Mixed reality data collaboration

A method, comprising:

• receiving a plurality of data subtypes from a first display device, each of the data subtypes having a keyframe location and a current version;
• updating a data structure to include the current versions of the data subtypes at the keyframe location;
• receiving a neighborhood request including the keyframe location from a second display device;
• in response to the neighborhood request and based on the keyframe location, providing to the second display device an identifier for each of the plurality of data subtypes and a current version indicator for each of the plurality of data subtypes;
• receiving a data request from the second display device for two or more of the plurality of data subtypes;
• prioritizing the two or more data subtypes based on a priority hierarchy;
• and
• based on the prioritization, providing current versions of the two or more data subtypes to the second display device.

A method, comprising:

• receiving a plurality of data subtypes from a first head-mounted display device, each of the data subtypes having a keyframe location and a current version;
• updating a data structure to include the current versions of the data subtypes at the keyframe location;
• receiving a neighborhood request including the keyframe location from a second head-mounted display device;
• in response to the neighborhood request and based on the keyframe location, providing to the second display head-mounted device an identifier for each of the plurality of data subtypes and a current version indicator for each of the plurality of data subtypes;
• receiving a data request from the second head-mounted display device for two or more of the plurality of data subtypes, the data request including an identifier for each of the two or more data subtypes and a non-current version indicator for each of the two or more data subtypes;
• comparing the non-current version indicators to the current version indicators for the corresponding data subtypes;
• based on the comparison, selecting the current versions of the two or more data subtypes for provision to the second head-mounted display device;
• prioritizing the two or more data subtypes based on a priority hierarchy;
• and
• based on the prioritization, providing the current versions of the two or more data subtypes to the second head-mounted display device.
