Good question!

By deciding the want to denote yourself using a given identifier, 
relative to your profile document. Basically, the steps are as follows:

1. Open a file

2. Describe yourself using terms from your preferred vocabulary

3. Save the file

4. Publish to the Web

Fundamentally, the data transformation issues enabling what I am 
demonstrating are an implementation detail written into our tools (which 
comply with these concepts). Even if you didn't have said tools at your 
disposal, the act of describing one's self still breaks down the same 
way -- with or without a Web i.e., you describe yourself in some 
document where you identity is relative to said doc :)
