@cameronneylon I don't think there is an "accepted standard". Probably the most generic you could use is Dublin Core.
There is a XMP dc namespace https://www.exiftool.org/TagNames/XMP.html#dc which could be used to add metadata to the image directly.

I wouldn't trust any processing steps to preserve image metadata though. I think most softwares just strip an image clean before using it.

@quachpas dc certainly makes sense. And if I did it super properly if I end up in XML there's things like PROV as well Some brief experimentation showed that XMP metadata seems to be preserved for (otherwise untouched) images that have been inserted into Google Slides and OO Impress presentations and then exported back out (Google doesn't make it easy but I found a way) Obviously not to be relied on but a potentially useful backup in some cases.
