With the addition of directional information and gesture based input in a location based services environment, a variety of service(s) can be provided on top of user identification or interaction with specific object(s) of interest. For instance, a device can interact with various endpoints of a direction-based location service and any of the content or other information exchanged between clients and services can be synchronized for efficient exchange of information and efficient utilization of network bandwidth and resources. For example, change input is received by a device that alters, deletes or augments dynamically updateable information associated with a point of interest and the changes resulting from the change input are synchronized from the mobile device to a location based network service. Optionally, the synchronization can be according to a knowledge exchange to identify what should be synchronized prior to transmitting the updates.
