Institute for Informatics and Automation Thomas Risse: Hypermedia Information and Communication Platforms 8 information system as a structured information base, providing hypermedia information to specific users or user groups in a controlled way communication system supporting collaboration (team work, cscw, work flow, group ware... concepts) client multi server architecture browser supported interface (to minimize training) platform independent (hardware, os, browser) tools criteria

Institute for Informatics and Automation Thomas Risse: Hypermedia Information and Communication Platforms 9 Basic Support for Cooperative Work, GMD Lotus Notes, IBM Hyperwave, Hyperwave Information Management Hyperwave keeps/manages documents and links in a data base distributed data base on heterogeneous servers users navigate in a virtual document hierarchy user specific access (attributes) bidirektional links guarantee link consistency tools for administration, management, security, upload, backup transfer

Institute for Informatics and Automation Thomas Risse: Hypermedia Information and Communication Platforms 10 install, deployment a s ystem is only as useful as its tools: Hyperwave offers upload, modify, link wizards search wizard (attributes, full text, synonyms, variants,...) query object wizard (subscriptions, agents) rights wizard (views), back up wizard etc collaborative authoring (multiple clusters, annotations) multi linguality, diverse formats (alternative clusters) version control, validity/expiration date highly configurable (e.g. user preferences)

Institute for Informatics and Automation Thomas Risse: Hypermedia Information and Communication Platforms 11 lucid, obvious structure of the information base, extendable/enlargable in an apparent and unique way topicality, release/expiring date security (privacy) by adequate access rights (as open as possible, as strict as necessary) security (usage) by logic consistency data security by back up accounting maintenance to be guaranteed/maintained:
