Eric KansaDoes anyone have a guidance of useful #metadata for the documentation of #XRF datasets in #archaeology and #culturalheritage domains?
@electricarchaeo If only you still studied Roman bricks. You'd probably also be a XRF metadata expert geek!
Shawn Graham@ekansa I put all my xrd and xrf stuff on figshare years ago... As it happens I've come into possession of a pxrf and I need to get certified to use it so ... Ask me in a year?
@electricarchaeo hmm... You purchased a pXRF? I wonder if this is the start of your super hero origins story.
@ekansa "do not point at face"

Now I'm curious what all the metadata is in a pdz file, which should have everything for a Bruker.

@bischrob @electricarchaeo cool! do you have an example handy?
Here's a link with a pdz and my best guess at the metadata fields. You can use read_pdz in python to access the pdzs.

James Allison@bischrob @ekansa @electricarchaeo If you open a pdz file in Bruker's (proprietary) Artax software, there is a 'parameter' tab that gives you 15 fields of metadata. It's a good start, but one obvious omission is information about the istrument itself. And the instrument I use has two collimeters in different sizes (3 or 8 mm); collimeter size should probably also be included in the metadata. If you are reporting quantitative data, you would also need to add metadata on the calibration method.
@bischrob @ekansa @electricarchaeo
For metadata on the calibration, I think minimally you would want the method (empirical versus fundamental parameters). If the calibration is empirical, important fields would be the name of the calibration, the reference samples set used to create the calibration, and the software used to create it.
