[RFC] XML_RfdCalendar, XML_GeoInfo, XML_FOAF, File_iCalendar

Hey, Long time, no action on my part ;) I've just had to skip about 500 (had over 1500 to catch up on) e-mails so if I'm doing anything wrong, feel free to yell! Basically, I'm working on stuff at the moment which makes use of all these technologies. RdfCalendar - This is an RDF based implementation of the icalendar spec. GeoInfo - An RDF based markup for defining lat/long and some other stuffs FOAF - An RDF based markup for describing yourself and linking yourself with friends. icalendar - A standard for writing calendars, as used by Mozilla Calendar, MS apps (not sure which but its their standard it appears) and the OSX Calendar app too (it seems) Currently, I don't have any working code, I'm just curious as to whether or not anyone would be interested in seeing me develop this code with PEAR in mind. What I have in mind: XML_RdfCalendar I plan for the user to be able to do the following: Create a complete calendar from scratch, doing something like: $event[1] =& XML_RdfCalendar::new_event('foo'); $event[1]->set_start_time($start_time); $event[1]->set_end_time($end_time); $event[1]->set_description('bar baz'); and also tasks too, in a similar fashion, you just pass the array of events and an array of tasks to the XML_RdfCalendar::render() or some such and it'll output the RdfCalendar... I would also like for the package to parse icalendar files themselves and output RdfCalendar. File_iCalendar This is going to be a counterpart to XML_RdfCalendar, I would like to take RdfCalendar files and generate ical files, and also ical files from scratch (obviously) XML_GeoInfo I still need to explore this technology some more, I've yet to see enough depth to justify a package *just* to output the XML... However, I have had thoughts about allowing the output of world maps with geographic points marked on them... I would be nice to also narrow this down to smaller maps, but the user would need to say from what lat/long it runs from and to.... XML_FOAF I'm surprised this package hasn't been created already... Anyways, XML_FOAF will serve to generate a full FOAF file... I would also like to write some sort of digging tool... i.e. read a FOAF file, then go read friends files, then go read friends files upto a given depth... and then output in a variety of formats which I've yet to think up :) I've been exploring ways to tie FOAF together with GeoInfo and RdfCalendar too, so I'll look to see if I can tie all three packages together whilst also leaving them open for tying together with *any* XML based technology, we have to remember that XML allows for namespaces and we need our code to accomadate the users want for them. Anyhow, this is all pre-liminary RFC... thoughts? - Davey
