Here are a couple of suggestions of release date formats that could be used:
-1 Copyright Date: Found on the cover/title screen, should be replaced when better info is found.
-2 Announced Date: Future release dates that have officially been announced by Publisher (Source to be provided), when the game is out, the users would be prompted to verify that the game is actually release on that date
-3 Official Date: From Publisher's website, Magazine, Software shop website or other reliable source. Needs to be documented.
-4 Outside Source Date: Taken from another gaming website or wikipedia, temporary and is tagged as such and needs to be verified with better sources.
If Oregami has a missing info/most wanted feature, cases 1 and 4 would show up in the search. Actually, I think any item in the database could be tagged as temporary if the provided source is not accurate enough, or in the case of covers with creases, low-quality, etc.
