Overview

  • About OHSs

  • A view on the history of OHS workshops

  • Potential new directions

  • Programme of today's workshop

    ...

  • Wrap up


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)


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: [email protected]


The New Web Site

http://www.ohswg.org/


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


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)

Statistics on the OHS Workshop Series


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.


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.)


Potential Directions 2/3

Wrap up of the Workshop

  • The Proceedings

  • Questions and Issues


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.


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!!!


Questions/Issues

  • This presentation will be available at the workshop site

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


Moving on

  • Evolve ...

    ... to a "Mini-Conference" (e.g., a Symposium)

    ... to a smaller, i.e., more specific, workshop

  • Possible Themes

    • See
