Discovery metadata describes a given dataset or collection. Data being published through a wis2box requires discovery metadata (describing it) to be created, maintained and published to the wis2box catalogue API.
wis2box supports managing discovery metadata using the WMO Core Metadata Profile (WCMP2) standard.
WCMP2 is currently in development as part of WMO activities.
Creating a discovery metadata record in wis2box is as easy as completing a YAML configuration file. wis2box leverages the pygeometa project’s metadata control file (MCF) format. Below is an example MCF file.

There are no conventions to the MCF filename. The filename does not get used/exposed or published. It is up to the user to determine the best filename, keeping in mind your wis2box system may manage and publish numerous datasets (and MCF files) over time.
At this point, you have created discovery metadata for your given dataset(s).
