I looked through the Data Model for Lexemes.

Began playing around and looking at some of the existing data.  Then I wondered about word origins.

Example:

"Neighborhood Electric Vehicle" is a phrase first coined in the 1970's.

The earliest specific reference for this phrase is in the 1978 California Penal Code which could be pointed to as a reference.

Is there are use case for Etymology with Lexemes ?

Specifically, not just the origin of the word pointing to a previous word...through use of the existing P5191 derived from property, but when a new phrase is actually introduced to the world, typically because of a Fad, Technology, etc.

How would the year "1978" and the reference work "California Penal Code" be utilized for the earliest known date of usage for a phrase ?
