Give yourself a URI
Do you have a URI for yourself? If you are reading this blog and you have the ability to publish stuff on the web, then you can make a FOAF page, and you can give yourself a URI.
A lot of people have published data about themselves without using a URI for themselves. This means I can't refer to them in other data. So please take a minute to give yourself a URI. If you have a FOAF page, you may just have to add rdf:about="" and voila you have a URI http://example.com/Alan/foaf.rdf#ABC. (I suggest you use your initials for the last bit). Check it works in the Tabulator.
The URI will start with "http" (so I can look it up using HTTP) and it will have # in it, so the URI of your foaf file is different from the URI for you.
The AWWW says that everything of importance deserves a URI. Go ahead and give yourself a URI. You deserve it!
