Abstract: A method, computer program and system for consuming reusable software assets, said assets being described with elements and attributes, said assets containing at least one variable element (VPs) themselves containing at least one variant. The user executes a program on a computer by first choosing the asset to be consumed. A decision tree corresponding to the asset is traversed, each decision point corresponding to a variable element. The decision point is processed by asking the user inputs to modify the variants of the corresponding variable elements. The modified variable elements are stored. The dependency of the decision point is indicated by a dependency attribute in the variable element.

Abstract: In some embodiments the management of revisions to segments of code or artifacts is disclosed. Such management can assist a software developer in the development of software. In some embodiments, a developer can retrieve a versioned file from a repository, modify content of the versioned file to create a variant of the versioned file, compare the variant to the versioned file, and determine a difference between the versioned file and the variant. Then, the one or more attribute can be assigned to the differences and the attributes can be indexed such that the variants can be located in response to a search. In some embodiments variants can be indexed based on a variability point to which they can be matched. Other embodiments are also disclosed.

Abstract: A method, computer program and system for consuming reusable software assets, said assets being described with elements and attributes, said assets containing at least one variable element (VPs) themselves containing at least one variant. The user executes a program on a computer by first choosing the asset to be consumed. A decision tree corresponding to the asset is traversed, each decision point corresponding to a variable element. The decision point is processed by asking the user inputs to modify the variants of the corresponding variable elements. The modified variable elements are stored. The dependency of the decision point is indicated by a dependency attribute in the variable element. The program can stop at the initiative of the user or when the decision tree is completely traversed. When the decision tree has been partially traversed, the program can be restart after the last decision point processed starting from the partially modified corresponding variable element.
