Hello all,

I had an action item to find my work from ages ago on CURIEs, and the
following is what I tracked down. Note that a few lines are commented
out, and I cannot remember why. :(

You'll see that some of this stuff relates to RDFa, but I thought I'd
leave it in, in case it's useful. (Quicker than deleting.)

Regards,

Mark
