Abstract: Techniques for cross-ACL multi-master replication are provided. The techniques allow a replication site in a multi-master replication system implementing an asynchronous replication protocol and an access control policy to appropriately apply received data change updates to data maintained at the site even where a data change update is missing information because of the implemented access control policy.

Abstract: A system and method providing cross-ontology multi-master replication is described. In a first embodiment a method for cross-ontology multi-master replication comprising the steps of: obtaining, at an importing site, an exporting site ontology and a set of one or more database changes; wherein the exporting site ontology defines a set of one or more data types; and after mapping the exporting site ontology to an importing site ontology, incorporating the set of one or more database changes into a database including mapping each of one or more data types of the set of data types to a data type defined by the importing site ontology using an ontology map.

Abstract: Systems and methods are provided for storing a first data object comprising a first set of immutable components, the first data object being associated with a corresponding second data object stored by a remote replication system. A difference is determined between the first set of immutable components of the first data object and a second set of immutable components of the corresponding second data object. A subset of immutable components is identified from the first set of immutable components based on the difference. The subset of immutable components from the first set of immutable components is provided to the remote replication system over a communication network.

Abstract: A computer-based method and system for sharing and deconflicting data changes amongst a plurality of replication sites. In a particular embodiment, data changes at sites to data objects are tracked by each site on a per-data object basis using per-data object version vectors. In another particular embodiment, data changes at sites to links connecting two data objects are tracked by each site on a per-link set basis using per-link set version vectors. In another particular embodiment, per-object version vectors are used to detect a conflict resulting from concurrent changes at two or more sites in which one of the concurrent changes includes an object resolution change.
