"corona" and "coronasdk" both refer to Corona SDK most of the time. Sometimes tag refers to something else I didn't figure out what is. It seems a rarity, though.

Actually, , and have a tag excerpt, and a tag wiki that contain a description of (or a reference to) the Corona SDK. This means the purpose of both the tags is the same.

There are 164 questions that use both the tags. The tags should be merged.

  • Thanks :) Can I get a explanation of the difference between tag merge and tag synonym then? I mean, why use synonym?

  • A tag merge involves all the questions, past and future; a tag synonym involves only future questions. If corona is made a synonym of coronasdk, future questions using corona will see that tag replaced with coronasdk, but the tag is still shown in old questions. If corona is merged with coronasdk, all the questions that use corona will see it replaced with coronasdk.

Finally, after nearly an year has become a synonym of .

Though the count is different for both tags, I think it'll be fixed after next cache cycle runs (or something; since it's always the caching).

  • Nope, that's not how tag synonyms work. There are currently 590 questions tagged with coronasdk, and they will stay that way until they get retagged to the master tag or a moderator merges the two tags. ;)
