Hey Roman,
Hi Aaron,
Overall, it looks good. A few questions on the schema.
1. It'd be good if StartTime/EndTime/Duration were specified explicitly instead of being anyElement* (e.g. an xsd:string that contains a unix timestamp)
I did this way to have it very generic. The UML diagram from nml-base.pdf does not define too much details. For Lifetime it has only "sequence of (start,end)".
I agree that we could do with a better specification of those dates and the duration. Iirc there are some standard types in XML that can handle that.
- Relatedly, is there any reason to have both Duration and EndTime instead of just one or the other?
I think there are some scenarios where you'd use one or the other, or perhaps even both where you ask for a link that you will use for some duration, but it has to be before endTime.
2. Apparently, in the US, zip codes can have a different form than just an integer. 5 digits, a hyphen and 4 digits (e.g. 20037-8001): http://en.wikipedia.org/wiki/ZIP_code#ZIP.2B4
I took it from https://svn.internet2.edu/svn/nmwg/trunk/nmwg/schema/rnc/topo/nmtopo_base.rn.... This can be updated.
Zipcode would be a good place to have just an xsd:string. Who knows what crazy scheme some countries come up with :) Jeroen.
