Dear workshop participant,

The following has now been done:

* The existing fragments of the hyperguide can be accessed on
       http://www.ida.liu.se/hg-lac/
  It is intended that it shall later be accessed as
       http://vir.liu.se/hg-lac/
  but this apparently takes a few more days

* The web-page material that you saw during our meeting has now
  been split into two parts. The hyperguide part is accessed as
  above. The other parts (bibliography, information about
  conferences, etc) has been structured for a proposed
  "European Colloquium on Spatial and Temporal Reasoning",
  and the present structure can be accessed as
       http://www.ida.liu.se/brs/

* Lars has implemented the virtual addressing scheme and tested
  it as far as possible here, and if you access the hyperguide
  as described above you are running through it. (In order to
  run it without the script, you invoke instead
       http://www.ida.liu.se/ext/hg-lac/        )
  This means that crosslinks within the hyperguide can be written
  as we discussed during the meeting, for example as
       /logics/modal/
  and that they then go through the virtual linkage script.

It would be nice if some of you could try it soon, so that we
get additional experience with it. In order to only establish
*incoming* links from the overall hyperguide to some sections
that you write, you just need to send a message to Lars 
(larka@ida.liu.se) and tell him which hyperguide address
(for example /logics/modal/) you want to have mapped to
your machine, and where to map it to. In order to also have
*outgoing* links from your pages to pages at other hyperguide
sites, you must of course install Lars's script on your
server also.

More news:

* The hg-lac structure has further been reorganized so that there
  is first an overview page, and then a substructure for "table
  of contents". This is in line with what was said at our meeting
  about fully exploiting the possibility of "hyper" structures.
  The overview page contains a number of (intended) "entries", that
  is, starting points for marked trails through the material
  that is only listed for overview in the table of contents.

* There is various materials in the structure of "table of
  contents", but notice that it is all very preliminary.
  However,

* The table of symbols has been updated in line with what we decided
  at the meeting

* The section "latex" contains a number of macros files. In
  particular there is a file for formula-supporting macros.
  These files have been written so that they are correct html files
  (with .html extension), for viewing purposes, but they can also be 
  loaded into Latex. (Have played tricks with the comment facility 
  of Latex). Documentation will be added, but they are fairly
  self-explanatory.

* The present message has been included in the first substructure
  of "authoring information". I plan to do similarly with
  forthcoming messages whenever appropriate. Thus you don't have
  to save this message, as long as you make a note of the
  hyperguide's URL.

All comments welcome, including if something doesn't work.
Best regards

Erik

PS  I suggest we keep this structure and information "within the
    family" for the time being - it is useful to be able to put
    draft texts on the web without them being read by people
    outside the group who do not know the context. However I
    have not put any access protection on these structures - do
    we need that?
