Where should I store information/metadata used for configuration on every document library in a SPWeb, and how can I let site administrators change this data (as settings, GUI)?
My use case:
When a word document is added to a document library it will be converted to PDF which is copied to a another given document library.
For example any word document added to "MyArticles" will get a corresponding PDF in "MyPDFs".
The setting I need to store is an URL or some pointer stating that "MyArticles" corresponds with "MyPDFs".
