System Attribute Definitions

Has anyone ever seen (or attempted to produce) a list of definitions for each of the many attributes which we can see in the system data? I am only talking about those which are visible in the Portal.

I have long wished that GE had 'Alt Text' for each of the headers, to explain what they are.

To be more specific, for each of the following, and the rest, I would like to see the following meta data - A simple definition to help users, units used (e.g. Volts, Amps), which system they relate to (battery or inverter), where they are measured, what takes the measurement (internal sensor or from an EM115).

Time (of what? GE server, local equipment, something else?)
Status (of what? What does each value mean?)
VPV1
VPV2
IPV1
IPV2
PPV1
PPV2
PAC

( I have just downloaded some historic data via the download button, which gives slightly more user-friendly headers in the Excel file, but my question still stands)

Thanks very much hoggy, that is certainly a very good start. Now if they could just add that to the Portal as Alt Text then users might have some vague idea of what they are looking at.

Based on a quick comparison, it is not complete and it contains some errors, but it is better than nothing.
