JISC IE and Google
• previous paper considered relationships between JISC IE and Google:– complimentary rather than alternative
approaches– develop guidance for exposing content to
Google– investigate use of Google APIs– special treatment for community’s ‘high-
quality’ material – c.f. Google Scholar– encouraging use of OpenURLs by academic
and commercial content providers

now: expose separate simple objects (metadata only)
future: expose complex objects (metadata and full text)

Provision layer issues
• the ‘R’ word• complex objects• metasearch vs. full-text indexing• simple search interfaces• identifiers
Do I make my content available for indexing by Google or do I make my metadata available
for harvesting using OAI-PMH? Do I support Z39.50 or SRW?
What do I do about OpenURLs?

identifier used to identify?
Has this resource already been assigned an identifier?
How do I resolve this identifier?

Presentation layer issues
• the ‘P’ word• the other ‘P’ word• OpenURL ‘link servers’
– making openurl.ac.uk work globally– making OpenURLs work as URIs
Why do I need a portal when I’ve got Firefox, Google and my favourite RSS channel
reader installed on my desktop?

Shared services issues
• distributed service registries• metadata schema registries• identifier services• terminology services• licensing services
– who’s using what licences?– ensuing persistence of licensing agreements?
• automated metadata-generation tools• name authority services

Conclusions
• the study makes 26 suggestions – too many to consider here – but general need to recognise that…– our services are not (and will never be) the sole focus
of the end-user’s attention– our services fit into broader fabric of the Internet –
therefore need to be able to be integrated by others– some things are better done by others– possible tension between Web-based ‘portal and
browser ‘desktop application framework’ approaches– need to align eLeaning and ‘digital library’
