A unique data label is affixed to each tracked asset and a unique data label for each location in the enterprise, both real and virtual locations. Location history data of the asset is related to other asset data in a relational data base. Assets typically include system components down to the least repairable/replaceable unit (LRU). The data label, in the preferred embodiment of the invention, is a code label using a code that ensures each label is unique to the asset or location to which it is attached. Here the word location is an inclusive term. It includes the geographical location and the identity of the building in which the asset is housed. Location also includes the identity of the system of which a component is a part and, if relevant, location within the system. It includes also any real or virtual location of interest for subsequent analysis and is ultimately defined by the nature of the system being tracked.People assigned to install, upgrade, maintain, and do other work on the system are identified and this identifying data is entered into the data base along with each activity performed on the system and its components. Preferably, in response to a scanned asset label, a menu of allowable activities is presented so that the person assigned to do a task associated with the asset can easily make entries into the data base of the code assigned to the task performed. With asset data, asset location, and task record (including the person performing the task), entered into the relational data base, it is relatively easy to track the components of complex systems in a large enterprise over time and build complex relational records.

A hierarchical structure is established among a plurality of RFID tags, such that ID numbers can be read only from RFID tags which belong to a particular layer. RFID tag can control whether permission should be given to read its ID number therefrom to protect the ID number. Data held in the RFID tag can be read from the outside. RFID tag comprises a memory circuit having a function of holding data, and a logic circuit having a function of processing a control command received from outside. Memory circuit stores an own ID nmber for identifying the RFID tag itself, and a parent ID number for identifying a second RFID tag. When RFID tag receives an ID number read command which contains first data as a parameter from outside, the logic circuit outputs the own ID number to outside only when the first data matches the parent ID number.

A method and system for controlling access to data via a data-centric security model. A business data classification scheme is defined as a hierarchy that includes data types aligned with business operations. A data element is labeled with a data label. The data label includes multiple attributes associated with a data-centric security model. A first attribute is a data type of the data element. A second attribute includes security requirements. Data control rules are automatically generated for an enforcement of the security requirements. The enforcement grants or denies to a user an access to the data element via a predefined action. The enforcement is based on a predefined association among the predefined action, a predefined role that includes the user, the data type and, optionally, a purpose for performing the predefined action.

A spreadsheet system stores objects and formulas in the cells of the spreadsheet, along with metadata tags. Each cell may contain multiple objects (such as a group of photos). Drag-and-drop user actions automatically change tags associated with the moved objects based on a formula stored in the target cell if a forcing semantics mode is active, or automatically change a formula stored in the target cell if a non-forcing semantics mode is active. A formula in a cell selects a set of objects and may include set operators such as union, intersection, and minus. The formula may also filter sets to select a subset based on specified tag attributes of objects. The display of the spreadsheet adaptively selects a subset of objects to render in a cell and appropriately scales photos for optimal viewing.
