Abstract: A facility for materializing a document is described. The facility identifies within the document a reference to a document fragment. The facility uses an identifier contained in the identified reference to retrieve document fragment contents stored separately from the document. The facility causes the retrieved document fragment contents to be displayed in context of the document.

Abstract: A facility for managing an electronic document is described. The facility receives from a user input selecting a portion of the document, as well as input designating the selected document portion as being subject to approval-gated sharing. The facility persistently stores an indication that the selected document portion is subject to approval-gated sharing.

Abstract: A facility for authoring a document is described. The facility receives first user input that identifies content to be included in the document. The identified content is in a first form. The facility also receives second user input that specifies a transformation operation to be performed on the identified content in order to transform the identified content from the first form into a second form. The facility applies the specified transformation operation to transform the identified content from the first form into the second form for display.

Abstract: A facility for providing configurable access to a document's history is described. The facility receives input specifying one or more revisions to a document. The facility causes to be stored a representation of at least a portion of the revisions. When the facility receives a request to materialize the document for a particular entity, the facility materializes the document in a manner that includes any of the represented revisions only if the entity is among an authorized class of entities.

Abstract: A facility for annotating portions of a document shown in a visual representation of the document with annotations reflecting aggregated document activities performed with respect to the portions is described. The facility specifies a visual representation of at least part of the document. For each of at least two portions of the document that are not identical and that are represented in the specified visual representation, the facility attaches to locations in the document's visual representation corresponding to the portion a visual annotation reflecting an aggregation operation against document activities performed with respect to the portion.

Abstract: A facility for performing contingent redaction of one or more portions of a document is described. The facility receives a request to materialize an identified document that identifies an entity for which the identified document is to be materialized. For a portion of the document identified by the request, the facility retrieves a criterion that must be satisfied to include the portion in a materialization of the document identified by the request. The facility evaluates the criterion for the entity identified by the request with respect to a present time. The facility causes the document identified by the request to be materialized for the entity identified by the request in a manner consistent with the result of the evaluation.

Abstract: A facility for interacting with an electronic document is described. The facility causes to be displayed a visual representation of the document, and receives input representing a painting interaction with a portion of the displayed visual representation of the document that corresponds to a portion of the document. In response to receiving the first input, the facility imposes on the corresponding portion of the document a distinguished content classification level.

Abstract: Concepts and technologies are described herein for generating scenes and tours in a spreadsheet application. In accordance with the concepts and technologies disclosed herein, a computer system executes a visualization component. Selection of an option to create a tour can be detected by the computer system. In response to detecting selection of the option, the computer system can create a tour. The computer system also can detect selection of an option to add a scene to the tour. The tour can be saved. Playback of the tour can be started in response to detecting selection of a play option. If the playback is paused, changes made to the tour and/or the scenes can be tracked by the computer system, and an updated version of the tour can be saved.

Abstract: Concepts and technologies are described herein for displaying temporal information in a spreadsheet application. In accordance with the concepts and technologies disclosed herein, spreadsheet data can be obtained at a computer system. The spreadsheet data can include data values, temporal information, and geographic information. The computer system can generate a visualization of the spreadsheet data based, at least partially, upon the data values, the temporal information, and the geographic location information. The computer system also can output the visualization.

Abstract: A facility for servicing a request for a document is described. The facility receives the request, which identifies the document and specifies a time for which the document is to be constituted. In response to receiving the request, the facility accesses information representing a number of editing actions performed on the identified document. The accessed information indicates, for each of the represented editing actions, a time at which the editing action was performed on the identified document. The facility responds to the request with a version of the identified document that reflects all of the represented editing actions whose indicated time is before the specified time, and that reflects none of the represented editing actions whose indicated time is after the specified time.

Abstract: A facility for analyzing comments attached to electronic documents is described. The facility compiles a data set reflecting comments attached to each of a plurality of electronic documents. The facility analyzes the compiled data set to generate at least one comment analysis result, and outputs the generated at least one comment analysis result.

Abstract: A facility for presenting document contents is described. The facility receives input denoting selection of one of a plurality of visualization forms. The facility renders the document contents in accordance with the visualization form whose selection is denoted by the received input, and causes the rendered document contents to be displayed.
