In my blog posts will I add special semantic / RDFa / microformat tags? well maybe I will when I better understand it -- I do type my html "raw"... so whats a few more attributes.

What I think is important for website developers / designers / admins is to make this as transparent as possible. If I create a new content type using CCK I need to be sure that if someone creates that content type that the final output has the semantic markup in it. That is several layers of complexity that "we" as a community need to think about .... will it be easy for someone like me or will it not happen...

In The Real Semantic Web Shannon Whitley hit a nail on the head .... something everyone excited about the Semantic Web and close to my heart ... drupal needs to think about how to overcome.... to quote from his post:

For example, I may write a blog post about an upcoming party: "I’m having a party at Chucky Cheese on Saturday at 10 a.m." Data can be gleaned from that post; Chucky Cheese is a location and Saturday at 10 a.m. is a date/time value. A human can easily pick out the data elements and (if they’re invited) will know where to go and when to show up. Today’s computers can’t even begin to understand that information unless you place clues around those pieces of data. Much like HTML, you would need to use codes to tell a computer, “This is the location of the party, and this is the date and time.”

Example:

    I’m having a <event>party</event> at <location geo="773838383,3838282″>Chucky Cheese</location>
    on <start-time "2008-03-29 10:00″>Saturday at 10 a.m.</start-time>"

In my party example, the encoding could result in computers having the ability to pick the information off of a web page and do things like insert the event right into your calendar, or copy the location coordinates to your GPS system so that you’ll know exactly where to drive.

The collective "drupal brain" needs to think about how this will work as much as how to build the plumbing that will make all of the "linked data" interoperate.

I so want to play with SPARQL using my data and the world!!!
