What we want to do
We want a feed parser that
- pulls latest feed info from feeds.mozilla.com for front page
- pulls latest feed info from news.rdf (for now) for front page
- optionally: creates mash ups of multiple feeds on sub-pages (e.g. Our causes > Education)
How to do it
Mozilla.org has a lot of visitors, so we probably want to cache feed items for some time to a) be nice to the feed provider and b) get better performance.
We probably want a database-based cache over a file-based cache, because it gives faster results.
TTL of the cached items can be relatively high (higher on the sub-pages than on the front page), because we offer the feeds to open up an additional window into the community and not to be a direct, always-up-to-date information resource.
- Use a cron-job to generate static html with the news items
- Pull in the items from a db-based cache, refresh the cache occasionally
There are several different options (subject to evaluation).
Write a parser from scratch
- + maybe better performance
- + would hopefully be exactly what we want
- - more development time
- - not as well tested as other solutions
- New BSD license
- very modular and flexible
- PHP5 only (read: makes use of new OOP features, which is good)
- well maintained, active development
- DB abstraction layer, cache handling
- some known issues, API a bit counter-intuitive in places
- probably not as heavily tested as other solutions (because relatively new)
- generally long turnaround time (bug filed to fix released)
- LGPL license
- No maintainer
- PHP license
- No active development (last release 06)
- BSD license
- CURL extension required (need to check with reed, if it is enabled)
- Caching out of the box (flat file only right now, but could be overloaded with own DB-class)
- Meshing of multiple feeds out of the box
- Problems with some feeds, but workarounds exist
- Nice API
- Goodies such as feed auto-discovery (feels a lot like Firefox ;)
- Performance seems to be good with caching, but no idea, if it scales up nicely.
- GPL license
- No active development (last release 05)
PHP Universal Feed Parser
- GPL license
- seems to be a one-man effort
- uses OOP methodology
