Building Content and Service Oriented Networks Slide_10 TF-LSD (LDAP Service Deployment) Directory is an important component of modern concept of service and content oriented networks Started from the LDAP BoF on 12 May 2000 in Amsterdam Follow-on of the DIRECT project on DIrectory REplication CoordinaTion TF-LSD main goals and deliverables –Directory indexing implementations based on the Common Indexing Protocol (CIP) –Definition of a European wide White Pages index service –Referencing between X.521 and DC-naming for distribution of knowledge information between LDAP servers –Pilot service for publishing, distributing, and validating certificates LDAP based storing, distributing and validating certificates –New evolving directory related standards (DSML, DEN, etc.)

Building Content and Service Oriented Networks Slide_11 TERENA Portal Project/Initiative Answer to vital needs of R&A community in specific Information service Platform for developing and piloting services for the European research and academia community –Showcase for new technology –Platform for NRN research activities combined with industry –Combines expertise of TERENA community in indexing/searching, caching/storage, streaming Started with REIS Initiative in June 1999 Currently being discussed with potential partners from industry –Opportunity with IBM Internet2 Centre in Zoetermeer / NL Work on common research objectives Facilities with excellent connectivity (155Mbps to SURFnet) –Inktomi –AltaVista

Building Content and Service Oriented Networks Slide_12 Portal components Research Indexing service –Indexing/Searching tools/engine –Cross-Searching Automatic Indexes and human-made Subject Gateways Directory services and Metadata –Automatic Classification –Metadata Registry Video-on-Demand and Streaming (plus hosting) Content Replication Portal as an access point to all what’s behind the Portal –All what community uses, develops and needs –Multilsite and multihome for services Collaborative vs Distributed vs Centralised

Building Content and Service Oriented Networks Slide_13 The TERENA Portal Concept Discovering Authoritative Source of Information Commercial Portals Subject Information Gateways Video Archives Institutional Web Pages Single Service Access Point

Building Content and Service Oriented Networks Slide_14 REsearch Indexing Service for Europe (REIS) REIS Initiative - started from BoF at TNNC’99 –Main goal - to build pilot service for Research and Education community in Europe Specific REIS features –Comprehensive coverage of Research-on-the-web –Both searchable and browsable by subject –Interactive search refinement Finding Authoritative Resources - ”Topic Distillation” –Adaptive crawling and automatic (pre-)classification of gathered data –Attribute (metadata) searching Dublin Core metadata search capability –Multilinguality and cross-language searching Multilingual support in interface

Building Content and Service Oriented Networks Slide_15 TERENA Portal goals Community oriented Portal –Binding and assisting specific community –Virtual community with its Knowledge accumulation and domain specific resources –Instant communication and IA / VPP Research diversification and knowledge accumulation Services/tools to assist Researchers and Educators –building authorities in new domains –discovering knowledge/resources in European/worldwide Internet –R&E Multimedia information Cooperation with industry –to help research community –to provide feedback and input from research community

Building Content and Service Oriented Networks Slide_16 What do people need from Research oriented Portal? Discussed on the Panel at WebIndexing Workshop in Delft May 2000 Information in specific research area –new and diverse areas not covered by existing classification and Subject Gateways (Virtual) Community interaction –Possibility to talk to expert (become bound into community) –to communicate with people –to find colleagues Video/audio materials –personalised experience Build personal profiles and exchange of experience and findings –Shared bookmark - to accumulate highly professional experience Access to Open Research area –Information discovery and expert tools –Automatic classification and knowledge mining

Building Content and Service Oriented Networks Slide_17 TERENA Portal as Community Oriented Portal To build successful Portal you need to find/build proper community –Community membership creates willingness to cooperate in resources and services creation and development Bottom-up vs Top-down approach Possibility to communicate between people (community members) –create cooperative environment –virtual (point of) presence Finding relevant resources in diverse areas Starting with specific area and specific services in general concept Ask and propose to users –user needs driven approach

Building Content and Service Oriented Networks Slide_18 TERENA Portal Value-Added Services Combined with communication between researchers –to explore common findings –building virtual community/presence Knowledge Accumulation and Dissemination Quality Information Resources enabled by “web-of-trust” Advertisement from and linkage to the Scientific publishers

Building Content and Service Oriented Networks Slide_19 Research oriented vs Commercial Portals - Conceptual Old Portal receipt –LSD – Logo-Search-Directory New flavors –myportal service and personal Mail address –Image search –Link to e-commerce TERENA Portal differences from commercial –Professional and Educational information Community oriented service Information consistency –Limited (professional) communities of trust Strong Authentication and Confidence Secure real-time communication – video and audio –Video and Audio Lectures, Seminars and Conferences –Intelligent Agent – like ancient “Librarian”

Building Content and Service Oriented Networks Slide_20 Multimedia/Visual Information in Education and Research Conferences video archives vs Conference Proceedings –Q&A – Parallel sessions – (Parallel conferences) Dedicated lectures/seminars – Ad Hoc topics –Lectures by expert specialists –Exchange with both teacher and auditorium Distance Education and Training –Courses on demand –Hands-on and practical lessons (e.g., surgery, fiber cabling, etc.) –Virtual classroom Distinctive features –Live video/speech –Information humanisation/impersonalisation –Still paper-like information vs train-of-thought –Virtual presence
