RSCML - Really Simple Catalogue Markup Language

The Meta Feed format
Last updated by Anon on Tuesday, 08/14/2001 - 13:07

There is a need for aggregators of RSCML to exchange lists of the feeds they have discovered. This helps to promote the standard and encourages the development of more complete indexes.

This does not need as much detail as the full RSCML but many of the attributes are shared.


<?xml version="1.0" encoding="ISO-8859-1" ?> //standard XML header
<rscml version="0.1"> //defines the version level of this feed
<channel>
//A single feed. Multiple <channels> could be concatenated into one feed

<title></title>
//required. A one line name for this channel

<link></link>
//required. The URL of the owning website. Ideally the web page that describes the RSCML feed.

<url></url>
//required. The recommended URL of this RSCML feed.

<webmaster></webmaster>
//required. The email address of a contact at the owning website.

<description></description>
//optional. A short description of this channel.

<rec collection frequency></rec collection frequency>
//optional. The likely frequency of updates in seconds. Gives a guide to how often readers should check for updates.

<last modified date></last modified date>
//optional. The date in ISO standard format

<uddi id></uddi id>
//optional. A UDDI ID for this organization

<category url=></category>
//optional. A category in which to place this feed with the URL of a category standard that this is taken from. eg UNSPC

<image>
<link></link>
<width></width>
<height></height>
<alt></alt>
</image>
//optional. A link to a small image file that can be used by the reader when the RSCML data is displayed.

<rscmlversion></rscmlversion>
//optional. The RSCML version of the referenced feed.

</channel>
</rscml>


Note that all strings are assumed to be CDATA and should be character encoded.
Generally, strings should be allowed to contain html as long as this is also entity encoded so that the feed remains valid html.
