An open science field is a structured corpus of public knowledge designed to be readable, citable and extendable by humans and machines. It is not a journal, a book or a database. It is an operative architecture: a system of named concepts, stable identifiers, public documents, machine-readable metadata, repository distribution and consistent citation formats. An open science field is built to be found, parsed and reused. It does not require institutional validation to exist. It requires structural coherence and public availability. Socioplastics is an open science field. Start here: https://antolloveras.blogspot.com/p/socioplastics-project-index.html
