A system and method for saving metadata information related to firmware / software updates in a SIM card is disclosed. An electronic device with an update agent may employ an update package reference storage area in a SIM card to save metadata information related to a downloaded update package. The update agent may access the stored metadata information during power up or reboot in order to access and / or process the downloaded update package. The SIM card, or in various embodiments of the present invention, a smart card, a removable memory card, or a removable memory module, may be employed by the electronic device to save information about downloaded files that are stored in a file system in the electronic device. Such information may subsequently be accessed by the update agent when the file system is not available. This may occur, for example, during power-up or reboot, when the update package needs to be accessed to perform a firmware / software update.

The invention provides a metadata management method based on DBMS and a metadata server.

The invention analyzes time and space consumption needed by performing typical metadata operation, manages the flexibility of metadata, verifies that the invention can reduce time and space consumption needed by managing metadata in the mass storage system, and improves the flexibility of managing the metadata.

The invention discloses a virtual storage image version management method and system for a virtual machine. The method comprises the following steps of storing metadata and interval block data, wherein the metadata includes a mapping relationship of a physical block number and a logic interval block number of a VSI, a VSI version number, an associated next VSI version number in the time sequence, a version ID, a current version counter, VSI latest version data and VSI historical version data; receiving an operation request on a virtual disk; carrying the VSI version number and the operation type in the operation request; determining the physical block number of the VSI version number; and performing data operation. By dividing a block into interval blocks, the memory overhead can be saved in the version management process.

A method and a computer-readable storage medium are also described.

The present disclosure describes a system for saving metadata on files and using attribute data files inside a computing system to enhance the ability to provide user interfaces based on actions associated with non-executable attachments like text and document files from untrusted emails, to block execution of potentially harmful executable object downloads and files based on geographic location, and to a create a prompt for users to decide whether to continue execution of potentially harmful executable object downloads and files. The system also records user behavior on reactions to suspicious applications and documents by transmitting a set of attribute data in an attribute data file corresponding to suspicious applications or documents to a server. The system interrupts execution of actions related to untrusted phishing emails in order to give users a choice on whether to proceed with actions.

A system and related techniques expose color printing resources to applications, utilities, operating system and other resources, to automatically detect output capabilities as well as to permit integrated print functions which preserve metadata and other context within the printing workflow. According to embodiments of the invention in one regard, a set of applications may invoke or access a print subsystem to transmit one or more image files to a laser, inkjet, dye sublimation or other printer or other output device. According to embodiments of the invention, the print subsystem may interface to a color management engine and / or a non-color image management engine to automatically negotiate a set of enhanced or optimized print parameters, such as gamma correction, white balance correction, media selection or other options or parameters, for instance for color printing on photographic paper. Because those print or other output capabilities may be automatically detected or discovered, those enhanced settings may in many cases be generated transparently, without user intervention. In addition, metadata surrounding the image file including for instance file size, date and time information, editing status, printing status and other parameters may be preserved and made available to print drivers and other levels of resources in the printing chain, in both directions so that context may be consistently preserved and applications may enjoy extensive or complete control over the image printing process.

A computer system, comprising a plurality of computers; and a management computer, wherein a plurality of data stores which store data obtained from a data source and having differing attributes, wherein the management computer has a request allocation unit and holds metadata management information. The request allocation unit is configured to: refer to the metadata management information to select a candidate data store based on analysis results of the data obtaining request including the time attribute of the requested data; determine whether the requested data can be obtained from the candidate data store; determine a data store to which to issue a request for obtaining the requested data; and issue the request to the determined data store.

The invention discloses a method for generating a memu for a multi-technology platform and a device thereof. The method comprises the steps of: obtaining and memorizing metadata description information; defining the memu and memu metadata contained in the memu according to the metadata description information, and memorizing the memu and the memu metadata contained therein according to the mode of a first data structure; generating the memu metadata contained in the memu, and building and memorizing a service data table corresponding to the service according to an element object in the memu metadata; and generating a memu interface and service processing data corresponding to an object platform according to the element object of the first data structure and memu data in the service date table. By using the invention, the same memu can simultaneously support C / S and B / S application under different develop technologies, thereby preventing from repeatedly designing the memu interface, reducing the realization cost, and being capable of dynamically modifying without repeated manual modification after the memu interface is modified.

The invention discloses a method for storing metadata, which includes: when the solid-state hard disk is converted from a power-off state to a power-on state, reading target metadata from FLASH and storing it in RAM; If yes, modify the target metadata in RAM; wherein, the enable command is a command for the host to command the SSD to enter the running state. After the method reads the target metadata from FLASH and stores it in RAM, it does not rush to modify and save the target metadata, but detects whether the enable command sent by the host is received; when the enable command is received, it indicates that there is currently Read or write operations, modify and save the target metadata at this time, thereby avoiding unnecessary modification and saving of metadata, and improving the stability of metadata. Correspondingly, a metadata storage device, device, and readable storage medium disclosed in the present invention also have the above-mentioned technical effects.
