Termselection arguments that support non-matching #15

Open RieksJ opened 11 months ago

RieksJ commented 11 months ago

Currently, termselection can add or remove MRG entries based on the (existing) values of fields.

For example, status[draft] selects entries that have a field status: draft.

However, it would be nice to have a syntax that would be capable of selecting all entries that have a status field defined, whose value is NOT draft.

This issue calls for proposals for such a syntax (e.g. using the ! character, as in status[!draft]), deciding on it, and then modify the TEv2 specifications and implement it.

The proposed syntax using the ! character should work fine, as an alternative I'd say using the keyword not may work well. status[!draft] status[not draft]

This raises other ponderings: what would be the meaning of

status[not draft, envisaged, reviewable]?
termType[not concept, not pattern, relation]?

Would logical expressions make sense (i.e.: can we think of realistic use-cases for that)?

I would like to do this, because there is a need for it (in the digital passports projects).

However, I want to start small, implementing the following features:

[ ] Let the ! (and/or) not operator in front of a text mean that every MRG entry that does NOT have the text in the designated field, is selected;
[ ] Let the * operator mean that EVERY MRG entry that has a text defined for the field (not being the empty string) is selected. This means, e.g., that status[*] selects all entries for which a status field is defined, not being the empty string.

@Ca5e: can you comment on this?
