Architecture that facilitates generation of an event report that is an aggregation of public and private data related to a specific task. Information about the event is automatically compiled, including the recipients, URLs, shares, attachments, and documents, as well as location maps and social relationships. The report can be a one-page document that summarizes topics of a meeting or event, the attendees, how the attendees relate, their motivations, and what the attendees may be looking for from the meeting. The report can be formatted to structure event information in a certain way such as according to a company organizational chart, such that an attendee that is higher up on the org chart will be presented on the report higher than someone who is lower on the org chart. Moreover, attendees can be grouped according to functions, or social groupings or project groups, for example.
