Abstract

A mashup method is disclosed. The Web APIs which the Web application uses are specified by analyzing descriptions of drivers used to access the multiple Web APIs from a Web application to external devices. A Web Application Programing Interface list is created to indicate the Web APIs. The Web application is analyzed. The external devices including the Web APIs which the Web application accesses are estimated. An external device list which indicates the estimated external devices is created. By referring to the external device list, when one or more external devices do not exist, an access to each of the Web APIs pertinent to the Web application is restricted where the one or more external devices include the Web APIs used in a process of the Web application and the process is realized by mashup.

The mashup method as claimed in claim 1, wherein the restricting of the access includes permitting the access to each of the Web Application Programming Interfaces used by the first Web application when the first and second external devices used by the first Web application do not exist in the detection device list.

3. The mashup method as claimed in claim 1, wherein the Web Application Programming Interface list includes a first Web Application Programming Interface list and a second Web Application Programming Interface list, and

the creation of the Web Application Programming Interface list further includes

creating the first Web Application Programming Interface list by associating with device names of the first and second external devices by specifying functions for calling the Web Application Program Interfaces from the descriptions of the drivers;

and

creating the second Web Application Programming Interface list by associating with URLs for calling the Web Application Program Interfaces with the device names.

4. The mashup method as claimed in claim 1, wherein the creating of the external device list further includes

estimating first and second external devices corresponding to the multiple Web Application Programming Interfaces in a same function in a description of the first Web application as the first and second external devices used for the execution of the first Web application.

5. The mashup method as claimed in claim 4, wherein the creating of the external device list creates the external device list by associating an application name of the first Web application with the estimated first and second external devices for each of the Web applications.

6. The mashup method as claimed in claim 1, wherein the restricting of the access further includes

determining whether another external device opening the same Web Application Programming Interface exists, when at least one of the first and second external devices used by the first Web application does not exist,

displaying, at a user interface, a confirmation screen for confirming to switch to the other external device, when the other external device exists, and

permitting the access to the other external device, when information indicating that the switch to the other external device is received from the user interface.

7. The mashup method as claimed in claim 5, wherein the restricting of the access further includes

blocking the access to the first and second external devices until each of the first and second external devices used by the first Web application becomes available, when the other external device does not exist.
