Here is some work that my colleague in the NIST Library did in comparing the existing metadata schemas. I’m sorry that I cannot make the meeting tomorrow (and I still owe a use case!).
Here’s a draft version. The cells are colored to visually group fields with similar types of information (though I haven’t found a great way to group them beyond this). GEOFON and ICOS are not listed in the spreadsheet because they do not make specific recommendations for fields in their use cases.
The general consensus between these case studies is that there should be a persistent ID and a name attached to an instrument; beyond that there are widely different ideas about what metadata should be collected. I would say you can generally group the types of information requested in the following way (this isn’t an exhaustive list): Instrument (PID, Name, Manufacturer, Model Nos., dates of use, device type and category, description), Ownership (Name, Country, Dates of ownership, Organization PID), External references (Funding, related instruments, publications) and Miscellany (Output, characteristics, events, capabilities, observable properties).
