RSS is a family of web feed formats. The initials "RSS" are variously used to refer to the following standards:
* Really Simple Syndication (RSS 2.0)
* Rich Site Summary (RSS 0.91, RSS 1.0)(I prefer this one)
* RDF Site Summary (RSS 0.9 and 1.0)
A web feed is a data format used for serving users frequently updated content(Such as our UNP Forum threads or news contents etc.). Content distributors syndicate a web feed, thereby allowing users to subscribe to it. Making a collection of web feeds accessible in one spot is known as aggregation.
