    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.

    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.
