Embodiments relate to a unified management interface and related resources for managing sets of model objects. A modeling client can host modeling logic and an application programming interface (API) to create, access, manipulate, and import/export modeling objects used in modeling applications, such as engineering, medical, financial, and other modeling platforms. The source data accepted into the modeling client can include consumer or business-level applications, whose spreadsheet, database or other content can be extracted and encapsulated in object-oriented format, such as extensible markup language (XML) format. A graphical control application can be used to manage one or more sets of modeling objects from a unified interface, to permit, for instance, the selection and configuration of the connections, activation status, security settings, and/or other attributes of model objects. The management interface can be used to control how the model objects and other resources can exchange outputs, share internal data, and otherwise operate.
