Tech.), Mary Fran Yafchek (SURA), Marcus Buchhorn (ANU) and others. (www.vide.net) Focus now on videoconferencing and video-on-demand for their middleware requirements Significant component of NSF Middleware Initiative (NMI)

A Map of Middleware
Core Middleware Areas Identifiers - syntax, semantics, reuse and reassignment policies Authentication - best practices for I and A, Web-ISO, Shibboleth Directories - structures, objectclasses, metadirectories, large-scale directories, resource discovery, interrealm, groups Authorization - access control mechanisms, Shibboleth PKI - for encryption, authentication, signing
Identity Services on One Slide Objectclass standards (e.g.eduPerson, gridperson, eduOrg) Content Portals Shibboleth exchange of attributes Future PKI DODHE et al Grids et al Interrealm Learning Management Systems Security Domain Personal Portals Video client Web services and servers Enterprise video dir WebISO Enterprise directory Campus authentication Future PKI
NSF Middleware Initiative Three year cooperative agreement between NSF and two teams: Internet2/EDUCAUSE/SURA GRIDs Center Goals are to promote a consistent and comprehensive middleware infrastructure that enables science and research and assists in a wider deployment throughout the higher ed community First year targets: Directories Security Videoconferencing
