Overview

This is basically used just by APOs. Arguably “editable” is the wrong name.

Constant Summary collapse

CREATIVE_COMMONS_USE_LICENSES =

these hashes map short (“machine”) license codes to their corresponding URIs and human readable titles. they also allow for deprecated entries (via optional :deprecation_warning). clients that use these maps are advised to only display undeprecated entries, except where a deprecated entry is already in use by an object. e.g., an APO that already specifies “by_sa” for its default license code could continue displaying that in a list of license options for editing, preferably with the deprecation warning. but other deprecated entries would be omitted in such a selectbox. TODO: seems like Editable is not the most semantically appropriate place for these mappings? though they’re used by methods that live in Editable. TODO: need some way to do versioning. for instance, what happens when a new version of an existing license comes out, since it will presumably use the same license code, but a different title and URI?
