I definitely believe that additional clarity can be reached under Crown copyright as well. It ties back into open data initiatives as well. If you look at licence terms that are offered by the government under open data licences, the aim is to make these things available without restriction. That isn't completely harmonized across different levels of government. Even within different datasets, different information made available by government under Crown copyright, additional clarity there definitely would be most helpful.
