Abstract: Systems and methods for managing physical location data and representation data in a health data dictionary. Clinical data is represented in a health data dictionary using a vocabulary that includes concepts and representations. Each concept is a unique item or idea and each concept can be associated with multiple representations. The default representations are difficult to use because most legacy systems are already accustomed to other terms or identifiers. The present invention allows the representations in the health data dictionary to be changed, altered, or modified according to the desires, of the legacy systems. The representation to be changed is identified by the legacy system and changed in accordance with instructions received from the legacy systems. The instructions may be to update, change, add, delete or otherwise modify a representation. The location manager is used to modify physical location data including representations, contexts, and concepts.
