Neat. Let's look for motivating use cases. The example above: @prefix ex: <http://example.com/things/>. @suffix ex: <#it>. ex:foobar a <Baz> . could be more tersely written: @prefix ex: <http://example.com/things/foobar#>. ex:it a <Baz> . If there were multiple terms in the single namespace with the same suffix, we'd see some payoff: @prefix ex: <http://example.com/things/>. @suffix ex: <#it>. ex:hub a <BikePart> . ex:tire a <BikePart> . ex:spoke a <BikePart> . over: @prefix hub: <http://example.com/things/hub>. @suffix tire: <http://example.com/things/tire>. @suffix spoke: <http://example.com/things/spoke>. hub:it a <BikePart> . tire:it a <BikePart> . spoke:it a <BikePart> . The other benefit being that visually, ex:hub, ex:tire, ex:spoke are all grouped by authority and the names are easy to read. I have a hard time convincing myself that reading <#it> as an IRI is consistent (for instance, the base can't be resolved when you parse the suffix directive), but in pathological cases, that can be said of prefixes as well. > Best, > Richard -- -ericP
