Possible Improvements:

  • for long lists, break them up into pages so they don't take minutes to load
  • bookmarks are not dynamically based on how the user arrived at the page.


  • show ncs:status if available
    • property of resource metadata (ex. 2200/20090904155332111T)
    • property of collection metadata (ex. 2200/20061002125001945T) NOTE: collection metadata is metadata provider 2200/20080317171403522T (NSDL Collection Records)
NOTE: This would approximately double the time to display the list of metadata providers and the list of metadata. Currently, both of these object types get all their information from a single datastream. Adding the display of ncs:status would require getting properties from the object xml, which is currently not accessed to construct the lists.
  • add ability to limit by ncs:status


  • show oai:visibility if available
    • property of metadata provider (ex. 2200/20090904131228646T)
    • property of metadata (ex. 2200/20090904155332111T)
NOTE: This would approximately double the time to display the list of metadata providers and the list of metadata. Currently, both of these object types get all their information from a single datastream.
