Motivation

Component based FrameworksManual coding of simple security service on various frameworks:

In this case approx.: 4000 LOC/ monthtoo much for mass deployment

Further testing on OSGiConfiguring support needed

Conclusion/ Outlooksimplification of eHome system software development needs:

component based programmingconfiguring support

regard semantic aspects

future workparametric contracts replacing function labels -> capture more semanticsglue code reduction
