Re: [wildfly-dev] Analyse the management model

If version was an distinguishing property of a resource node then the relationship between versions becomes another edge. Or version is a node and the relationship between versions are edges. Either way those relationships aren’t really clear though. Version 1.7 and 2.0 may both be descendants of version 1.6 but 2.0 is not directly related to 1.7. And we don’t store the kind of version relationship data that would allow that to be worked out automatically. Anyway, this stuff is a bit of a tangent, although a worthy one. On the main point, cool! Good job. Just last week I was messing around looking for cases where we had attributes that were both required and had a default (which is wrong since the ‘required’ makes the default pointless). This would have saved me some time and probably still will as I’m sure I’ll have to redo the search to make sure I got it right. > On Feb 6, 2017, at 7:33 AM, Harald Pehl <hpehl(a)redhat.com&gt; wrote: > > Good point.
