Abstract
A data store including a file location attribute is described. In an embodiment, the location attribute for a data element, such as a file or database record, is stored with the bytes of data and records the geographic location of the data element. Writing to this attribute is limited to a single trusted entity, such as an operating system, to ensure that the location data can be trusted and when a data element is moved or replicated, the attribute is updated to reflect the new location of the data element. This location data is made available to users and applications by a metadata service which tracks the locations of data elements and responds to requests from users. Access control policies can been defined in terms of location and stored at the metadata service and the metadata service can then enforce these policies when responding to requests.
