  1. OHS7 - The Seventh Workshop on Open Hypermedia Systemsat Hypertext 2001, Aarhus Sigi ReichSalzburg Research / SunTREC sreich@salzburgresearch.at

  2. Overview • About OHSs • A view on the history of OHS workshops • Potential new directions • Programme of today's workshop ... • Wrap up

  3. About OHSs • OHS is short for Open Hypermedia System, i.e., a hypermedia system which is open with respect to several dimensions (Davis, 1996) • An OHS is typically composed of a set of middleware components which integrate between frontend (the clients) and backend (the servers) • Today's OHSs serve multiple hypertext application domains (navigational HT, spatial HT, taxonomic HT, etc.); they are referred to as component-based OHSs (Nürnberg, 1998)

  4. History of OHS Workshops • OHSs started in 1994 (with a Workshop on open HyperTEXT in Konstanz, and a Workshop on open HyperMEDIA in Edinburgh) • The Open Hypermedia Systems Working Group (OHSWG) formed in April 1996 • WWW site: http://www.ohswg.org/ • Mailing list: ohs@csdl.tamu.edu

  5. The New Web Site http://www.ohswg.org/

  6. The OHSWG • Goals of the OHSWG • "maximize the applicability of the last decade of hypermedia systems and infrastructure research" (Nürnberg, "old" OHSWG web site) by • creating a (visible) community • defining standards (protocols, APIs, reference architecture, etc.) • demonstrating interoperability • organising workshops and working group meetings

  7. The OHS Workshop Series  Started as the Open Hypermedia Systems Workshop OHS 1 (Edinburgh, 1994)  OHS 2 (Washington, 1996)  OHS 3 (Soton, 1997)  OHS 4 (Pittsburgh, 1998)  OHS 5 (Darmstadt, 1999)  OHS 6 (San Antonio, 2000)  OHS 7 (Åarhus, 2001) OHS 2.5 WGM (Soton, 1996) OHS 3.5 WGM (Åarhus, 1997) OHS 4.5 WGM (Soton, 1998) OHS 5.5 WGM (Esbjerg, 1999)  OHS 6.5 WGM (Åarhus, 2001)

  8. Statistics on the OHS Workshop Series

  9. Topics of OHS7 (see the CFP) • Interoperation and standardisation issues in OHS, including architectural issues, protocols, naming, transformation, etc. • Semantic Web including topic maps, meta data, ontologies, etc. • Document models and hypertext • Media aspects of OHSs such as synchronisation of contents and link data, streaming of links, etc. • OHS issues and Computer Supported Cooperative Work (CSCW) • Application scenarios, experiences, hypertext domains, and requirements for OHSs • Open Hypermedia on the Web • Presentation aspects including personalisation, context awareness, etc.

  10. Potential Directions 1/3 • Middleware Challenges (Geihs, 2001) • Enterprise application integration • Quality of service (QoS) • Nomadic mobility • Ubiquitous computing • Programming models (client-server, asynchronous interaction, mobile code, etc.) • Architecture (distribution transparency, layering, etc.) • Dynamic configuration (disconnected operation, adaptive applications (was "QoS"), ad hoc networking, etc.)

  11. Potential Directions 2/3 • ACM Multimedia Workshop on Multimedia Middleware (Plagemann, 2001) • Streaming Services • QoS Middleware • Configuration and Flexibility

  12. Potential Directions 3/3 • Middleware Challenges • Enterprise application integration • Quality of service • Nomadic mobility • Ubiquitous computing • Programming models (client-server, asynchronous interaction, mobile code, etc.) • Architecture (distribution transparency, layering, etc.) • Dynamic configuration (disconnected operation, adaptive applications (was "QoS"), ad hoc networking, etc.) • Hypermedia Middleware Challenges • Enterprise application integration • Quality of service for links / meta data • Nomadic mobility mobile link servers? • Ubiquitous computing • Dynamic configuration (disconnected operation, adaptive applications, ad hoc networking, etc.) • Programming models (design patterns, ???) • Architecture • Collaboration • Media aspects (CBR, CBN, etc.)

  16. Wrap up of the Workshop • The Proceedings • Questions and Issues

  17. The Proceedings 1/2 • Title and affiliations: have a look at the guidelines http://www.springer.de/comp/lncs/authors.html • Quotes: use proper quotes, in LaTeX this means ``quoted text'' (the opening quote reads like 66, the closing quote like 99) • Headings & title: all words in headings should be capitalised except for conjunctions, prepositions (e.g., on, of, etc.) and definite and indefinite articles (e.g., the, a, etc.) unless their appear at the beginning. • Page numbering and running heads: do NOT use a running title! This will be added later (in the final version). Also, do NOT use page numbering.

  18. The Proceedings 2/2 • Citations & references: the list of references is headed "References" and is not assigned a number. For citations in the text use square brackets (e.g., [1], [47, 48]). Examples 1. Baldonado, M., Chang, C.-C.K., Gravano, L., Paepcke, A.: The Stanford Digital Library Metadata Architecture. Int. J. Digit. Libr. 1 (1997) 108 - 121 2. Bruce, K.B., Cardelli, L., Pierce, B.C.: Comparing Object Encodings. In: Abadi, M., Ito, T. (eds.): Theoretical Aspects of Computer Software. Lecture Notes in Computer Science, Vol. 1281. Springer-Verlag, Berlin Heidelberg New York (1997) 415 - 438 • Incorporate FEEDBACK from Workshop! • Send me your final paper until BEGINNING OF SEPTEMBER 2001!!! • Thank you!!!

  19. Questions/Issues • This presentation will be available at the workshop site http://www.salzburgresearch.at/suntrec/ohs7/

  20. The OHS Workshop Series • Some good things ... • strong interest • feeling of a community (incl. visibility) • refereeing and publication • ... and things to be improved • more discussions • more focus

  21. Moving on • Evolve ... ... to a "Mini-Conference" (e.g., a Symposium) ... to a smaller, i.e., more specific, workshop • Possible Themes • See
