Abstract: A computer-implemented method comprises obtaining export data representing a first classification in a first database that is to be imported into a second database, the first classification including a first set of classification markings that correspond to a first classification scheme identifier of the first database and that determine access to the first database and including a first plurality of origin classifications, each original classification of the first plurality of origin classifications including a classification scheme identifier; determining that a specific original classification of the first plurality of origin classifications has a specific classification scheme identifier matching a second classification scheme identifier of the second database; importing the specific original classification into the second database as an imported classification.

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 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: storing a database change comprising a property value, the property value having an exporting site property type as defined in an exporting site ontology for an exporting site; using an ontology map to map the exporting site property type to an importing site property type defined by an importing site ontology for an importing site; transforming the property value to an intermediate property value based on the importing site property type; transforming the intermediate property value to a first round-trip value based on the exporting site property type; and determining whether to export the database change to the importing site based at least in part on a comparison between the property value and the first round-trip value.

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: Techniques for replicating changes to access control lists on investigative analysis data are disclosed. After a change is made in a database to an access control list (ACL) governing access to a secured component of a data object, an exporting nexus sends an ACL change network message to an importing nexus. The ACL change message includes information that importing nexus can use to apply the ACL change to the importing database. Applying the ACL change message includes using the information in the ACL change message to determine which change records for which secured components of the data object in the importing database the ACL change should be applied to. By doing so, user access to all change records in the importing database to which the ACL change is applied is governed by the new ACL, thereby preventing unauthorized access to the change records, including historical change records.

Abstract: A system and 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 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.
