In FIG. 1, a Web application system according to an embodiment of the present invention is configured by connecting a mobile terminal device (client) 1 and a Web server 2 through a network 100.

  The mobile terminal device 1 includes a content storage unit 11, a content reading unit 12, a content interpretation execution unit 13, a communication unit 14, a storage device 15, and an output device 16. The processing operations of the content storage unit 11, the content reading unit 12, and the content interpretation execution unit 13 of the portable terminal device 1 can be realized by a program that can be executed by a computer such as a CPU (Central Processing Unit) (not shown).

  The content storage unit 11 acquires content from the Web server 2 and stores it in the corresponding area of the storage device 15. The content reading unit 12 reads the corresponding content from the Web server 2 or the storage device 15. The corresponding content can be specified by a URL (Uniform Resource Locator).

  The content interpretation execution means 13 interprets and executes the content read by the content reading means 12, stores data in the storage device 15 and outputs the result to the output device 16 as necessary. The content interpretation execution means 13 defines a variable with a specified variable name or type and sets its value according to the description in the content. The content interpretation execution unit 13 manages one or more defined variables as a variable group. Further, the content interpretation execution means 13 refers to the value of the designated variable from the variable group based on the description in the content. Here, the variable indicates a memory location where a value can be stored.

  Note that the variable group is inherited when the content interpretation execution unit 13 transitions to another content by the description in the content, and the variable group can be accessed from the transition destination content. Depending on the description of the content, it is possible to prevent the variable group from being taken over by the content at the transition destination.

  Further, the content interpretation execution means 13 can refer to the permanent variable group from other contents by storing one or more designated variables in the storage as a permanent variable group according to the description in the content. Here, the permanent variable group indicates a variable group in a nonvolatile state that is stored in a storage or the like and does not disappear even when the power is turned off.

  Furthermore, the access right to the above-mentioned persistent variable group is defined in the content, and the variable in the persistent variable group can be accessed from other content having the access right.

  In the storage device 15, the content storage unit 11 stores each content, and the content interpretation execution unit 13 stores data (content itself, one or a plurality of variables) according to the execution of the script.

  FIG. 2 is a sequence chart showing the operation of the Web application system according to one embodiment of the present invention, and FIG. 3 is a flowchart showing the operation of the mobile terminal device 1 of FIG. 4 and 5 are diagrams showing an example of content according to an embodiment of the present invention. The operation of the Web application system according to the embodiment of the present invention will be described with reference to FIGS. Note that the processing operation shown in FIG. 3 can be realized by the CPU of the mobile terminal device 1 executing a program.

  First, a client-side application (hereinafter referred to as a terminal application) constituting the Web application system according to the present embodiment is downloaded from the Web server 2 to the mobile terminal device 1 (see a1 in FIG. 2) (step S1 in FIG. 3). ).

  This terminal application is set to call a script on the Web server 2 (see a3 and a4 in FIG. 2) when it is first activated (see a2 in FIG. 2) (step S2 in FIG. 3). When the script called by the terminal application is executed (see a5 in FIG. 2), the content storage unit 11 is activated by this script (see a6 in FIG. 2), and one service providing a service by the content storage unit 11 is provided. A collection of the above contents is stored in the storage device 15 (see a7 in FIG. 2) (step S3 in FIG. 3). If necessary, this script can store a collection of one or more contents providing another service in the storage device 15 by the contents storage means 11.

  When the registered service is executed in the mobile terminal device 1 (step S4 in FIG. 3), the terminal application is activated (step S5 in FIG. 3), and the content belonging to the corresponding service is executed (step in FIG. 3). S6).

  The content reading means 12 reads online content (content stored in the Web server 2 on the network 100) or offline content (content stored in the storage device 15) and passes it to the content interpretation execution means 13 (step S7 in FIG. 3). The content interpretation execution means 13 interprets and executes the content (step S8 in FIG. 3). In the mobile terminal device 1, the processes of the above steps are executed until the process ends (step S <b> 9 in FIG. 3).

  Interpretation of the description regarding the variable on the content will be described using the example of the content description shown in FIGS. 4 and 5 exemplify contents A, B, and C that operate in the Web application system according to the present embodiment. It is assumed that the content B is a transition destination of the content A, and the content C is given an access right to the permanent variable group of the content A.

  FIG. 4A shows a part of the content A (the number at the end of the line is given in the description). The content interpretation execution means 13 interprets the definition of the variable “a” by the line (1) and stores the variable name a and its value “50” in the variable group. At this time, if the variable “a” is already defined, “50” is stored in the defined variable “a”.

  The content interpretation execution means 13 refers to the value of the variable “a” from the variable group and outputs it to the output device 16 in line (2). The content interpretation execution unit 13 changes the value of the variable “a” from “50” to “100” according to the line (3). The content interpretation execution means 13 stores the variable “a” in the storage (storage device 15) as a permanent variable group “sample” according to the line (4).

  The content interpretation execution unit 13 interprets the variable “a” to be deleted by the line (5), and deletes the variable “a” and its value from the variable group. The content interpretation execution means 13 interprets the content B as a transition to “b.xml”, which is a part of the content B, and executes the transition by the line (6). The transition to “b.xml” inherits the variable group by the notation “true” in the line (6).

  FIG. 4B shows a part of the content B. Since “b.xml” which is a part of the content B takes over the variable group when transitioning from the content A, the content interpretation execution unit 13 sets the value of the variable “a” to the variable group according to the line (7). And output to the output device 16.

  FIG. 5 shows a part of the content C. The content C does not transit from the content A or the content B, but since the access right to the permanent variable group of the content A is defined, the content interpretation execution unit 13 performs storage (storage device) by the line (8). From 15), the permanent variable group “sample” can be read, and the value of the variable “a” can be output to the output device 16 (line (9)).

  In this way, in this embodiment, variables can be used without considering the processing on the Web server 2 side by defining, referencing, updating, and deleting variables with a fixed syntax in the content. Since it is possible to specify that these variables can be referred to or cannot be referenced across the contents, it is possible to easily construct the contents using the variables.

  Further, in the present embodiment, necessary variables can be stored in the storage (storage device 15) on the mobile terminal device 1 side, and the content permitted to access the variables is stored in the storage device 15. Since the variable can be referred to, the content can be browsed even when there is no communication (offline) between the mobile terminal device 1 and the Web server 2.

  In addition, the present Example can construct | assemble the content which can be utilized on the portable terminal device 1 easily. For example, when considering a service that provides a coupon, the presence or absence of a coupon is defined as a variable, and content that refers to the variable is prepared, so that the user does not access the Web server 2. The coupon status (presence / absence) can be confirmed.

It is a block diagram which shows the structure of the web application system by one Example of this invention. It is a sequence chart which shows operation | movement of the web application system by one Example of this invention. It is a flowchart which shows operation | movement of the portable terminal device of FIG. It is a figure which shows an example of the content by one Example of this invention.
