For both the FSF and OSI we have a few set of related tags:
- There are few questions that are focused on the organisations, and that will probably always be the case. Those that do will probably be well served by using either free-software/open-source and the history tag.
- We have several questions that concern approval by the organisations on the basis of the definitions. The tags would end up being redundant in these circumstances.
- Simpler and fewer tags are better in general.
I think we should make free-software and open-source be the core tags with the others as synonyms. These tags will need careful tag wikis which explain that they are for questions which concern the organisations/definitions and they should not be used for general FLOSS-related questions. (I think a general FLOSS tag would be too general and should not be used.) We will need to diligently watch these tags to make sure that they don't get used for general questions.
