Abstract: A method and a system are described that involve generating a graphical tree hierarchy of a data structure and its accompanying metadata. In one embodiment, the method includes building a graphical tree hierarchy with a plurality of levels, wherein the graphical tree hierarchy includes at least a root node, a plurality of non-leaf nodes, and a plurality of leaf nodes. Further, the method includes aggregating at least a portion of the plurality of non-leaf nodes at a level of the graphical tree hierarchy, if a subset of the plurality of non-leaf nodes residing at the level exceeds a maximum number of nodes per the level. The method also includes scaling down the plurality of leaf nodes, if the plurality of levels of the graphical tree hierarchy exceeds a maximum number of levels.

Abstract: A method of processing licensing keys includes specifying a program defining a set of executable instructions where different subsets of executable instructions define different products. A set of licensing keys are constructed. Each licensing key has a fixed number of symbols, where each symbol includes multiple bits. At least one symbol is configured to be mapped to at least two fields and at least one field is configured to be mapped to at least two symbols. Each field specifies a feature of a product defined by a subset of executable instructions of the program. The program and a first license key are distributed to a first end user, while the program and a second license key are distributed to a second end user. The first license key is processed to define features of a first product. The second license key is processed to define features of a second product.
