I'm sending you my first try of mapping owl topology desc into nml. Please, treat this as a start point for further discussion in order to get the final proposal for the NSI team. Hi Roman,
Hi Freek,
I have three main comments for now.
1. You use the nml "next" relation to signify a network connections. The "next" relation is already in use to describe something else: the order in XML lists (as such it is merely a syntactic construct, instead of an actual connection/relation between network elements). This was proposed in Salt Lake City last year, and agreed upon by a small margin.
I replaced that with nml-nsi:type="connectedTo" (suggested by Jeroen). See my last update. But even if we wanted to use "next" I wouldn't see the problem in using it for network connections and lists (in fact, network connections are the lists of ports or links).
2. You seem to define network ports and create relations between them to define a network topology. The NML method is instead to define the links, and create relations between them to define a network topology. You can either connect two links using a port, or connect them directly together (which is slightly shorter to describe circuits through a network).
I wanted to be as close as possible to the example that Jeroen sent. I believe that NML should be flexible and allow creating relations between ports or links. I see (this is my vision) NML as a set of components that you can use to build various complex topology structures according to the needs raised by users (in this case NSI).
3. As Jeroen mentioned, I would refer to vCard for defining contacts, and XML (or OWL) schemas are great in combining multiple schemas in one document.
Done. See my last update. Roman
