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: Systems and methods for sharing information between distributed computer systems connected to one or more data networks. In particular, a replication system implements methodologies for sharing database information between computer systems where the databases use different classification schemes for information access control.

Abstract: A system and a method enable an information analyst to use a stand-alone computer-based investigation application to conduct a disconnected investigation on shared database data in a remote location where network access to a shared data repository of the system might be only periodically available, unreliable, or non-existent. In addition, the system and method enable the disconnected investigation to incrementally incorporate ongoing updates made to the shared repository of data, and to periodically publish interim or final results of the disconnected investigation to the shared data repository. A disconnected investigation can be conducted entirely at the disconnected investigation location without having any network connectivity to the shared repository of data.

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: 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.
