[Nml-wg] NML Examples repository

[Jeroen van der Ham]

Hello,

The e-mail notification for commits doesn't seem to work yet, so I'm
doing a manual announcement. I've just committed a new RDF description
of the example.

- I've cleaned up the example and made it use the
urn:ogf:network:example.net: namespace
- Replaced all "connectedTo" statements with unidirectional Link objects
with source and sink

Main difference with the XML example so far (besides the size ;)) is the
way that I have described adaptations. The XML references the
SwitchingService in the adaptation relation, while in the RDF there is
just a "adapts" predicate between the two ports.
The label is associated with the upper port.

Any comments are more than welcome.

Jeroen.
