RSS 1.0

We propose a new RSS 1.0 module: ``mod_enclosures''. This module will use the following namespace definition:

xmlns:enc1="http://crocodile.org/ns/rss/1.0/enclosures"

It uses RDF vocabulary formally defined by RDF schema[4] included in appenix B.

To specify item enclosures new ``enc1:enclosures'' property of ``item'' node is added, which points to ``enc1:Enclosure'' or ``enc1:Enclosures'' node with same semantics as in RSS 2.0, but expressed in accordance with RDF/XML syntax.

In the table below you can find correspondence between RSS 2.0 attributes and RDF properties:

Enclosure Type	RSS 2.0 Attribute	RSS 1.0 RDF Property
Simple, Composite	enc:Content-Id	rdf:about
Simple, Composite	enc:rel	enc1:rel
Simple, Composite	enc:description	enc1:description
Simple	enc:url	enc1:url
Simple	enc:type	enc1:type
Simple	enc:transport	enc1:transport
Simple	enc:location	enc1:location
Simple	enc:length	enc1:length
Simple	enc:quality	enc1:quality
Composite	kind	see below

Composite enclosures also have the property ``enc1:children'' pointing to containers with sub-enclosures.

The RSS 2.0 ``kind'' attribute is expressed via specialized container types pointed by ``enc1:children'' property. The following table shows correspondence between ``enc:kind'' attribute values and RDF containers:

RSS 2.0 ``kind''	RSS 1.0 RDFS Class
parallel	enc1:Parallel
mixed	rdf:Seq
alternative	rdf:Alt
user-defined	user-defined subclass of rdfs:Container
