Hi, First of all, thank you for this amazing library and for the value it adds to the community, I am working in this project: http://linuxemr.org And will do all scheduling parsing using iCal standard, for which this library is "the" way to go. (I am pretty much trying to imitate google''s cal) Please correct me where I am wrong with my thinking, and let me know how you''d do it. I am thinking of creating a rails model that matches icalendar definitions, and thinking of storing all its data into the database, not sure yet about the following: Does it makes sense to map it into a database? For display, I am thinking on a xml builder template that can receive variables such as time interval, time start, time end, day start (for week), day end (for week) and I still need a way to figure out how to assign a unique id (for the ajax staff and to populate the <div>) for each time slot, so far my thinking is that i can include a calculated timestamp as the id into xml template builder Any hint that will help me in the right direction is highly appreciated. Thank you in advance, Andres
