About ohss

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

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 ohswg

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

Wrap up of the Workshop

  • The Proceedings

  • Questions and Issues


The proceedings 1 2

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

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

The ohs workshop series1

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

Moving on

  • Evolve ...

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

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

  • Possible Themes

    • See
