What is PSS?

PSS is a Web content syndication format based on its sister standard RSS.

PSS is an acronym for Portable and Simple Syndication. RSS stands for Really Simply Syndication and RDF Site Summary.

PSS is a dialect of XML and is based on RSS 2.0. All documents containing PSS must conform to the XML 1.0 specification, as published on the World Wide Web Consortium (W3C) website.

RSS 2.0 does not have the ability to include its elements in other XML formats through a namespace. PSS allows RSS 2.0 elements to exist as vocabularies in other XML documents. PSS is not an XML file format.

Sample file

Following is a sample PSS application called mypssapplication that uses the RSS vocabulary. The mypssapplication and items elements are not part of PSS, rather they are a sample application that uses PSS.

<?xml version="1.0" encoding="iso-8859-1"?>
<mypssapplication
xmlns:pss="http://tempuri.com">
<items>
<pss:item>
<pss:description>
This and that happened today for some reason.
</pss:description>
</pss:item>
<pss:item>
<pss:description>
Nothing happened today of interest.
</pss:description>
</pss:item>
</items>
</mypssapplication>

PSS Namespace

PSS must be included in an XML namespace and it may also contain other XML vocabularies.

PSS includes all the XML constructs normally available in RSS 2.0.

Restrictions

PSS may not be used as an XML file format. It can only be used as a vocabulary in an XML application. This is to prevent use of PSS as an alternative standard XML file format to RSS.

About this document

This document was created in response to David Winer's article introducing the concept. This implementation of the standard diviates from Dave Winer's concept in that PSS may include other XML namespace, but specifically cannot be used as a XML file format, rather it can only be used to include the RSS vocabulary in other XML documents.
