  • Access Policy. Who can view or listen to what content, where? Library staff typically develop an access policy (sometimes in consultation with legal counsel), but the policy needs to be reviewed and implemented by IT staff. An access policy may need to address student use, faculty use, source of content (library-owned or instructor-owned), recordings of an institutions's own performances, classroom use, distance education use, and textbook companion recordings. Here are some sample access policies in use (singly or in combination) at various institutions:
    • Anyone on the campus VPN can access any content.
    • Anyone on a computer in the music library can access any content.
    • Students on the roster of a class for which the instructor has requested Variations access can access any content.
    • Students on the roster of a class can only access content on the reserve list for that class.
    • Items not held by the library but belonging to faculty can only be accessed by students in a class for which those items are on reserve.
    • Music library staff can access any content.
    • Music faculty can access any content.
  • Collection Policy. What materials will be put into Variations? Will instructor-made compilation recordings or score coursepaks be digitized? Will materials for large-enrollment classes have priority? What fragile-media materials could be better-accessed via Variations? What about recordings of institutional performances?
  • Discovery. How will people find out what items are available in Variations? The Variations search window only works if extensive cataloging is done to the digitized content. Most institutions choose instead to make Variations content accessible from their OPAC and/or from reserve lists.
  • Workflow. How will digitizers put content in Variations while tracking their work?
  • Sound quality. The Quicktime streaming can handle automatic fallback from a higher bitrate to a lower-quality one if the network connection cannot support the higher-quality streaming. So some sites encode audio at two rates, 192kbps and 28kbps. Variations can handle other bitrates as well, but 192kbps seems to be a good compromise between bandwidth and sound quality.
  • Preservation Strategy. The Variations digitization process typically starts with uncompressed wav and tiff files, but it does not deliver those files. Variations is not a preservation system per se, so each institution makes a decision about whether and how to provide long-term storage the compressed master files.
