Hi Scott,

I am also trying to sort it out. Clearly the end-user is very reluctant to use any kind of naming scheme which means that any connection between STEP, MTConnect and QIF will have to be represented by up to three UUID's.

In principle, this is OK, but trying to manage things by UUID number is going to be tedious/difficult.

I note that the Internet made IP addresses manageable by giving its address numbers equivalent domain names, and by allowing descriptive text strings to be included in URL's.

Perhaps we need to do the same. Perhaps JSON is a solution. Perhaps every new UUID needs to be registered with every entity that is listening.

ST-UUID/MT-UUID/QP-UUID     where ST-UUID is the prototype definition, MT-UUID is the twin instance, and QP-UUID is a measurement

And it would be nice to know that ST-UUID is the definition of a distance dimension (which one?), MT-UUID is a product that has been machined (which one?), and QP-UUID is a measure of the dimension (which one?).

Martin,

In my effort to understand what was presented today I tried to imagine what the data structure would look like for a given instance. I use the Json format, it’s what understand, to map it out in my head. Just wanted to send to see if I’m on the right train of thought.

Thanks,
