~

Properties:

defaultFlowProperty Ref[FlowProperty] Some LCA data formats do not have the concept of flow properties or quantities. This field provides a default link to a flow property for units that are contained in this group.
units List[Unit] The units of the unit group.

~

Properties from CategorizedEntity:

category Ref[Category] The category of the entity.
tags List[string] A list of optional tags. A tag is just a string which should not contain commas (and other special characters).
library string If this entity is part of a library, this field contains the identifier of that library. The identifier is typically just the combination of the library name and version.

~

Properties from RootEntity:

name string The name of the entity.
description string The description of the entity.
version string A version number in MAJOR.MINOR.PATCH format where the MINOR and PATCH fields are optional and the fields may have leading zeros (so 01.00.00 is the same as 1.0.0 or 1).
lastChange dateTime The timestamp when the entity was changed the last time.
