RSS 0.90 is the earliest known version of RSS released to the public, and was replaced by Netscape's RSS 0.91 (Revision 1). It was created by Netscape to be a metadata format providing a summary of a website. (And not only a syndication format, as it is today.)
RSS 0.90 is an RDF-based format.
When RSS 0.90 was created, the RSS initialization stood for Rich Site Summary and not Really Simple Syndication. (See RSS - What is in a Name for more info on RSS's naming history.)
NOTE: RSS 0.90 has been deprecated. Producers of RSS SHOULD NOT be creating RSS 0.90 feeds, and SHOULD instead use a newer non-deprecated RSS format. (See the RSS Versions List for a list of non-deprecated RSS formats.) Consumers of RSS SHOULD still be able to accept RSS 0.90 feeds though.
RSS 0.90 looked something like this:

Note that here, RSS is being used to list sections of the web site. Rather than for syndication.
