Create standard for custom resource bundles

It should be possible for end-users, to create, share, and import custom resource bundles. This will allow us to keep Decentraleyes lean and tidy, without having to disappoint power-users. To be able to support these bundles, we will need to develop an open standard. Bundles should contain the actual resources, and essential metadata (such as resource mappings, a title, and a description).

Feel free to weigh in with suggestions, ideas, or concrete proposals.
