Problems solved by technology

For users, in a large service resource library, it is a complex and changeable process to discover and call the data resources of interest through service composition. Developers need to master a large number of service description standards, retrieval technologies, and domain-related knowledge in order to Find suitable composable services, especially the data itself is a kind of complex data, which makes it more difficult for users to utilize data resources
[0004] Because the current SOA platform lacks an intuitive resource view, it is often difficult for users to have transparent and integrated access to the required data resources

Embodiment 1

[0073] 1. Establish a SDD-based Web service data model, the model is designed according to the idea of ​​layered architecture, such as figure 1 As shown, it is divided into 101 analysis layer, 102 control layer and 103 presentation layer.

[0074] 1.1, 101 parsing layer (parse layer): responsible for model initialization and parsing of underlying data. The BPEL file describes the information of the service combination, but the specific service information still needs to be interpreted from the WSDL file, so the source of the analysis layer data is the WSDL and BPEL files of the entire service repository.

[0075] The modules included in the 101 parsing layer are:

[0076] Parser (Parser): responsible for the parsing operation of the service resource library, supports distributed deployment of resources, and can parse XML files on the network. Due to the different element structures between WSDL and BPEL, the parser provides special XML parsing programs for different...

Embodiment 2

[0145] The present invention provides a system based on the model, and the system development and implementation environment is developed based on EclipsePDE (Eclipse Plug-in Development Environment) technology. The loader, parser and SDD analyzer of the model parsing layer all use the log4j technology based on open source to realize the parsing of xml files. The control layer and the view layer use SWT / JFace (Standard Widget Toolkit / JFace) technology to create views to realize the loose coupling between the control layer and the view layer. The drawing of visual graphics uses GEF (Graphical Editing Framework) technology to realize the drawing of parallel coordinates and dot matrix. The system package is packaged as a thick client program through RCP (Rich Client Platform) technology for users to use.

[0146] Taking the following service resource library in the digital campus field as an example to introduce specific embodiments of the present invention

[0147] Selec...

Abstract

The invention provides a web service data modeling and searching method based on SDD (service data description), which comprises the steps of I, establishing a web service data model based on the SDD, wherein the model is divided into a parse layer, a controller layer and an expression layer; and II, providing the web service data searching method described in the specification based on the model.

Description

technical field [0001] The invention relates to a method for modeling and searching Web service data Background technique [0002] With the rapid development and wide application of the Internet platform, the effective utilization of data resources on the Internet has become a major demand of the information society, which has led to the continuous acceleration of the process of computing services. As a technical component of a modern distributed collaborative computing system, "service" supports the on-demand evolution and dynamic reorganization of computing systems through Service-Oriented Architecture (SOA), service computing models and their implementation technologies. In recent years, research related to service computing has emerged in an endless stream, and service composition has always been one of the hot spots in service computing research. Abstract and encapsulate data through services, use service composition to dynamically organize and aggregate rich service r...
