Editing: Wiktionary is a wiki that users can edit, and its entries are written by volunteer editors.
License: The main page says content is dual-licensed under Creative Commons Attribution-ShareAlike 4.0 International and the GNU Free Documentation License.
Inclusion limits: Entries focus on words and language matters, and terms generally need evidence of sufficiently widespread use to qualify for inclusion.
