Abstract: In an embodiment, a computer-implemented intellectual property exchange module manages a price rules database along with many items of digital content (e.g. documents). The intellectual property exchange module maintains information (e.g., a unique identifiers) about where the digital documents reside anywhere on the World Wide Web and delivers the documents to a consumer by means of a hyperlink. In an embodiment of the present invention, a document identifier database maintains information about where a document may reside. An embodiment of the present invention implements license filtering so as to dynamically filter for pre-existing applicable licenses. For example, license filtering is used to translate the many details of a legal license into concepts that can be implemented in a digital computer.

Abstract: A method for transferring data representing a network topology from a first software environment to a second software environment is provided. The data are reformatted for this purpose, since it is assumed that the different software environments support different file formats, as is the case, for example, with customary network design programs or network simulation programs. Furthermore, the data are reorganized before or after the reformatting in such a way that a different mapping of the network topology results. Consequently, the method allows an automatic transfer of network topology data from one software environment into another, even though the two software environments use different data formats and different topology representations.
