For my purposes, the vast majority of conferences pretty much require a view of the conference sessions in this fashion:http://www.alt.ac.uk/altc2006/timetable/timetable.php
Perhaps there needs to be a second template available on the OCS to produce that kind of page (allowing the admins to choose between a FLAT view and a TABLED view of the conference programme.
Otherwise the organisers of a conference have to duplicate the work to achieve that document in PDF format.
In another opensource system I am looking at, this possibility exists, albeit with some technical issues, by creating a script which pulls database information, using an accompanied template, to produce LaTEX files. These latex files can then be converted through a PDFLATEX converter to produce html pages and PDF documents (Programme, Abstracts book, List of Speakers, etc.) This seems to me to be an excellent addon. At any point in time the admin runs a TEX script to generate the .TEX files, overwriting any existing .tex file in its folder. The templates are all editable, allowing considerable decision on colours etc.
That said. Any thoughts on how, for now, I might produce a PROGRAMME TABLE like the one in the URL above? I really cannot impress enough on the need for conference attendees to see, in a glance, the whole conference (if its modest enough in its design) and to print that from a web or pdf to keep with them.
