Template documentation

This template stores the Semantic MediaWiki data for one occurrence of a jam. It should never be invoked manually. Instead, use Visual novel jam statistics/maintenance to edit the jam series page, including one instance of Template:Jam and one or more instances of this template.

Each jam series is stored as a page in the Jam: namespace using Template:Jam. Using this template, each occurrence of that jam is stored as a subobject of the jam series page. The entire VN jam statistics system is based on querying data from pages in the Jam namespace, using this template and/or the Jam template.

This template should only appear on pages in the Jam: namespace, and only within instances of Template:Jam. All occurrence templates are placed within the occurrences parameter of Template:Jam.
