Supported user-facing standards

[edit] RSS

RSS stands for Really Simple Syndication and is a format for simply syndicating content from one site to another.

Elgg makes extensive use of RSS and at the moment has the following functionality:

  • Each user has an RSS feed for all of their activity
  • Each tag has an RSS feed
  • There is an RSS feed for user files
  • There is an RSS feed for user blog posts
  • Each community has RSS feeds for files, blog posts, tags and the whole community
  • RSS feeds are produced when you search on a topic, to allow you to keep track of all activity which occurs in Elgg that gets tagged with a particular keyword ('eportfolios' for example)
  • RSS feeds from external blogs or services can be automatically imported into an Elgg blog

[edit] FOAF

FOAF stands for Friend Of A Friend, and is a format for representing both profile and relationship data between people.

At present you can import and export FOAF profile data, and FOAF data is provided for connections to people and communities. At the time of writing (February 2007) there don't appear to be many FOAF applications, either on the consumer or producer sides of the spectrum. We continue to support FOAF, and there may be an internal use - but probably its usefulness on the wider web is at an end. Alternatives include the slightly easier-to-support XFN.

[edit] XML-RPC

Elgg uses XML-RPC in order to allow users to post using a standard blogging client using the MetaWeblog API. Standard URLs for some popular blogging clients are included, but in general, the URL to ping with a client is [site url]_rpc/RPC2.php.
