An experimental field I'm working on to try to help Catholic parishes and Archdioceses be able to store and share in a common format the many sacramental times for liturgies.
For example, many parish websites have a listing like:
Mass Times
- Sunday
- 5:00 p.m. (Vigil)
- 8:00 a.m.
- 9:30 a.m.
- 11:00 a.m.
- 5:00 p.m.
- Monday
- 8:00 a.m.
- etc...
Reconciliation Times
- Saturday
- 4:30 p.m. - 5:00 p.m.
Adoration Times
- First Thursday
- 8:00 a.m. - 10:00 p.m.
... and it would be awesome if there were a structured, sensible way to display, store, collect, and update this data. Especially if it were in a format that could be shared across systems (Wordpress, Drupal, Joomla, proprietary) using JSON, XML, etc.
See the discussion on Open Source Catholic for more info: http://www.opensourcecatholic.com/forum/topics/346
I've also thought of abstracting this information into a more generic 'time_field' module for Drupal, but I think for parishes, having a specific module would be a little better.
