When I posted about Semacode yesterday, I had a vague feeling something was missing and bugged me rest of the day until I realized it while in the ZZ land.  It's that a Semacode maps to a URL which is a silly thing to do in the post-Google era.  Websites, particularly small websites likely to be pointed to by Semacode, tend to disappear over time and it's mostly read-only, meaning only those who own the website or are members of the website can add information to it.

Semacode should be just be a string (it could be a set of keywords or even just numbers) unique enough to be used as a reliable coordinate in the online search space so that looking it up at a search engine will return only the links directly and deliberately mapped to the coordinate.  This way people can add information about the object at the coordinate without restrictions.  If it happens to be a restaurant, they can even post a bad review on their own blogs and it will still show up on cellphones after Semacode is scanned.

The Big Idea here is that you don't really need a URL if you have good search engines.  For wiki-fans, it's like turning the entire web into a wiki of sort by using search services like Google to weave a wiki page out of pages across the Net.

Think different people.  It's all right if it has been done before as long as it hasn't been done by you.
