No, I am telling yuou in a more or less completely un-machine-readable way (because I am slack and don't have a handy RDF scheme to use for an annotation to my page somewhere) that those URIs are stable, and that you can use the first one as an identifier for the mail message, and the others as identifiers for me, to the extent that you trust W3C to be stable and me to understand their policies accurately. cheers Chaals On Thu, 12 Apr 2001, Sean B.

Use a date stamped MID for the email (message IDs are only required to be unique for two years). As for identifying Charles, you have the three options that Sandro recently outlined. I would suggest that unless you want to re-represent Charles, you use an anonymous node:- [ :name "Charles McCathieNevile"; :worksFor "W3C"; :date "2001" ] If you want to reuse the node, then simply give it a proprietary name:- @prefix : <#> . :Charles :name "Charles McCathieNevile"; :worksFor "W3C"; :date "2001" . Where Charles could possibly be an HTTP URI if you want people to dereference it to find out more information about Charles. A good example might be a FragID to his W3C homepage. Note that the more information you include, the less persistent your data will likely be, e.g. Charles might move his homepage, but if you used a TANN it should remain persistent. Once again, through date-stamping, and being careful to recognize the scope of your data-store, you should be able to avoid any major problems. -- Kindest Regards, Sean B.
