bnd is the Swiss army knife of OSGi, it is used for creating and working with OSGi bundles. Its primary goal is take the pain out of developing bundles. With OSGi you are forced to provide additional metadata in the JAR's manifest to verify the consistency of your "class path". This metadata must be closely aligned with the class files in the bundle and the policies that a company has about versioning. Maintaining this metdata is an error prone chore because many aspects are redundant.
FeatureMapper is a tool approach to combine Software Product Line Engineering (SPLE) and Model-Driven Software Development.
It supports mapping features from feature models to solution artefacts expressed in EMF/Ecore-based languages (such as UML2 or your home-made domain-specific language), provides various visualisations of these mappings, allows for mapping-based transformation of solution models, and provides an extensible interface to utilise different transformation techniques.
In addition to its own feature metamodel, it also supports feature models and variant models of pure::variants, an industrial-strength tool for variant management.
FeatureMapper is under development at the Software Technology Group of Technische Universität Dresden, partly in the context of the BMBF-funded feasiPLe research project.
