The Semantic Web isn't just about putting data on the web. It
is about making links, so that a person or machine can explore the web
of data.  With linked data, when you have some of it, you can
find other, related, data.

Like the web of hypertext, the web of data is constructed with
documents on the web. However,  unlike the web of hypertext,
 where links are relationships anchors in
hypertext documents written in HTML, for data they links 
between arbitrary things described by RDF,.  The URIs identify
any kind of object or  concept.   But for HTML or
RDF, the same expectations apply to make the web grow:

1. 
   

   Use URIs as names for things

   
   
   
2. 
   

   Use HTTP URIs so that people can look up those names.

   
   
   
3. 
   

   When someone looks up a URI, provide useful information.

   
   
   
4. 
   

   Include links to other URIs. so that they can discover
   more things.

Think of a input URI that has some RDF syntax content, or some
microformat that
Raptor
can understand via GRDDL.

Think of the output format you want from this list:

• HTML - use html
• JSON - use json
• RSS 1.0 - use rss
• N-Triples - use ntriples
• RDF/XML - use rdf (this is also the default)
• Turtle - use turtle (n3 also works)

If the format you are thinking of is not on this list, sorry but
Triplr won't work for you yet :(

Form a URI in your head that is
http://triplr.org/output format/input URI


Give that to a web browser or other application.

Done!

What follows is what I consider to be best practice for my personal sites and a guide for those who wish to do the same. Months ago I dropped the www. prefix from my domain in part because I think it’s redundant and also because I wanted to experiment with how Google treated valid HTTP redirect codes. The experiment has been a great success. Google seems to fully respect 301 Permanent Redirects and the change has taken my previously split PageRank has been combined and now I am at 7. There are other factors that have contributed to this, of course, and people still continue to link to my site and posts with a www. (or worse) in front of it, but overall it just feels so much cleaner to have one URI for one resource, all the time. I’m sure that’s the wrong way to say that, but the feeling is there nonetheless.

Now for the meat. What’s a good way to do this? Let’s look at our goals:

• No links should break.
• Visitors should be redirected using a permanent redirect, HTTP code 301, meaning that the address bar should update and intelligent user agents may change a stored URI
• It should be transparent to the user.
• It should also work for mistyped “sub domains” such as ww. or wwww.
