        A Collection is a group of resources. Collections have descriptive metadata, access metadata,
        and may links to works and/or collections. By default, member works and collections are an
        unordered set, but can be ordered using the ORE Proxy class.

        An Object is an intellectual entity, sometimes called a "work", "digital object", etc.
        Objects have descriptive metadata, access metadata, may contain files and other Objects as
        member "components". Each level of a work is therefore represented by an Object instance,
        and is capable of standing on its own, being linked to from Collections and other Objects.
        Member Objects can be ordered using the ORE Proxy class.

      <rdfs:comment xml:lang="en">
        An AlternateOrder is an alternate ordering of its parent's members.  It should only order the
        parent's members, and otherwise has all of the features of ordering (some members may be
        omitted from the order, members may appear more than once in the order, etc.).

        A File is a sequence of binary data and is described by some accompanying metadata.
        The metadata typically includes at least basic technical metadata (size, content type,
        modification date, etc.), but can also include properties related to preservation,
        digitization process, provenance, etc. Files MUST be contained by exactly one Object.
