Concern-oriented source code projections

The quality of the source code structure is a matter of the point of view, one programmer might consider one structure the best, the other not. A concrete structure can help in certain situations with the program understanding. Therefore we propose using dynamic structuring that allows assigning multiple structures to one source code to aid program comprehension. Concern-oriented source code projections facilitate this dynamic structuring expressed by custom metadata and provide multiple views of the source code that reflect logical structures provided by the dynamic structuring. This way in a specific situation a programmer can get a structure (by a view) that meets his/her current needs the best.
