In conf.researchr.org, the model of the CMS is designed to reflect the hierarchy of actual conferences, with support for simple conferences having a single call for papers, and more complex federations of conferences with subconferences, workshops and multiple tracks per conference.
Taking a conference as starting point:
a conference can have multiple sub-conferences (like workshops, symposia, etc), or can be a sub-conference itself
a conference can have zero or more conference committees (e.g., organizing, steering, program committee)
a conference can have a front page with free text items, a photo carousel, event carousels and a sidebar with news items, supporters, widgets and upcoming important dates (aggregated from its tracks)
a conference can have one or more venues, and attending information items
a conference has a program, with automatically generated tabular and timeline views of the tracks, sessions and events with support for filtering, a personal program, and calendar feed to be imported into one’s digital agenda.
a conference can have multiple tracks
a track can have zero or more call for contributions, important dates and committees
a track can have zero or more session slots defining the time and place of the session(s)
- each session slot can be assigned events (talks/welcome/keynote/you_name_it)
- session slots are set up at the conference-level where session slots get assigned to the tracks
a track will have events with its own rubric like accepted papers/artifacts/...
a track has its own page showing the call for contributions, important dates, its program, accepted papers, committee(s), and other free text items.
