                     The best architecture for a repository depends on the purpose of the    Building the Requirements List
                 repository and its anticipated use. Because the platform determines how
                 information is added, processed, stored, searched, and used, it has an
                 enormous impact on the user experience as well as on all staff functions
                 relating to the repository. For this reason, understanding the opportunities
                 and challenges conceptually and the technically divergent approaches that
                 exist is essential to making a good choice.




                 Questions to Ask before Choosing
                 an Architecture

                 Planners must have a solid understanding of what fundamental needs the
                 repository serves and who will interact with it before identifying a repository
                 platform. Virtually all repositories support a certain set of basic functions,
                 such as adding, processing, managing, storing, and disseminating resources.
                 Because the way in which these functions are implemented determines what
                 can be done and how, it is critical to translate how people expect to interact
                 with the repository into a set of platform requirements.
                     For example, if materials need to be protected, access controls are
                 essential. If your library lacks the expertise or technical resources to install
                 the repository, you’ll need a system that can be hosted or maintained by a
                 vendor. If data that requires protection for privacy, intellectual property, or
                 other reasons will be stored, data controls are required. If users need to be
                 able to manipulate large numbers of objects in the system, it must support
                 bulk operations in a workflow they would find acceptable. If support for
                 provenance or genealogy is required, appropriate metadata and navigation
                 support are necessary.
