open source
Let an agent explain open source, relay definitions, licences, governance, business models and debates from OSI, FSF and software engineering sources with positions attributed, flag instance aliases, and distinguish open source from free software as a philosophy, freeware, source-available licences, public domain and open standards.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain open source, relay definitions, licences, governance, business models and debates from OSI, FSF and software engineering sources with positions attributed, flag instance aliases, and distinguish open source from free software as a philosophy, freeware, source-available licences, public domain and open standards.
A model of development and distribution in which source code or designs are made available under licences that let anyone use, study, modify and share them, defined for software by the Open Source Initiative s Open Source Definition of 1998, related to but philosophically distinct from the free software movement founded by Richard Stallman, and extended to hardware, data and designs; the registry aliases name open-source typefaces and font families such as Latin Modern, cm-super and Nimbus Roman No. 9 L, which are instances, and open-source cars, vehicle designs shared openly. Licences range from permissive, such as MIT and Apache, to copyleft, such as the GPL, and compliance matters for organisations.
What it is for: Collaborative, openly licensed development.
It can be explain definitions and licences; relay governance and business models; present debates with attribution; flag instance aliases.
Distinguishing features
Access to source
Permission to modify and share
Community governance
Licence obligations
What it looks like
Not a physical object; seen in public repositories, licence files and community projects.
Physical character
Open Source Definition: 1998 year - OSI
GNU Project announced: 1983 year - Richard Stallman
GPL version 3: 2007 year
How it is recognised
Openly licensed development model
Open-source Unicode typeface, open-source typeface, open-source car, cm-super, Latin Modern, Nimbus Roman No. 9 L
Free software stresses user freedom; freeware is free of charge only; source-available licences restrict use; public domain has no copyright; open standards are specifications
