Outline

Problem

  • Lots of data resources in NASA, elsewhere
  • Not available as data as services
  • if it is a service, e.g. openDaP, may need rich clients, hard coded, loose coupling not easy
  • Even if reusable service is available it cannot be found.
  • The Users Dilemma (direct problem)
    • There are no data for what the user needs
    • If there are needed data, the user can not find them
    • If the user can find them, she can not access them
    • If the user can access then, she does not know how good they are
    • If he knows how good they are, she can not merge them with other data.
  • Providers Dilemma (indirect problem)
    • There are no users for the data
    • If there are users, the provider can not find them
    • If she can find the users, she does not know how to deliver the data
    • If she can deliver them, she does not know how to make it more valuable
    • If the she can make it more valuable...

Solution

  • Service Orientation, while accepted has not been widely adapted for serving NASA products
  • SOA allows the creation of loosely coupled, agile, data systems
  • SOA -> requires ability to Publish, Find, Bind (Register, Discover, Access)
  • While, binding to data through standard data access protocols, publishing and finding requires metadata system


  • Metadata system for publishing and finding content has to be jointly developed between data providers and users.
  • Generic catalog systems - metadata collection of not only what provider has done but also tracking what users need
  • Communication along the value chain, in both direction;
  • Metadata the glue and the message
  • Market approach; many providers; many users; may products
