I have started FMA brotherhood recently and I want to follow its question. But then A&M have only one tag for it is fullmetal-alchemist, covering FMA manga, FMA anime and FMA brotherhood. But as most of us already know FMA anime and FMA brotherhood anime are different shows, so why not use two different tag for them? I even suggest to make three tag: one for manga, two for each anime, as FMA anime is also non canon to FMA manga but FMA brotherhood is.
Currently, we're in the process of spliting different continuities and spin-offs into separate tags discussed in this meta, with some compromises.
I would like to use the FMA series as a test pilot for our tag continuity change. If successfully implemented, there will likely be a meta of franchise tags to help users keep track of them.
What I propose is the following:
There will be a general franchise tag fma-series (the full title is too long, adding series distinctly defines it as a franchise tag, to avoid confusion with the original series in the franchise), a tag for the original 2003 anime (and movie) fullmetal-alchemist-2003(needs to be distinguishable from from just "fullmetal-alchemist" because users will tend to only use "fullmetal-alchemist" regardless of whether or not they are talking about brotherhood or the original series), for FMA:Brotherhood fma-brotherhood, which will include the manga. Synonyms will be added to better associate the two when querying "fullmetal-a..." (all three tags should appear).
There will be an explanation in the tag wiki of the franchise about what is covered in what tags and how to use them.
All FMA question will include the franchise tag and w/e respective series tag. E.g., fma-seriesfullmetal-alchemist-2003 for questions about the original series, and just fma-series for franchise specific ones applicable to either the original or Brotherhood.
For standalone series
For series with no spin-offs and only one continuity, the series tag will function like a franchise tag, until there is a need to distinguish them.
