Climbing the Slope of Increasing Realism

LSE for You – the story continues…

Chris CobbJohn Paschoud


The story so far….


In the beginning….

“building on the fly…..”


Slide 6, July 20th 2004Climbing the slopePEPC 2004, Nottingham

Getting our feet on the ground…• Coordination between key internal partners• A plan…• A budget…• A vision of what the users wanted…• An identification of the problems to be

solved…• An architecture to solve them…

The Middleware Dilemma

•When it’s working, nobody sees it

•When it’s broken, EVERYTHING’s broken!


Recognising some common goals• JISC AAA Programme

– LSE SECURe Project– Shibboleth Authentication & Authorisation protocols

• JISC strategy:– Middleware appears under Aim One:

“To develop solutions that help the UK education and research communities to keep their activities world class through the use of ICT.” (1.4 a middleware service)

– Meets Key Performance Indicator: “Develop a common, integrated information and communications environment.”


JISC Common Information Environment

Powell, A, July 2003 (from UKOLN website)


PERSEUS ProjectPortal-Enabled Resources via Shibbolized End-User Security

• Extending Shibboleth to provide a test vehicle for policy-driven target authorisation decisions

• Shibboleth-based access-management to information resources via an institutional portal, using uPortal toolkit– SigNet?– PERMIS?

• Authority management for “short-term virtual organisations”– LSE Alumni Special Interest Groups


PERSEUS Project• Follows-on from JISC SECURe Project at LSE• JISC funding: £250K ($450K) over 2 years

– July 2004 to June 2006• Part of JISC Core Middleware:Technology Development

Programme– …fitting within JISC Common Information Environment

• Using LSE as a testbed– Users (‘only’ about 10K directory identities)– Infrastructure – Resource licenses

• Producing:– Documented, scaleable campus models– Contribution to OSS developments of uPortal and SigNet

More than one portal?

• Bi-lateral short-term courses– LSE-Columbia DART Anthropology teaching project

• Regional resource-access deals– InforM25 London libraries

• National content licenses– EDINA, MIMAS data services

• Trans-national consortia– NEREUS portal for European Economics Research

Portal interop scenarios

Regional inter-library portal:

InforM25(London regional libraries ‘clump’)

Subject-specialized research portal:

Alumni groups as Virtual Organisations

• 2,500/year registered with LSE Library• 4,000 alumni email accounts• Special interest groups

– (e.g.) LSE Lawyers Group– (e.g.) American Friends of LSE– Self-administering– Semi-autonomous– Loose contractual relationships– …but politically highly significant / powerful


Alumni groups as Virtual Organisations

• How can we model their (limited, but highly-valued) rights of access to restricted resources?

• …without compromising the value of ‘full member’ status for current staff & students

• …or our licence conditions for commercial resources

• How can we manage their dynamic nature?• …or do we trust them to do that themselves?


PERSEUS relationships


Involving real people

• Service providers• Resource owners• Students• Academics-as-teachers• Academics-as-researchers• Academics-as-decision-makers

Bringing Everyone Together

At times it felt like …..


Climbing the slope of increasing realism

• Focus groups, focus groups, focus groups• Straw poll• Training• Budget negotiations• Compromise• Student Experience


Making the business case– killer apps.

• cv builder• reference writer• simple student record• simple budget report


A long slow gentle incline……
