What should an infobox contain?
In general, data in infobox templates should be:
- Comparable. If a lot of different subjects all share a common attribute (for instance, all people have a name and a date of birth), then it is useful to be able to compare these across different pages. This also implies that where possible, material should be presented in a standard format.
- Concise. Infobox templates are "at-a-glance", and used for quickly checking facts.
- Materially relevant to the subject.
- Already cited elsewhere in the article. Infoboxes, like the introduction to the article, should primarily contain material that is expanded on and supported by citations to reliable sources elsewhere in the article. However, if necessary (e.g., because the article is currently incomplete), it is possible to include in infoboxes.
