Abstract: Systems and methods for joint document signing are described. According to one aspect, a method for joint document signing includes establishing a live communication session including a plurality of users. In some cases, the plurality of users correspond to a set of signers of a document. The method further includes initiating a signing process during the live communication session, receiving a signature for the document from each of the plurality of users during the live communication session based on the signing process, and generating a signed document including the signature from each of the plurality of users.

Abstract: Systems and methods for collaborative document signing are described. According to one aspects, a method for collaborative document signing includes initiating a live communication session including a user, identifying a source document for an agreement using an agreement signing interface of the live communication session, assigning the user as a signer of the agreement using the agreement signing interface, and generating the agreement. In some cases, the agreement includes the source document. The method further includes obtaining a signature for the agreement from the user and generating a signed agreement including the signature.

Abstract: Methods and apparatus provide for an abstract model interpreter that defines an abstract model to represent an interactive video. The abstract model is defined independent of any export format. An interface for the abstract model is created to concurrently manage interpreting the abstract model according to a plurality of different export formats. For example, the abstract model interpreter can map a feature of the interactive video, which is described in the abstract model, to a corresponding feature supported by an export format. The interface is thereby utilized to interpret the abstract model to create a formatted interactive video, which is a version of the abstract model compliant with an export format from the plurality of different export formats. The interface further provides an edit capability that allows a user to modify how the feature of the interactive video is to be supported by any of the different export formats.

Abstract: A system traverses a directed cyclic graph to discover a relationship between a first object and a second object, and creates an alias. The alias represents the second object. The system replaces the relationship between the first object and the second object with the created alias, and creates a reference from the first object to the alias.

Abstract: Novel techniques and tools for authoring multimedia compositions are presented. The novel techniques and tools allow an author of a multimedia composition to create a multimedia composition by dragging assets from a first window containing a project's unused assets and placing the assets into a structural relationship in a second window. The author may also remove assets from the structural relationship in the second window and return the assets to the first window of unused assets. The novel techniques and tools allow an author of a multimedia composition to better keep track of the assets to be used in the multimedia composition.

Abstract: Methods and apparatus for arranging and aligning graphical objects are disclosed. The selection of a first graphical object in a graphical user interface is received, and it is determined if the first graphical object is located at a substantially minimal distance in a reference plane from a related second graphical object on the graphical user interface. If the graphical objects are not located at a substantially minimal distance from each other in the reference plane, the graphical objects are graphically arranged to substantially minimize the distance in the reference plane between them.
