1. A computer-implemented method, comprising: parsing a plurality of entries containing data into one or more parts, each entry associated with a metastructure containing metadata; attaching a user-provided label to a user-selected part of a selected entry selected from the plurality of entries, the label being added to the metadata for the selected entry so that the label is cross-indexed with the selected entry, cross-indexed with the user-selected part and cross-indexed with other entries containing the label; altering the data contained in the selected entry to create an updated entry; cross-indexing the updated entry with the selected entry; updating the metastructure associated with the selected entry to reflect relationship changes caused by updated entry, the updating including a time the selected entry was altered, the metastructure associated with the selected entry maintaining a list of at least one relationship change between the selected entry and at least one other entry that shows an evolution of the selected entry over a time period that includes a time period before the updating; displaying the updated entry in response to a request for the selected entry; receiving selections, via at least one displayed selector, of a time slice and a perspective to apply to the selected entry, the time slice corresponding to a period of time, the perspective being a date reference that controls a selection of labels displayed with the selected entry; consulting the metastructure associated with the selected entry to retrieve relationship changes for the selected entry during the selected time slice and perspective; and displaying a view of the selected entry governed by the time slice and perspective, the view displaying the data for the selected entry as it existed during the selected time slice and displaying labels for the selected entry based on the selected perspective.
