Abstract: A digital engineering ecosystem may comprise a plurality of digital engineering software tools, a plurality of connectors corresponding to the digital engineering software tools, and project data integration software that may execute on, and be hosted by, a computing system. Users may access the digital engineering software tools to generate design data for a project. The project data integration software may generate and store project data that may be used to track links between design data generated by the software tools.

Abstract: A method and data structures for obtaining, distributing, managing, and utilizing information, including online content and user biographical information, in an online networking system are presented. Profile data pointers that point to profile data structures and item data pointers that point to item data structures are employed to access users' views and media content in a manner that allows for viral copying of content throughout the system yet permits the system and content owners to maintain control over the content. Users' biographical information is developed based in part on users' behavior in the networking system, and is collected and aggregated in the respective data structures to support targeted advertising based on the data, and protection of users' personally identifying information.
