Developing Complementary Frameworks

DDF and the underlying OSGi technology can serve as a robust infrastructure for developing frameworks that complement the DDF Catalog.

Recommendations for Framework Development

1. Provide extensibility similar to that of the DDF Catalog
   1. Provide a stable API with interfaces and simple implementations.  Reference http://www.ibm.com/developerworks/websphere/techjournal/1007_charters/1007_charters.html
2. Make use of the DDF Catalog wherever possible to store, search, and transform information
3. Utilize OSGi standards wherever possible
   1. ConfigurationAdmin
   2. MetaType
4. Utilize the sub-frameworks available in DDF
   1. Karaf
   2. CXF
   3. PAX Web and Jetty
