Overview and constraints of EUDAT Instrument metadata elements#
The EUDAT Instrument metadata schema is based on the outcome of the Research Data Alliance (RDA) working group Persistent Identification of Instruments WG (PIDINST WG).
The following table lists the metadata elements as it was endorsed by the Version 1.0 of the PIDINST schema.
