1. A method of collaboration, comprising: enabling a user to spatially define one or more mapped locations; automatically non-programmatically collecting application data identifying a current user of an application from a mapped location of the application and automatically signing the current user on to an integration system as the current user of the integration system, wherein in response to a lack of application data in the mapped location of the application, signing a current user out of the integration system; automatically non-programmatically collecting application data from a first mapped location of a mapped source reference of a first document when the current user accesses the first document through an application used by the current user; when a second user accesses a second document through an application used by the second user while the current user is accessing the first document, automatically non-programmatically collecting application data from a second mapped location of a mapped source reference of the second document; determining whether the collected application data from the first mapped location matches the collected application data from the second mapped location; and when the first collected application data matches the second collected application data, automatically notifying at least one of the current user and second user that the at least one of the current and second users are accessing associated documents, wherein the first and the second documents are indexed by populating document properties for the first and the second documents using the collected application data.
