Append-or-update metadata/measurement_face.csv by key
Source: R/registry_measurement_face.R
register_measurement_face.Rdface_kind in structure | composition | scale | organism | standsin | none (D2-D3). A standsin row's face_of names the key whose face it
borrows and stands_in_note is the chip's short text; a row that is not
standsin never carries face_of (no borrowed ids on a key that has its
own concept, D3).
Details
short_label is the key's authored short title, the name a page head shows
beside its face (issue #30 D13); the full label from variable.csv keeps
the method notes. It may be empty (none authored yet). When set it is
non-blank, at most 48 characters, does not end in punctuation and is not
used by another key (ignoring case), counting the keys already in the file.
A row breaking any of these is refused.
