BACK TO THE FUTURE
The problem is:CRISs are not much used compared with other
information sourcesBecause:(a) they are difficult to use (different from everything else at
client workstation)(b) the data quality is insufficient - timeliness, completeness(c) they do not integrate easily with other information
sources(d) they do not integrate easily with local office environmentSo:
They are just not sexy !
From CRIS1998
![Page 6: 1 CRIS: Research Organisation View of the e-Infrastructure Keith G Jeffery STFC Anne Asserson UiB](https://reader038.vdocuments.us/reader038/viewer/2022103123/56649d225503460f949f89b1/html5/thumbnails/6.jpg)

• CRIS91: advocated electronic documents Quality– use of electronic forms for input – electronic documents for output
• CRIS93: advocated use of WWW Availability– easy-to use UI– ubiquitous– UI integration with other information sources and desktop
• CRIS95: ‘CRIS emerging into the light’ Integrated– WWW for client environment compatibility with office systems– workflow and cscw for document (e-forms, reports) management– resolving heterogeneity in information access (by metadata)
BACK TO THE FUTURE
Recapitulation of proposals from earlier CRIS conferences
From CRIS1998

BACK TO THE FUTURE
• At CRIS 1998 advocated the use of metadata as the key to ensure CRIS are integrated with their environment– With office environment– With WWW for easy access to information– With workflow for quality input– With other systems in the organisation– With other CRIS (interoperation)
• But it just did not happen!

CRIS2008
• 10 years on are we – the euroCRIS community - in danger again of missing out by not constructing CRIS such that they are ‘sexy’?
• This presentation introduces an architectural vision and proposes an action plan to place CERIF-CRIS at the centre of modern ICT environments

Why is this important?• e-science (or more generally
e-research)
• e-infrastructure concept adopted by the EC
• architecture adopted by the NESSI ETP
• ETSI (European Telecommunications Standardisation Institute)
• most advanced research now done using this environment: particle physics, molecular biology, astronomy, materials science, physics, chemistry, geoscience, meteorology, environmental science, social science, economics / econometrics, history……
• and linked (ESFRI) with research infrastructure e.g. large facilities, databases etc
• (European Technology Platform) – major European ICT players
• aiming to standardise – Special Group on GRIDs (Mike Fisher, BT)
This infrastructure was initiated in the community we serve and is evolving from R&D to business

43
Middleware and SOA
• Middleware is usually constructed using SOA (Service Oriented Architecture) techniques
• Each service is discrete with a clearly defined function
• It is described by metadata which covers its functional and non-functional properties
• Services can be composed (orchestrated, choreographed) into larger units– based on their metadata
SOA replaces ad hoc interfaces between systems with a consistent architectural style
![Page 44: 1 CRIS: Research Organisation View of the e-Infrastructure Keith G Jeffery STFC Anne Asserson UiB](https://reader038.vdocuments.us/reader038/viewer/2022103123/56649d225503460f949f89b1/html5/thumbnails/44.jpg)

CERIF-CRIS and SOA
• So we need to construct CERIF-CRIS so they can fit into this architecture
• There are two tasks:– Define the metadata to describe the services– Define the services (functions and their non-
functional properties) required in a CRIS environment

Metadata for Services
• Just as data, information, documents can be characterised by metadata
• So can software (as services)
• And hardware• And combinations can be
wrapped together to form composed services (e.g server plus software plus information)– E.g. institutional repository– E.g. finance system
User Interface
A composed service

Intelligent Hyperactive Objects
• Hyperactive combines both – hyperlinking – active properties of a (grey) object.
• Hyperlinking implies multimedia components linked to form the object and also external links to other resources.
• The term active implies that objects do not (only) lie passively in a repository to be retrieved by end–users. They ‘get a life’ and the object moves through the network knowing where it is going.

A utility is a directly and immediately useable service with established functionality, performance and dependability, illustrating the emphasis on user needs and issues such as trust
Services are knowledge-assisted (‘semantic’) to facilitate automation and advanced functionality, the knowledge aspect reinforced by the emphasis on delivering high level services to the user
Service-Oriented Knowledge UtilityNGG3
The architecture comprises services which may be instantiated and assembled dynamically, hence the structure, behaviour and location of software is changing at run-time;

Take-Home Message #3
There are exciting developments in R&D that can make it easier to use the infrastructure for purposes concerning research.
CERIF-CRIS is exactly in line with these developments: get on the ‘train’ now because it is soon leaving.
![Page 65: 1 CRIS: Research Organisation View of the e-Infrastructure Keith G Jeffery STFC Anne Asserson UiB](https://reader038.vdocuments.us/reader038/viewer/2022103123/56649d225503460f949f89b1/html5/thumbnails/65.jpg)

Wake-up Call (again)
• The glimpse of the future is being developed now in the EC Framework 7 Programme– Challengers, 3S
• 2008: 10 years on from 1998 are we – the euroCRIS community - in danger again of missing out by not constructing CRIS such that they are ‘sexy’?
![Page 67: 1 CRIS: Research Organisation View of the e-Infrastructure Keith G Jeffery STFC Anne Asserson UiB](https://reader038.vdocuments.us/reader038/viewer/2022103123/56649d225503460f949f89b1/html5/thumbnails/67.jpg)
67
What Should We Do?
• We need to get ‘to the starting line’ so that CERIF-CRIS can be in the mainstream
• Step 1 is to use CERIF as information (for CRIS) and as metadata (for integrating other information)– Because it has formal syntax and defined semantics
• Step 2 is to define and create a set of services (SOA) to allow composition of higher-level services dynamically to satisfy the user requirements of CRIS and associated systems– So that the architecture is compatible with the developing
infrastructure
![Page 68: 1 CRIS: Research Organisation View of the e-Infrastructure Keith G Jeffery STFC Anne Asserson UiB](https://reader038.vdocuments.us/reader038/viewer/2022103123/56649d225503460f949f89b1/html5/thumbnails/68.jpg)
68
Work to be done: Metadata
• Provide a strawman proposal for metadata for services, objects– Based on schema / navigational / associative
(descriptive, restrictive, supportive)
• Gain general agreement• Test in use-cases• Revise as necessary• Standardise (ETSI, W3C) euroCRIS should be active in this to ensure
CERIF-CRIS well-represented in the ICT infrastructure
![Page 69: 1 CRIS: Research Organisation View of the e-Infrastructure Keith G Jeffery STFC Anne Asserson UiB](https://reader038.vdocuments.us/reader038/viewer/2022103123/56649d225503460f949f89b1/html5/thumbnails/69.jpg)
69
CRIS Services
• The requirement is to define a set of services related to a CERIF-CRIS for its maintenance and use
• The obvious start-point is the relational algebra– Select, project, difference, union, join, update– Because it is formally defined and based on theory– And because it expects information to be in FoL
• Supplemented by functions for– Reporting, statistical analysis, prediction/simulation
• And for – interoperation

Forward to the Future
• euroCRIS must seize this opportunity– Propose a metadata definition for services
and objects– Propose the set of services required for a
CRIS environment
• And so define CERIF-CRIS at the centre of the research environment across the e-, i-, k- infrastructure
