INFORMATIONS REGARDING FEEDS [RSS & ATOM]
Thalabathi
This time i am coming with a very interesting topic...
Everybody will be aware of that term RSS Feed and ATOM feed.
Let me proceed the post..............
A feed is a regularly updated summary of web content, along with links
to full versions of that content. When you subscribe to a given
website's feed by using a feed reader, you'll receive a summary of new
content from that website. Important: you must use a feed reader in
order to subscribe to website feeds. When you click on an RSS or Atom
feed link, your browser may display a page of unformatted
gobbledygook.
What are RSS and Atom?
RSS and Atom are the two feed formats. Most feed readers support both
formats. Right now, Google News supports Atom 0.3 and RSS 2.0.
Atom defines a feed format for representing and a protocol for editing
Web resources such as Weblogs, online journals, Wikis, and similar
content. The feed format enables syndication; that is, provision of a
channel of information by representing multiple resources in a single
document. The editing protocol enables agents to interact with
resources by nominating a way of using existing Web standards in a
pattern.
Atom consists of:
===============
A conceptual model of a resource
A concrete syntax for this model
A syndication and archiving format (the Atom Feed Format) using this
syntax
An editing protocol using this syntax
The format must be able to represent:
===========================
a resource that is a Weblog entry or article (e.g., it has an author,
date, identifier, and content)
a feed or channel of entries, with or without enclosed content
a complete archive of all entries in a feed
existing well-formed XML (especially XHTML) content
additional information in an user-extensible manner
The editing protocol must enable:
========================
creating, editing, and deleting feed entries
multiple authors for a feed
multiple subjects or categories in a feed
user authentication
adding, editing, and deleting users
setting and getting user preferences
creating, getting and setting related resources such as comments,
templates, etc.
The working group will use experience gained with RSS (variably used
as a name by itself and as an acronym for "RDF Site Summary", "Rich
Site Summary", or "Really Simple Syndication") as the basis for a
standards-track document specifying the model, syntax, and feed
format. The feed format and HTTP will be used as the basis of work on
a standards-track document specifying the editing protocol. If other
submissions are made to the working group under terms accepted by the
IETF, the working group may consider them as alternatives, based upon
their merits.
The Working Group will also take steps to ensure interoperability,
by:
==================================================
unambiguously identifying required elements in formats
clearly nominating conformance levels for different types of software
providing clear extensibility mechanisms and constraints upon them
holding at least one interoperability event
describing how one migrates from the various RSS versions to the Atom
syndication feed format
The Working Group's primary focus will be on delivering an
interoperable format and corresponding protocol; it is expected that
all but the most basic, generic metadata and functions will be
accommodated through extensions, rather than in the core documents.
