Flexibility in LCIA metrics for completeness field

[bl-young]

In v2.2, new metadata are added to assess data quality like "Completeness" that are specific to LCIA metrics:

Are this list of metrics defined anywhere? Is it possible to change them?

There is currently no water use metric for example.

Currently, it is the list as defined in the ILCD format. There it is defined as a fixed list / enumeration (adding values would break compatibility). In the openLCA data model, these values are just stored as strings, so the list could be extended here. Best would be, to get these updates into the official ILCD format... but this is maybe not easily possible.
