There are various kinds of [sports officiating technology](https://en.wikipedia.org/wiki/Category:Sports_officiating_technology). 
Several sports use [instant replay](https://en.wikipedia.org/wiki/Instant_replay), this includes [video goal judge](https://en.wikipedia.org/wiki/Video_goal_judge) in ice-hockey or [Hawk-Eye](https://en.wikipedia.org/wiki/Hawk-Eye) in tennis. 
In football there is [goal-line technology](https://en.wikipedia.org/wiki/Goal-line_technology) and more recently [video assistant referee](https://en.wikipedia.org/wiki/Video_assistant_referee). And probably many other similar tools.

Occasionally there are some questions about these topics. Which tags should be (typically) used for such questions?

* Is combination of [officiating](https://sports.stackexchange.com/questions/tagged/officiating "show questions tagged 'officiating'") and [technology](https://sports.stackexchange.com/questions/tagged/technology "show questions tagged 'technology'") a reasonable choice?
* Should a new separate tag for this topic be created? (A tag encompassing various types of officiating technology.)
* Are some of these topics important enough to have a separate tag? For example, should there be a separate tag for video technology in soccer, or maybe more general for user of replays in various sports?

Unless I missed something the only existing tag related to one of these topics is [hawkeye](https://sports.stackexchange.com/questions/tagged/hawkeye "show questions tagged 'hawkeye'"), at the moment with [a single question](https://sports.stackexchange.com/questions/17662/could-hawkeye-tell-us-the-probability-of-runs-and-wickets-from-a-given-ball). Perhaps together with the above questions we could discuss at the same time whether or not Hawk-Eye is important enough to have a separate tag. (And if the consensus is that we should keep this tag, then there are a few other questions about this topic and the tag should be added also to those questions.)
