1. A method, comprising:
Identifying, for a first portable device at a first location in a three-dimensional (3D) physical environment, a first sparse map, the first portable device connected to a remote computing system for accessing sharable world data of the 3D physical environment that comprises a physical object, wherein
the plurality electronic devices include the plurality of portable devices having respective sparse maps installed thereupon;
Identifying, for a second portable device at a second location in the 3D physical environment, a second sparse map, the second portable device connected to the remote computing system for accessing the sharable world data; and
performing, by the second portable device, content persistence for a virtual content relative to the physical object at least by using a merged map, wherein the merged map is determined at least by merging a version of the first sparse map and a version of the second sparse map based at least in part upon one or more persistence coordinate frames (PCFs).
