MIDDLEWARE
• JISC Core Middleware requirements can be
summarised as follows:
• An access management solution that will solve
access to internal resources (e.g. computer
facilities, exam papers) as well as external
resources.
• Need for support for long-term stable
collaborations between institutions, particularly
collaborative e-learning scenarios.
• Need for support for ‘ad-hoc’ collaborations
between groups of researchers (‘virtual
organisations’).
• Continued need for support for access to external
resources, preferably via a ‘single sign-on’.
Supporting further and higher education
INTERNATIONAL
CONTEXT
• A number of countries have launched
national programmes to roll out middleware
within research and higher education
• Already some major schemes which target
the whole population within these
communities, for example, authentication
and authorisation schemes for access to
digital context
• Now facing imminent issues in extending
these schemes:
– inter-working between schemes, to move
from national to international coverage
– expanding federations of trust
– not principally technical issues
• Malcolm Read and Ken Klingenstein
proposed an international meeting to try to
define a way ahead
Supporting further and higher education
INTERNATIONAL
MIDDLEWARE EVENT
• Hosted by JISC
• Representatives invited from countries which
have committed funding to a comprehensive
national programme
• Attended by representatives from Australia,
Finland, Netherlands, Spain, Switzerland, UK,
US and CERN
• Aims:
– to establish framework for further
international collaboration of authentication
and authorisation systems, leading
– to interoperable user mechanisms, and
– to help other countries develop similar
large-scale systems
Supporting further and higher education
GLOBAL INTERWORKING OF
NATIONAL SCHEMES
• Most schemes (‘federations of trust’) are
limited to one country
• The network peering model is relevant to
extending coverage
• Set of criteria needed to judge whether to
accept a ‘candidate’ federation
• Key Action: production of a ‘cookbook’ to
describe the criteria and the selection
process
Supporting further and higher education
THE COOKBOOK
• The cookbook should contain
– guidance on practical issues of setting
up a scheme
– criteria for judging the quality of a
scheme
– design of structures to underpin
governance and management
– examples of successful
implementations
• The cookbook should also help those
countries planning to set up a scheme for
the first time
• It was agreed that the first version of the
cookbook should be produced on a short
time-scale
Supporting further and higher education
OUTPUTS
• On behalf of the organisations attending, it
was agreed to fund:
– the authoring of the cookbook
– a full-time facilitator for one year initially
• Both of these will be actioned immediately:
the timescale for the production of the
cookbook will be short.
• These initial actions may be extended in
conjunction with other interested parties.
• The estimate costs of the initial actions is
about €150K.

THE UK E-SCIENCE
PROGRAMME
• In November 2000 funding for UK e-Science
programme was announced, with allocations
to programmes within each of the Research
Councils
• Core e-Science Programme develops and
brokers generic technology solutions and
generic middleware to enable e-Science.
• The Core e-Science Programme is managed
by EPSRC on behalf of all the Research
Councils.
• Example project – DAME
http://www.cs.york.ac.uk/dame/

DAME (Distributed Aircraft
Maintenance Environment)
• EPSRC Funded, £3.2 Million, 3 years,
commenced Jan 2002.
• UK pilot project for e-Science
• Aims to show the utility of Grid
computing for data and compute
intensive engineering problems
• A generic system applicable in many
domains
Supporting further and higher education
DAME PARTNERS
• 4 Universities:
– Universities of York, Sheffield, Oxford,
Leeds
• 3 Industrial Partners:
– Rolls-Royce
– Data Systems and Solutions
– Cybula Ltd

DEMONSTRATOR
OBJECTIVES
The DAME demonstration system provides a
diagnosis workbench (portal) which brings
together a suite of analysis services via Grid
technology:
– Provides access to a range of analysis
tools for the engine diagnosis process
– Will act as central control point for
automated workflows
– Manages issues of distributed diagnosis
team and virtual organisations
– Manages issues of security and user
roles.

DAME GRID
CHALLENGES
• Building ‘proof of concept’ for Grid
technology in the aerospace diagnostic
domain.
• Two primary Grid challenges:
– Management of large, distributed and
heterogeneous data repositories;
– Rapid data mining and analysis of fault
data;
• Other key (commercial) issues:
– Remote, secure access to flight data and
other operational data and resources;
– Management of distributed users and
resources;
– Quality of Service issues (and Service
Level Agreements)
Supporting further and higher education
e-RESEARCH AGENDA
• Significant infrastructure challenges:
– creation of a ‘multidisciplinary research
environment’ for research-intensive
universities (see VRE slides)
– mechanisms to systematically collect,
preserve and make available digital
information
Supporting further and higher education
e-RESEARCH AGENDA
(continued)
– need for a ‘national e-infrastructure’ to
support the research community: SJ5 will
provide a network infrastructure to support
researchers’ sustained, high capacity data
transfers, and also facilitate collaboration
across education and research
– need to encourage young people to study
science subjects: JISC funded three pilot
projects to provide school students access
to some of the most advanced scientific
applications currently available
Supporting further and higher education
VIRTUAL RESEARCH
ENVIRONMENT (VRE)
• VRE aims to help researchers in all
disciplines manage the complex range of
tasks involved in research
• Standards-based, service-oriented
architecture
• Integrated functionality
• Managed / secure / sustainable
• Usable and accessible
• Personalised
• ‘Agent-assisted’ / ’Intelligent’
• Extensible
• Collaborative
• Portable / ubiquitous access

TEXT MINING
• Text mining attempts to discover new information
by applying techniques from data mining,
information retrieval, and natural language
processing:
– identifies and gathers relevant textual sources
– analyses these to extract facts involving key
entities and their properties
– combines the extracted facts to form new facts
or to gain valuable insights
– finds applications in diverse areas of wide
interest such as drug discovery and predictive
toxicology, protein interaction, competitive
intelligence, protection of the citizen,
identification of new product possibilities,
detection of links between lifestyle and states
of health
Supporting further and higher education
NATIONAL UK CENTRE
FOR TEXT MINING
• Jointly funded by JISC, BBSRC and EPSRC
• Based at University of Manchester, in
partnership with the Universities of Liverpool
and Salford. International partners include
University of California at Berkeley, University
of Geneva, University of Tokyo, and the San
Diego Supercomputer Center
• A number of aims (see next slide)

e-LEARNING
FRAMEWORK
• Development of a common technical
framework
• Open source
• Will facilitate the integration of commercial,
home-grown and open source components,
and applications within institutions and
regional federations by agreeing common
service definitions
Supporting further and higher education
ELF PROJECTS ARE
DEVELOPING
• Web Service Definitions for component
services
• Implemented in Web Service Toolkits
– Service and client ‘adapters’
– Mainly in Java and .NET, with
standardised APIs
– Derived from the Web Service Definition
Language
• Open Source
– Liberal ‘commercial use’ licenses
– Encourage wide adoption of
specifications
• Service definitions submitted to
specification bodies
– IMS only e-Learning body developing Web
Service specifications.
