1. A system comprising: one or more data repositories storing an object model, the object model comprising object model elements that include typed objects, properties of the typed objects, and relationships between the typed objects; one or more memories storing a dynamic ontology, the dynamic ontology comprising ontology elements that define semantics of the object model, the semantics including object types, property types, and relationship types; a data import component configured to import data from one or more data sources into the object model; a definition component configured to generate or modify the dynamic ontology, identify one or more schema comprising schema elements that define one or more structures according to which the one or more data sources conform, and generate a schema map that defines how the schema elements map to the ontology elements; wherein the data import component is configured to generate the object model based on the one or more data sources and the schema map; and a graphical interface component configured to cause display of a graphical interface that depicts an arrangement of a plurality of the ontology elements, the arrangement depicting at least two or more of the object types interconnected by one or more of the relationship types, the arrangement including controls for receiving inputs that define and/or modify the schema map with respect to the depicted ontology elements; wherein the definition component is configured to generate the schema map, at least in part, based upon the inputs received via the controls.
