[MOAB-dev] h5m: GLOBAL_ID

[Nico Schlömer]

Hi everyone,

I understand that in h5m, every entity is associated with a GLOBAL_ID. This
ID is specified in the GLOBAL_ID array of the tags groups associated with,
e.g., nodes or elements.

Now, I see that that in the example [1], the GLOBAL_ID array for nodes is
```
1 2 3 ... 409
```
and for elements it's
```
0 ... 758
```
To resolve the conflicts, the connectivity dataset of elements as the
attribute `start_id = 410`, so I can just add that value to the above IDs
and have them globally unique.

What's confusing me is that coordinates dataset of nodes also has an
attribute `start_id` and it's value is `1`! So, no adding to GLOBAL_ID
array in this case, for some reason?

Cheers,
Nico
