Abstract: A method comprises receiving a query via a graphical user interface (GUI); running the query against a gazetteer system to obtain one or more geographical coordinates; causing a presentation in the GUI of a digital map including a set of regions corresponding to a set of geographical coordinates from the one or more geographical coordinates; receiving a selection of a region of the set of regions; causing a presentation in the GUI a geotag dialog for an object corresponding to the region, the object being of an object type in an ontology model and having a plurality of properties; receiving via the geotag dialog a selection of a property of the plurality of properties; associating a geotag with the property, the geotag including a geographical coordinate of the one or more geographical coordinates corresponding to the region, wherein the method is performed by one or more processors.

Abstract: A mapping system comprising processes for creating and displaying structured geotagged data using interactive digital geographic imagery is disclosed. In one embodiment, a mapping system comprises processes and logic for creating a geo tag for structured data. A user creates a geo tag for a property of an object by selecting a geographic location on an interactive digital map and selecting the property of the object from a dialog presented to the user in response to selecting the geographic location. In this way, the user can more quickly and easily create structured geotagged data than can be accomplished using typical approaches requiring the user to manually enter geographic coordinates to associate a geographic location with structured 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: 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 are provided for more efficient multi-row atomic, consistent, isolated and durable (ACID)-compliant transactions with snapshot isolation semantics (or just “multi-row transactions” for short). In some embodiments, the techniques are implemented in a computing system that includes a client application, a lightweight in-memory lease-based lock service, a multi-row transaction orchestrator, and an underlying database system. The transaction orchestrator implements a read protocol and a write protocol that provides support to the client application for carrying out multi-row transactions against the underlying database system irrespective of whether the database system itself supports multi-row transactions. The transaction orchestrator explicitly maintains transaction-level locks obtained from the lease-based lock service as part of the transaction protocol.

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 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.
