That reassures me greatly. {grin} I would not have been able to agree with the first meaning, but I can easily agree with the second. I wanted to clarify your intent.
It's not at all clear to me that managing provenance in the global web is going to be possible without some of those "fairly
technical mechanisms" (e.g. named graphs or ), but there's a lot to be gained from simpler measures. One reason some of those more complicated measures become attractive is that they can fulfill the need for a standard way to discuss an URI as an identifier directly and not as a pointer to something identified, so that one can make assertions about it as an identifier without making assertions about the thing it identifies. This is subtle and can cause confusion, as we are seeing on this list in the last few days.
