFX demonstration

Resource List Interoperability

• Specifications for the exchange of structured
  metadata between systems that provide resources
  on the one hand and those that harvest and
  organize those resources for pedagogic purposes
  on the other
• Deliverables
• RLI Information Model Document
• RLI Binding Document A Resources List XML
  binding will be defined.
• RLI Best Practices Document The best practices
  will include the following
• Definition of transport protocols. It is
  expected that a DRI/Web Services model will be
  used.
• System behaviors. These will be defined in a
  WSDL binding.
• Item-specific association of Resources within
  Library Systems to Resources Lists.
• RLI Conformance Document Conformance with the
  RLI spec will be clearly defined in a separate
  document.

Learning Objects and Learning Object Metadata

Prospects for the future

• Investigate how ParaTools could be used to
  populate Resource XML instance documents that
  conform to new IMS standards
• Build more sophisticated SOAP messaging between
  OpenURL Resolver and Digital Object Repositories,
  according to IMS DRI standards i.e. XQuery and
  SOAP
• Investigate how Shibboleth or an OKI service
  definition could be used to authenticate user
  access
• Investigate how real time payment could be
  built into architecture, (maybe exchange of
  credits or acknowledgement).
• Integrate novel Semantic Web ideas e.g. digital
  repository metadata visualisation

Functional Components of the Semantic Web

Key issues

• Identifiers for Learning Objects
• Digital Rights Management
• Cultural change BUILDING E-LEARNING COMMUNITIES

Learning more about the OLIVE Project

• Two papers will be produced late August
• A report that explains exactly what weve done on
  the OLIVE project with enough details for anyone
  to continue developing the types of services
  weve started creating.
• 'The Appropriate Copy Problem and Learning
  Objects problems and prospects
