Conception of Educational Resources Organization and Access Management for Virtual University :  Conception of Educational Resources Organization and Access Management for Virtual University Ukrainian Institute for Information Technologies in Education (UIITE) Technical University of Ukraine 'Kyiv Polytechnic Institute' (NTUU'KPI') http://udec.ntu-kpi.kiev.ua e-mail: vv@udec.ntu-kpi.kiev.ua Authors: Vyacheslav Valuisky Inna Malyukova Michael Goncharenko Report Activities:  Report Activities Modern University educational resources organization and an access management; Analysis of worldwide activities, principal directions; Concept of software model for intra-university and inter-universities education support. Report Main Tasks :  Report Main Tasks To analyze a main set of web-oriented virtual services which need to be accessible for modern (virtual) university students and staff. To analyze and to determine principal points in line to design of virtual university software architecture. To analyze progressive worldwide solutions for above items. To make recommendations. Modern University Educational Resources Organization (typical):  Modern University Educational Resources Organization (typical) Virtual Laboratories Virtual Knowledge Centers Digital Libraries Research Projects Educational Projects Web Content Management System Internet Full Screen Video Conferences Computer Testing System E-Learning Platforms Authoring Tools Off-Line Client Distance Course SCORM format Technical University of Delft (Netherlands) Principal Points in Line to Design of Virtual University Software Architecture.:  Principal Points in Line to Design of Virtual University Software Architecture. A Single Sign-On authentication via Web for every user to all distributed restricted educational resources. Web authorization for every user to access all distributed restricted educational resources. Definitions:  Definitions Authentication – a registration of user for an access to resource as usually with login and password or other identifiers : smart-cards, certificates, etc. Authorization – assignment of different rights for every user to access a resource (i.e. student, tutor, administrator, etc.) Why these Principal Points are Selected:  Why these Principal Points are Selected - Individual authentication and authorization for an every educational resource requires: -a lot of different logins and passwords for every user; -a lot of logins and passwords for all users; -administrators complicated support; -a lot of repositories; creates problems: -with inter-institutional and intra-institutional access to educational resources; -with development of e-learning using inter-institutional links; -with a virtual university organization What we’ll get :  What we’ll get -a single login and password for user to access all educational resources; -easy inter-institutional and intra-institutional access to resources; -transparent organization of e-learning using inter-institutional links Internet2+IBM ProjectShibboleth +WebISO model:  Internet2+IBM Project Shibboleth +WebISO model Shibboleth: is a web-based inter-institutional Single Sign-On (SSO) authentication and attribute exchange mechanism for an access to educational resources. WebISO: is a web-based intra-institutional SSO authentication for an access to educational resources http://shibboleth.internet2.edu/ http://middleware.internet2.edu/ http://www.a-select.org http://www.projectliberty.org/ Shibboleth joints 262 Universities in the U.S.A. A-Select (compatible with Shibboleth) has 150,000 users in higher education of the Netherlands in 2005 Liberty joints 150 global organizations currently Open Source software oriented A-Select:  A-Select A-Select uses as a standard authentication platform in the Netherlands. There is designed initially as a commercial product. From 2004 A-Select is open source. Compatible with Shibboleth. There are three product lines: A-Select Basis (a continuation of the current implementation); A-Select Components (additional functionality such as attribute acquisition and authorisation); A-Select Next Generation (NG) - research and development of the new A-Select platform.

What we plan:  What we plan To start experiences with completely shibbolized e-learning platform OLAT; To use UIITE LDAP repository for experiences with Shibboleth; To create a local Shibboleth Federation for test purposes on a base of UIITE; To learn possibilities of Netherlands National system A-Select at Delft Technical University during a visit to Delft from Feb.18 through March 05, 2006. Conclusion:  Conclusion Shibboleth (Internet2+IBM) project may be recommended as a basic for development of virtual university architecture or any other distributed web-oriented educational organization; Shibboleth allows to use web-based Single Sign-On (SSO) for Inter-Institutional and Intra-Institutional access to educational resources and facilitates all procedures for modern education support; Shibboleth is supported by modern commercial e-learning platforms; Shibboleth is oriented for using of open source software; Shibboleth allows to use different types of distributed architectures for web-oriented learning; Shibboleth is most progressive technology in line to education support in modern university or any virtual university.
