Embodiment Construction

[0042] The present invention will be further described below in conjunction with drawings and embodiments.

[0043] A service-oriented metadata association extraction management method, the specific steps are as follows:

[0044] 1. Extract metadata. Acquire data from data sources, convert and map data sources according to international metadata format standards, and automatically generate metadata. This step is further explained as follows:

[0045] a. Data source acquisition. Data sources come from various types and properties of different databases, data files, data dictionaries and other related data including manually entered data.

[0046] b. Format of metadata. According to the content of the data source, select the corresponding international standard as the metadata format.

[0047] c. Automatic generation of metadata. According to the international standard format of metadata, the data source describes different resources with a unified metadata model in the fi...

Abstract

The invention relates to a service-oriented metadata relevance extraction management method and management system. Relevance extraction and classification are performed on metadata, so that a metadata base can be organized and managed effectively, and the information organization is flexible and effective. Based on the principle of service-oriented, information integration and sharing of a heterogeneous platform are achieved. According to the current metadata technology, the metadata interoperability exists when resource retrieval and resource utilization are performed among resource systems described through different metadata formats, and therefore, interpretation and conversion of a plurality of metadata formats and transparent retrieval among information systems described through different metadata formats are included. According to the method and the system, a loosely coupled architecture is built, application functions are defined into callable independent services, states and contexts among the services are independent mutually, the communication among the services is based on standard and accurate interfaces, and accordingly, integration and sharing of heterogeneous information are achieved.

Description

technical field [0001] The invention relates to the technical field of data information processing, in particular to a data processing method for metadata. Background technique [0002] In the face of a large number of information resources, how to organize, manage and utilize them is a problem that information resource users are very concerned about. Under the background that people urgently need to solve the disorder of information resources, the concept of metadata is proposed. Metadata is data about data that describes information resources or data objects. It is generated to effectively solve the problems existing in network resource retrieval. Its purpose is to identify resources, track resources, and evaluate changes in resources during use. Realize the effective discovery and search of information resources and the effective management of resources used. [0003] Metadata can effectively retrieve and control disordered digital information, and provide a new method f...
