The linkml-map schema has a PivotOperation

PivotOperation: |

aliases: |
|
- melt/unmelt |
|
- reification/dereification |

In EAV this is the name of the 'A' variable |

In EAV this is the name of the 'V' variable |

description: In an unmelt operation, attributes (which are values in the long/melted/EAV |
