Examples

Hi, Richard suggested that we make a diagram of the complete examples. I've just done that (and found some errors through that). It's not completely cleaned up yet, but it should give a pretty good impression of what we currently have in the examples. Would it be useful to also include this in the doc? Jeroen.

Lifetime
by Jeroen van der Ham 13 Mar '13

13 Mar '13

Hi, Time is always a very difficult problem. We have tried very hard to define this properly in the schema. There was one small gap that we missed: when a Network Object did not have a Lifetime *and* no new Topology object with a version attribute was published, or a new one is and does not contain a description of that Network Object. I've expanded the description in the schema to this, can you please check if this covers all cases and whether you agree with it? If a Network Object has no associated \emph{Lifetime} objects, or the start or end attribute of a Lifetime object is missing, the default lifetime may be assumed to start on or before the time specified in the version attribute of the most specific Topology object that contains this Network Object. The end of that assumed lifetime is indefinite, until a Topology object with a higher version number is published. This new description can define a new Lifetime for the object, or the Topology. If the new description does not contain the Network Object, the end time is assumed to have passed. Jeroen.

hasService / hasInboundPort
by Jeroen van der Ham 13 Mar '13

13 Mar '13

Hi, For most of the NML model we have made it so that there is only one relation defined between two objects. However, Richard spotted a situation where we do have two: - A Port can have a "hasService" relation to a SwitchingService - A SwitchingService can have a "hasInboundPort" relation to a Port Perhaps it would make sense to suggest a preference that one of them must be there and that the other is optional. The second relation is slightly more informative, so that is probably better. Jeroen.

encoding for Switching Service
by Jeroen van der Ham 13 Mar '13

13 Mar '13

Hi, Richard has performed a thorough review of our document, and an interesting question came up: Why does a Switching Service not have an encoding attribute? We have an encoding attribute for Ports and Links, including Links created by a Switching Service. So why not also include it in the Switching Service itself? I thought there was an issue on the tracker on this, but I can't find anything. Do we see any problem with this? Jeroen.
