I wonder if we need a standard for core names. (Andreas)

OK, I hope I'm doing this right. Somehow I find the wiki thing not very intuitive and I'm too lazy to find out how it really works...

Here's what I use for my own project; I don't distinguish between stable isotopes, Mg/Ca and trace elements when it comes to metadata. Since I'm working with legacy datasets there are only a few things that I consider essential (indicated with (E)), but I think we should push to make the remaining metadata fields at least recommended:

Parameter (E)
Parameter.type (E): measured or inferred
Parameter.unit (E)
Parameter.analytical.error: based on repeat measurement of standard, 1SD
Parameter.reproducibility: based on repeat measurement of sample, 1SD
Instrument
Laboratory
Species (E): in case of foraminifera
Nshells.measured: number of shells used
Size.fraction: size fraction of foraminifera shells
Notes
Habitat.Season: from paper
Habitat.Depth: from paper. add epifaunal, infaunal for benthics
Equilibrium.offset: from paper
Calibration.eq: for inferred parameters
Calibration.uncertainty
Calibration.DOI
Publication.DOI: publication(s) where data were reported
Data.source (E): to allow tracing of legacy data, either DOI, link or ...

For trace elements cleaning method would be a good one to include.
