Formatplugin? If so, let's discuss in the scifio/scifio channel. Or if you are looking to write data to an existing but "customized" format such as TIFF, could you please describe what you are trying to do in more detail?
--Global Metadata--is added by some scary machinery in the imagej-legacy project. Here. In my tests, it happened when I opened an image with File > Import > Image... (i.e. via SCIFIO), but was not populated when opening with File > Open or File > Import > Bio-Formats... If you glance at that code link, the reason is pretty clear. Although I did not check what calls that method. Certainly this code is messy and (as the TODO there also says) needs to be restructured / moved at some point.
BioFormatsFormatpopulates the global and image metadata according to what Bio-Formats reports. I do not have a dataset handy at the moment to verify that theory though.
-- Global Metadata --section generated by that dubious SCIFIO-related code—there are other ways to go. But I'm gonna sleep now. @Fotaku, if you want more information or guidance, I suggest you post on https://forum.image.sc/
