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
