Contents Based on main headings in the study… • general issues • provision • fusion • presentation • shared infrastructure Joint JIIE/JCS Meeting

JISC IE and Google http://www.ukoln.ac.uk/distributed-systems/jisc-ie/arch/ie-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 Joint JIIE/JCS Meeting

General issues • service oriented ‘frameworks’ • maturity of the JISC IE • manual vs. automated approaches • semantic Web • community-driven activities • p2p Joint JIIE/JCS Meeting

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? Joint JIIE/JCS Meeting

Shared services issues Note: I’m not going to talk about AAA • 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 Joint JIIE/JCS Meeting

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’ Joint JIIE/JCS Meeting
