Description

Method and device for calling document library system

The present invention relates to document library technology, and more particularly to a method and apparatus for calling a document library system. Background technique

The Chinese patent application with the application number 200910076749.3 provides a client/server model based unstructured data (UMML) processing system and unstructured data (UMML) processing method. In this patent application, a system for implementing a network call document library based on UOML is disclosed, which system is composed of a client and a remote server. The client is configured to receive a predefined instruction from the application software, invoke a corresponding function in the client component according to the predefined instruction, and/or perform network communication with the server, to invoke a corresponding function in the server. The server is configured to perform network communication with the client, and provide a corresponding function according to the call of the client; the predefined instruction is independent of the storage form of the unstructured data.

In this way, when the local application wants to call the remote document library, the local application uses UOML to call the API interface of the client component, and the client component resolves the UOML, and then uses the custom protocol to communicate with the remote document library system. Finally, the local application software is operated on the remote document library system.

Although the existing method implements the operation of the remote document library system, the local application software does not directly call the remote document library system through UOML, so that the remote document library system itself loses the document interoperability brought by using UOML.

In addition, due to the use of the client component of the document library system, the application scope of the remote document library system is also limited, for example, if the application software is a Java program or a browser application, and the client component of the document library system provides a C++ version. API, the application software cannot call the remote document library system by calling the client component of the document library system. And if you develop a document library that supports various programming languages The system will increase the development cost of the remote document library system.

The above prior art problems are caused by the inconsistency between the way in which the local document library is called by UOML and the way in which the remote document library is called. Summary of the invention

To this end, an embodiment of the present invention provides a method and apparatus for invoking a document library system, which can directly call a remote document library system through UOML, realize a method of calling a local document library through UOML and a method of remote document library, and improve remote calling. s efficiency.

Specifically, the embodiment of the present invention provides a method for calling a document library system, including: mapping a UOML operation instruction to a network request conforming to a network protocol;

The network request is sent to the remote document library system for its corresponding operation on the document data.

An embodiment of the present invention further provides an apparatus for calling a document library system, including:

The first module is applied to the local application side for mapping UOML operation instructions to network requests conforming to the network protocol;

The second module: applied to the local application side for mapping UOML operation instructions to network requests conforming to the network protocol.

The embodiment of the present invention fully utilizes the network service transmission protocol independently of the programming language and UOML's own document interoperability, and realizes that the local program (including the browser application M uses UOML to directly call the remote document library system resource to operate; therefore, The technical solution disclosed by the embodiment of the invention encapsulates the intermediate link of the local application calling the remote document library system, realizes the unification of the way of calling the local document library through the UOML and the way of the remote document library, and improves the remote calling efficiency. Description

FIG. 1 is a flowchart of a method for calling a document library system according to an embodiment of the present invention. detailed description

The present invention will be further described in detail below with reference to the drawings and embodiments.

The embodiment of the present invention maps a UOML operation instruction to a network service protocol network request through a network service platform, and sends the network request to a remote document library system; the remote document library system remaps the received network request to a remote document library. An instruction recognized by the system programming language to perform a corresponding document operation according to the instruction.

FIG. 1 is a flowchart of a method for calling a document library system according to an embodiment of the present invention. As shown in Figure 1, the method specifically includes:

Step 101: The local application calls the web service of the remote document library system.

In general, Web Services uses protocols such as Single Object Access Protocol (SOAP), Remote Procedure Call Protocol (XML-RPC), and Lightweight Remote Procedure Call Protocol (JSON-RPC).

Step 102: The local application maps the UOML operation instruction to a network request conforming to the Web Service protocol, and sends the network request to the remote document library system.

The UOML operation instruction includes an action of a UOML operation instruction and an object of a UOML operation instruction.

In an embodiment of the present invention, the UOML operation object is mapped to a composite data type of the Web Service protocol, specifically, the attribute of the UOML operation object is mapped to a single data type variable or complex data in the composite data type of the Web Service protocol. The type variable, the child element of the UOML operation object corresponds to the single data type variable or the composite data type variable in the composite data type; meanwhile, the UOML operation action is mapped to the single data type variable in the Web Service protocol, which may be A single single data type, or a single data type variable in a data type. In this embodiment, the network request can be in the form of HTTP. In another embodiment of the present invention, the WebService protocol calling function provided by the document library system may be invoked, and the UOML operation instruction object is assigned to the parameter of the WebService protocol calling function; specifically, the attribute mapping of the UOML operation instruction object may be For a single data type variable or a complex data type variable in a composite data type of the Web Service protocol, a child element of the UOML operation object corresponds to a single data type variable or a composite data type variable in the composite data type. In an embodiment of the present invention, the same function call address may be provided for all UOML operations, such as http://docbase.xxx.com/action.jsp, and different actions in the UOML operation instruction are mapped to the function call address. Different function names. In another embodiment of the present invention, different calling function addresses may be assigned to different UOML operation objects, such as a URL: http://docbase.xxx.com/UOML instruction name. jsp.

Step 103: The remote document library system remaps the received network request to its recognizable programming language instruction and operates on the document data according to the instruction.

Step 104: The remote document library system maps the operation result to generate a UOML return instruction to a network request of the Web Service protocol, and sends the network request to the local application.

Step 105: The local application parses and determines whether the document library system successfully operates the document data according to the returned network request.

A method for calling a document library system disclosed in the above embodiment of the present invention is described below by taking a remote document library as an example.

The Web Service of the remote document library system uses XML-RPC as the transport protocol to transmit a UOML command that opens the document (Open), including:

Step 1: The local application generates an Open UOML instruction, and encapsulates the instruction according to the XML-RPC protocol, that is, according to the above step 102, the instruction is encapsulated into an instruction conforming to the XML-RPC transmission protocol, and the XML string is as follows:

<?xml version="1.0"?> <methodCall>

<param>

<name> create</name>

<value>< boolean > false </ boolean ></value>

</member>

<name>del_exist</name>

<value>< boolean > false </ boolean ></value>

</member>

</member>

</struct>

</param>

</params>

</methodCall>

As can be seen from the above program segment, the method name of the Open instruction is mapped to the single data variable in the XML-RPC protocol - Method Name, and the operation object of the Open instruction is mapped to the composite data type in the XML-RPC protocol. - Structure parameters. Step 2: The local application sends the encapsulated Open command to the remote document library system by way of HTTP request;

Step 3: The remote document library system receives the HTTP request and parses the Open instruction according to the XML-PRC protocol, and remaps the Open instruction to the instruction of the programming language recognized by the remote document library system;

Step 4: The remote document library system opens the document according to the document library system path included in the parsed instruction, and generates a UOML RET instruction, and encapsulates the UOML RET instruction according to the XML-RPC protocol, and encapsulates the encapsulated The UOML RET instruction is returned to the local application as an HTTP request; the handle part of the UOML RET instruction encapsulated by the XML-RPC protocol is described by a URI, and the XML string is as follows:

<?xml version="1.0"?>

<param>

<name> SUCCESS </name>

<value>< boolean > false </ boolean ></value>

</member>

<name> handle </name>

<valuexstring>http://docbase.com/base/test.sep </ stringx/value></member> </param>

</params>

</methodResponse>

Here, since the remote call cannot save the object handle, the URI or DOI can be used to uniquely specify a specific object in the document library system, and it is the use of the document library system that the processing object of each instruction can be a fine-grained object. In this way, multiple objects of the same document or multiple attributes of an object can be processed by multiple network requests, which reduces the programming difficulty and the amount of data transferred at one time.

Step 5: The local application receives the returned HTTP request, parses the UOML RET instruction according to the XML-PRC protocol, and resolves whether the remote document library is successfully opened.

In another embodiment of the present invention, the process of step 1 and step 2 above may further be: calling an XML-PRC-compliant calling function of a remote document system URL of http:〃 docbase.xxx.com/action.jsp, Assign a value to the function parameter, such as mapping the action Open to the method name, and mapping the object of the Open instruction to the structure parameter.

Alternatively, when there is a call function prototype for each action on the remote document library system side, the XML-PRC protocol-compliant calling function with the remote document system URL of http:〃 docbase.xxx.com/open.jsp is called.

Although the above embodiment uses XML-RPC as an example, those skilled in the art can understand that other Web service protocols still apply.

The embodiment of the present invention further provides an apparatus for invoking a document library system, where the apparatus includes: a first module: applied to a local application side, configured to map a U0ML operation instruction to a data type of a network request in a network protocol;

The second module: is applied to the local application side, and is used to send the network request to the remote document library system for operation on the remote document library system. The device also includes:

The third module is applied to the remote document library system side, and is configured to re-map the received network request according to the network protocol to the remote document library system to recognize the instruction, and operate the document data according to the instruction;

The fourth module: is applied to the remote document library system side, and is used to remap the UOML return instruction generated by the operation result to the network protocol network request, and return the network request to the local application.

The device also includes:

The fifth module is applied to the local application side for receiving the network request returned from the remote document library system, re-mapping the network request into a UOML return instruction, and parsing whether to implement the operation on the remote document library system.

The method for invoking a document library system provided by the embodiment of the invention fully utilizes the network service transmission protocol independently of the programming language and the UOML document interoperability, and realizes direct use of the UOML in a local program (including a browser application). Remote document library system resources operate; in this case, the remote document library system can be described in languages such as Java, PHP, Python, etc., while local applications can use different languages such as C++, C#, JavaScript, etc. than the remote document library system. Description, as long as the local application and the remote document library system can communicate according to the network transport protocol of the Web Service;

Therefore, the technical solution disclosed in the embodiment of the present invention encapsulates the intermediate link of the local application calling the remote document library system, realizes the unification of the way of calling the local document library through the UOML and the remote document library, and improves the remote calling efficiency.

The above are only the preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and scope of the present invention are intended to be included within the scope of the present invention.
