overview

• status and starting point
• requirements in university and industry
• criteria for a technical solution
• identical requirements gt transfer of both
  know how and experiences
• information management
• results conclusion outlook

3
starting point
information documentation, catalogues, programs,
drivers, faqs, lecture notes, teaching/learning/t
raining material, CBT applications, web pages,
video, audio, animationen hypermedia information
producer
consumer
4
resultat chaos

• static links
• dead links
• orphans
• unrecognisable referential or organisatorial

5
cost/benefit
hypermedia information documents like spaghetti,
no versioning, one way communication,all or
nothing access, ww search intended?
consumer
producer
6
deficits

• lack of clearness, lucidity (detail/overview,
  context, topicality)
• recherche?
• lack of flexibility (only owner modifies)
• little interactivity (read only, e-mail)
• no user- and object-specific access rights
• no collaboration support (shared editing)
• costly maintenance and administration

where to find what is looked for ...
7
requirements

• structure instead of chaos
• controlled access
• interactivity
• recherche
• management tools
• link-consistency

8
criteria

• information system as a structured information
  base, providing hypermedia informationto
  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

9
transfer

• 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

10
install, deployment

• a system 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)

11
maintenance
to be guaranteed/maintained

• 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

conclusion
results (in university)

• WebLearn server teaching/learning material,
  lecture notes, programs, virtual work shops for
  projects, working groups etc
• see e.g. www.weblearn.hs-bremen.de/risse
• higher education teleteaching

results (transferable to industry)

• Hyperwave satisfies the technical criteria for
  information and communication systems
• maintenance and user training are indispensable
  for productive, continous and sustained
  operation of information and communication
  systems
