David,

thanks for the address; I also think that entity identifiers should not be multiplied beyond necessity. Though 
different HTTP URIs always refer to different addresses, it is possbile that they have identical application 
(e.g. identification of a number with meaning "Length"). To reduce the frequency of redundancy, definitions of 
HTTP URIs could contain lists of keywords. Text search restricted to the definitions can disclose existing 
definitions about a specific topic to prevent from redefinitions. If there are nevertheless redefinitions, 
webmasters can ask web search engines for the most frequently used HTTP URI, and prefer it in their web pages. 
So we can get concentration to one name again. This is one possibility, I will contact okkam, perhaps we can 
exchange some ideas.

Best
Wolfgang
