Abstract
A historian system enables the creation, storage, and retrieval of extended metadata properties. A tag metadata database module of the historian system stores tag metadata received over a network connection in a tag metadata database and retrieves tag metadata in response to requests received over the network and from within the historian system. An extended property database module creates extended properties associated with a tag metadata instance in response to requests, stores the created extended properties, and retrieves the stored extended properties in response to requests. The extended property search index module indexes extended properties as they are created, searches the indexed extended properties in response to requests, and provides the indexes of extended properties to enable location of the extended properties in the extended property database.
