This comes from a discussion between myself and @vlorentz . To summarize my position: I would like to be able to tell downstream users "the keys we use in our metadata are (a subset of) the codemeta ones". AFAICT that means that they should be able to look them up here: https://codemeta.github.io/terms/ . As such, we should not use keys like schema:author, but simply author; similarly we should not use codemeta:issueTracker but simply issueTracker.
