1. A computer-implemented process, comprising using a computing device to perform process actions for: providing one or more fork-join models that represent a pre-defined conflict resolution policy, defined by a cloud data type, for updating a primary revision of data shared between a plurality of computing devices connected to a networking environment; maintaining the primary revision on one or more of the computing devices acting as a primary host, said primary revision representing a local revision held by the primary host; initiating one or more forks of the primary revision to one or more of the computing devices acting as any of clients and secondary hosts to create one or more nested levels of forked revisions, each forked revision stored as a local revision by the computing devices receiving those forked revisions; performing one or more update operations on any local revision to create corresponding updated local revisions; and providing eventually consistent transactions by joining one or more updated local revisions received by any particular host into the local revision of the particular host, and applying all update operations that were performed on the received updated local revisions, in the time between the fork of the primary revision to the corresponding computing device and the join of the corresponding updated local revision, to the local revision of the particular host in accordance with the conflict-resolution policy.
