**Draft for a tag creation/deletion criteria**

A tag must fulfill all of the below requirements or it may get renamed or deleted:

1. A tag must be named appropriately, considering [Tag naming guidelines](https://electrical.codidact.com/posts/289204).
2. A tag must be on-topic, meaning it has to be related to Electrical Engineering. 
3. A tag must be unambiguous in the context of Electrical Engineering. It should not mean two very different things at once.
4. A tag must add at least _some_ meaningful information regarding what the question is about.
5. A tag should not be too localized/specialized, but about some well-known term in Electrical Engineering. If it is unlikely that other posts will ever use the tag, it is too localized.

Tags that do not fulfill the criteria may be deleted or renamed by trusted users. A trusted user in this case means someone with [full edit privileges](https://electrical.codidact.com/abilities/edit_posts) <- click the link to tell if you have them or not. DO NOT start mass-editing tags if you do not have this privilege or you will create lots of needless review work for the moderators.

If you wish to change multiple tags without having the mentioned privilege, or if you are uncertain what to do with a tag, please raise a question on meta.

Regarding 2), note that home appliances, consumer electronics or end use applications are not on-topic terms here. Area of application might be relevant however (consumer, industrial, med-tech etc).

As an exception to the on-topic rule, there may be specialized tags like `identification`, `design-review` and similar which are used to categorize a question - tags that might make a decent community category candidate.

Regarding 3), in case a term does have several different meanings and all meanings are on-topic, then the most common/jangon use of the term takes precedence. For example `PID` will be assumed to be about a Proportional–Integral–Derivative controller and not about Process Identifier in a (RT)OS - this is not ambiguous in the context of Electrical Engineering (but quite ambiguous in the context of Software Engineering).
