RSS 1.0
Published in December of the 2000 by the members of the working party RSS-DEV. This specification supposes to adopt the specification XML 1.0 and the original compatibility with documents maintains it RDF. Of the same form the meaning of the acronyms is maintained RSS (RDF Site Sumary).
Obligatory elements
A document RSS is a document that describes a channel of information with one or various links to URL (called items and do reference to notícias). Each item is formed by a title, a link and a brief explanation of the same one.
General considerations
RSS 1.0 is compatible backwards with RSS 0.9, in the same way, is compatible with XML 1.0 and RDF.
Spoil type -- the recommendation is to define the document as "application/xml". Also it can be registered like RDF or still better, as RSS.
File extension -- is not necessary a specific extension for RSS 1.0, although is recommended. rdf or. xml.
Encoding -- RSS 1.0 utilizes UTF-8, although can also be utilized ISO-8859-1, header by defect of HTTP).
URLs -- Only the following are accepted links: http, https, ftp; mailto only is accepted in the link textinput.
Special characters -- XML is reserved various characters, if is desired to include them in the document one must substitute them for the siguients codes. "<" sustituir por "<", ">" to substitute for ">", "&" to substitute for "&"
So great of the content -- Not restrictions exist al so great although for effects of compatibility backwards is recommended not to surpass the limits of RSS 0.9.
