I'm going to go back to the original Q - I am assuming if you are asking about this line:


<link rel="alternate" type="application/rss+xml" title="RSS" href="http://www.site.com/rss/" />


Then you probably already know what RSS is, and possibly how to use it.

You would place that line in your page so that other applications that are searching your site for an RSS feed (RSS reader?) can locate where your feed is automatically.

If you know of a page that is using that link statement, put the URL of the page in at the validator here:
http://feeds.archive.org/validator/

(try http://www.alistapart.com/ )


The validator will be able to automatically find the RSS feed to validate it.

Where as this site:  http://builder.com.com/  which has an XML logo prominently on the front page, if put into the validator, does not have the link statement, and the validator can not find the RSS feed.

That's a lot of questions :-)

Start with a read through on this...

I'll see if I can dig up some tutorials on this under my desk somewhere...

Free Tool: Subnet Calculator

The subnet calculator helps you design networks by taking an IP address and network mask and returning information such as network, broadcast address, and host range.

One of a set of tools we're offering as a way of saying thank you for being a part of the community.

I have not seen a link done that way.  rel="altenate" I'm not sure of.  The only time I have senn alternate is for stylesheets in the form rel="altenate stylesheet".

So I don't know what browsers support that format and I would think it has to be accompanid by an XHTML doctype.

Good links from Sean deal with the RSS part, but I'm not sure if that link format is supported.

2.0 certainly needs xhtml - but I'm sure the others did as well.

This is where you should validate your documents:
http://rss.scripting.com/

There's a few listed here if you're interested as well:
http://www.cxliv.org/jayseae/2003/08/08/time_for_validation.html
There's a whole pile of feeds down the right hand site that you can test through the validator to get an idea pof what's happening.

It looks like 0.91 (netscape) had slightly different rules - it's old news though so don't worry about it

The RSS spec from Harvards seems to cover most of the details.
