  • step S 905 the import service system determines whether the data structure is coincident with the size already defined in the DB. If the data structure is not coincident with the size defined in the DB (NO in step S 905 ), the import service system does not perform writing for the item. The processing returns to step S 901 to parse the next item.
  • step S 906 the import service system writes the value of the item into the policy DB. In this case, the Archive bit of the meta-information changes to 1.
  • step S 907 the import service system determines whether the writing processing for all items has been completed. If there is not any item value to be written to the policy DB (NO in step S 907 ), the import service system terminates the processing of the flowchart illustrated in FIG. 9 . If any item value to be written is present (YES in step S 907 ), the processing returns to step S 901 to parse the next item and continues to write data into the policy DB.
  • step S 1001 the import service system acquires device identification information (e.g., model management number (or model code) and machine body management number (or serial number)) of the apparatus that has performed the export processing, with reference to the additional information of the XML file.
  • device identification information e.g., model management number (or model code) and machine body management number (or serial number)
  • step S 1002 the import service system reads and acquires device identification information (e.g., model management number and machine body management number) of the apparatus itself.
  • the import service system determines an import level based on the device identification information acquired in step S 1001 and step S 1002 , in the following manner.
  • step S 1003 the import service system determines whether the model management number described in the XML file is coincident with the model management number of the apparatus itself. If the model management number described in the XML file is not coincident with the model management number of the apparatus itself (NO in step S 1003 ), the import service system determines that the import has been performed from another model. Then, in step S 1005 , the import service system sets the import level to 3.
  • step S 1004 the import service system compares the machine body management number described in the XML file with the machine body management number of the apparatus itself. If coincidence is not confirmed in the machine body management number (NO in step S 1004 ), the import service system determines that the setting information has been acquired from a same model apparatus having another machine body number. Then, in step S 1006 , the import service system sets the import level to 2. If coincidence is confirmed in the machine body management number (YES in step S 1004 ), the import service system determines that the processing is for backup re-storage of its own model. Then, in step S 1007 , the import service system sets the import level to 1.
  • FIG. 11 An example of the data loading processing (i.e., the processing to be performed in step S 806 ) is described below in detail with reference to a flowchart illustrated in FIG. 11 .
  • the processing illustrated in FIG. 11 can be called as one of sequentially performed processing in a single task or can be executed simultaneously for a plurality of tasks.
  • the number of executions with respect to the processing illustrated in FIG. 11 is equal to the number of applications ( 402 ) that are present in the device.
  • step S 1101 the import service system confirms the import level determined in the processing described with reference to FIG. 9 . Then, the module corresponding to each application in the apparatus itself repeats the processing of step S 1102 and subsequent steps to import a setting to be reflected, which is included in the XML file (i.e., the setting information) together with its value.
  • step S 1103 the module corresponding to each application inquires the DB about an arbitrary item to check the presence of a secondarily stored setting stored in the policy DB. More specifically, the module determines whether the Archive bit 701 is raised. If the presence of any secondarily stored setting is not confirmed (NO in step S 1103 ), the module checks the next item. If the presence of the secondarily stored setting is confirmed (YES in step S 1103 ), then in step S 1104 , the module acquires the setting and confirms level information included in the meta-information of its key defined in the policy DB.
  • step S 1105 the module compares the import level confirmed in step S 1101 with the key level of its key and determines whether the setting is importable. For example, if the meta-information defined for the key is key level 1 (i.e., backup re-storage for the same machine is enabled) and import level 3 (i.e., an import from a different model), the import is not feasible. Therefore, the module checks the next item without importing any setting.
  • key level 1 i.e., backup re-storage for the same machine is enabled
  • import level 3 i.e., an import from a different model
  • step S 1106 in which the module writes the setting to the storage.
  • step S 1201 the system initializes the policy DB 310 .
  • no value is written in the “Value” field.
  • step S 1202 an export instruction is sent to the module 402 of each application.
  • each module extracts setting information from the storage 403 and writes the extracted information to the policy DB 310 .
  • the module writes all of the related data to the policy DB 310 without considering the level added in the import processing.
  • step S 1204 the module extracts device identification information of the apparatus itself and writes the extracted information to the policy DB.
  • the device identification information includes model management number and machine body management number (SN).
  • step S 1205 the module converts the setting information written to the policy DB into XML format data and generates the XML file 401 .
  • a second exemplary embodiment of the present invention is characterized in that a further unique determination is performed in the above-mentioned import level determination processing (see step S 804 ). More specifically, in the import of the setting information, the present exemplary embodiment intends to import setting information appropriately considering device identification information other than the model management number (or model code) and the machine body management number (or serial number).
  • FIG. 13 illustrates a list of information usable as determination factors of the import level in the present exemplary embodiment. More specifically, the determination factors of the import level includes various information relating to the image forming apparatus, such as firmware version, destination information, paper size standards information, policy DB version, user editing information, accessory connection information, and license information.
  • the determination factors of the import level includes various information relating to the image forming apparatus, such as firmware version, destination information, paper size standards information, policy DB version, user editing information, accessory connection information, and license information.
  • FIG. 14 is a table that illustrates examples with respect to the import level determination based on the determination factors illustrated in FIG. 13 .
  • an item indicated using a hyphen “-” is a “Don't Care” item whose content is not cared.
  • the system determines the import level with reference to the table illustrated in FIG. 14 .
  • the table illustrated in FIG. 14 indicates that an appropriate import level is determined based on each combination of a plurality of determination factors.
  • the meaning of the import level is similar to that described in the first exemplary embodiment. More specifically, level 0 indicates that the import is disabled, and level 1 indicates that the backup re-storage for the same apparatus is enabled. Further, level 2 indicates that an import from the same model is enabled, and level 3 indicates that an import from a different model is enabled.
  • the import level is set to “1” regardless of the state of other determination factors.
  • the import level “1” expresses the policy that information edited by a user is accepted entirely.
  • the user editing information is “NO” and the destination information is “coincident with” that of the device that is performing an import operation.
  • the model management number is “not coincident with” that of the import executing device.
  • the import level is set to “3.”
  • the case 2 indicates a behavior similar to the import from a different model described in the first exemplary embodiment.
  • the user editing information is “NO” and the destination information is “coincident with” that of the import executing device.
  • the model management number is “coincident with” that of the import executing device.
  • the machine body management number (SN) is “not coincident with” that of the import executing device.
  • the firmware version is “newer than the specific version.”
  • the import level is set to “2.” The case 3 indicates a behavior similar to the import from a different machine of the same model described in the first exemplary embodiment.

  • the user editing information is “NO” and the destination information is “coincident with” that of the import executing device. Further, the model management number is “coincident with” that of the import executing device. Further, the firmware version is “older than the specific version.” In the case 5, the import level is set to “3.” The case 5 expresses a policy that causes a behavior comparable to a different model because the firmware is old although the model is the same.
  • the user editing information is “NO” and the destination information is “not coincident with” that of the import executing device.
  • the import level is set to “0.” In other words, no import can be accepted in the case 6.
  • the settings of the table illustrated in FIG. 14 are arbitrarily settable considering various policies.
  • the firmware version i.e., one of the determination factors referred to in the cases 3, 4, and 5
  • setting information to be operated may be differentiated due to the different in the firmware version even if the model is the same. More specifically, in a case where the specification is greatly changed due to version-up, importing information having been backed-up when the firmware is an older version to the same model of a new version is regarded as an import from a different model.
  • flag information indicating that editing has been performed by the user is used as a setting attribute in an XML file. If the flag is raised, the import level is set to “1” so that the setting information can be imported unconditionally. Thus, it is feasible to prevent a control that blocks the user's intended editing (i.e., a control that prevents the user's intended editing from being reflected).
  • the import level can be determined appropriately. Similar to the first exemplary embodiment, it is feasible to determine whether to perform the import processing actually while comparing the determined import level with level information of each key defined in the policy DB 310 .

More specifically, the system enables a user to select a desired one of different model oriented/same model oriented/backup re-storage with respect to the usage of the setting information to be exported, and determines the export level based on the user's selection.
  • step S 1503 an export instruction is sent to the module 402 of each application. If the export instruction is received, then in step S 1504 , each module extracts setting information from the storage 403 and writes the extracted information to the policy DB 310 .
  • the present exemplary embodiment is different from the above-mentioned exemplary embodiment in that the export level is referred to in extracting the necessary setting and writing the extracted setting to the policy DB.
