Abstract: A portion of a source mixed reality (MR) experience is retrieved. Then, the portion of the source MR experience is used to generate a serialized representation including a hierarchy of tagged elements. The hierarchy of tagged elements includes a plurality of MR step elements collectively defining a procedure to be performed by a viewer of an MR experience. Each MR step element has child elements that include an MR step number indicating a position of the MR step in the MR procedure and an MR step ID element indicating an identity of the MR step. The serialized representation is deserialized to generate a portion of a target MR experience to be edited in an MR development tool. The portion of the target MR experience is usable to cause each MR step in the plurality of MR steps to be graphically represented in the MR development tool.

Abstract: A facility for providing an XR device-based tool for cross-platform content creation and display is disclosed. The facility causes a definition of a mixed reality (MR) procedure to be presented by an editing MR device in a virtual application window. Input is received via the editing MR device. The facility interprets the received input as one or more editing actions performed with respect to the MR procedure definition and alters the MR procedure definition accordingly. The facility creates a device-independent representation of the MR procedure based on the altered MR procedure definition.
