If not, should we have some sort of additional metadata
about the context a style is used in (consistent coding of the
publisher, place, etc.)?
Not sure what you mean above.
What I want to do is be able to easily locate all styles by a particular
publisher. If someone requests a style for a particular journal, you’d
check all styles by the same publisher as that journal & have a
reasonably good chance of finding a style that is close.
There may be a better way to have access to this information or a way to
give a canonical id for a publisher. This isn’t a specific feature
request yet–I’d rather like for people to think of ways to make it
easier to find “related” styles.
