BACKGROUND: I am in the process of creating two data collections: one will contain an eventually long series of weekly newsletters, and the other a similarly long series of weekly podcasts. Each week the newsletter will be sent out to newsletter subscribers and the creation of a new podcast will be announced. in contrast to the newsletters whose access will be unlimited to both subscribers and non-subscribers, the podcasts will be made available only to subscribers past a not yet determined number of weeks. I have not yet decided whether to produce separate newsfeeds (RSS/RFD/ATOM) for the newsletters and podcasts or only one newsfeed for the newsletter.
QUESTION ONE: Is it possible to produce a single feed that provides access to separate folders of content?
QUESTION TWO: Typically feeds refer to content that is readily accessible each time new material is made available. How does one typically go about making accessible only the most recent addition to a folder while controlling who does and not have access to the other members of the folder.
