These namespaces are all being used in extant FOAF. There may be more.
They are broadly the same but with varying numbers of properties defined
each of which is in the same format. So the application needs to know
that they're equivalent. It was easier to write stupid code that just
looked for "%relationship%" and grabbed everything after the final / or
# as the description. Then strip the "Of" and upper case the first
letter and you have a textual description.
Actually the namespace definition could just not bother defining
properties. It could be a meta description: Define whatever relationship
you like in camelcase and with "Of" appended. So if someone wanted
"exWifeOf" they could just go ahead and use it.
All that is just *so* not RDF. But it does handle a useful bit of data.
