There *IS* such a thing as `URI'. It is a standard internet term.

That is exactly correct.

I was thinking purely in terms of connection strings. Currently you might be connecting to your database with an OLEDB connection string with your VB application, and with yet another different connection string from your Perl app, et cetera. It would be most advantageous if there were a single uniform connection string for all applications.

This would be Simply Wrong when it came to tuples. A very Bad Idea indeed.

It would make things easier.

So just ignore her.

I must again everyone I'm just stepping out on an implementation limb which is rather off-topic here, but the benefit above I consider self-evident.
