  A metadata schema, named Plasma-MDS, is introduced to support research data
management in plasma science. Plasma-MDS is suitable to facilitate the
publication of research data following the FAIR principles in domain-specific
repositories and with this the reuse of research data for data driven plasma
science. In accordance with common features in plasma science and technology,
the metadata schema bases on the concept to separately describe the source
generating the plasma, the medium in which the plasma is operated in, the
target the plasma is acting on, and the diagnostics used for investigation of
the process under consideration. These four basic schema elements are
supplemented by a schema element with various attributes for description of the
resources, i.e. the digital data obtained by the applied diagnostic procedures.
The metadata schema is first applied for the annotation of datasets published
in INPTDAT -- the interdisciplinary data platform for plasma technology.
