[ESIP-all] New ESIP Cluster proposal - request for comment

[Hannah Ake]

Hello,

I will be out of the office starting March 26th and returning April 5th. I will have limited access to email during that time, but will be checking in periodically. If you have an urgent matter that cannot wait until my return, please contact info at bco-dmo.org. 

Thanks so much for your patience.

So, I think UDUNITS, CF standard names, time, and the like could certainly be within scope. ASCII vs Unicode seems like more of an edge case. But we can figure out those types of details as the cluster moves forward.

One thing that may creep into data model structures are data representation *standards*, such as ISO representation of time, SI units of measurement, representing tilt vs earth normal, ASCII vs Unicode, and so forth.  Is the notion of standard representation within scope or out of scope when discussing these data models?

The approval process for new metadata attributes in these areas is a bit of a black box, not very transparent, and also presents a significant bottleneck for PI’s of newer remote sensing projects that are providing newer flavors of measurements that are not currently captured by both UDUNITS and the CF standard name list.
