Embodiment Construction

[0055] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0056] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0057] To achieve heterogeneous information sharing, a hybrid model is firstly proposed, which consists of two parts: fixed model and custom model.

[0058] The fixed model adopts the Dublin Core metadata model DC, and the model set is selected from a subset of the Dublin Core metadata set. The definition of the subset is shown in Table 1 below, and the meaning follows the original definition.

[0059] Table 1. ICover fixed model metadata set...

Abstract

The invention discloses an information sharing method. A system based on the method comprises an information issuing device, an information packing device and an element model manager, wherein the element model manager is in charge of managing element model information, accumulating element model varieties and providing an interface for users to work by the information packing device; the information packing device is used for receiving the input of information sharing users, combining into issuing information or inquiry information based on element models and finishing packing the issuing information or the inquiry information; the information issuing device is in charge of searching and matching the issuing information stored in nodes which apply the sharing system under a P2P environment, distributing unique identification IDs to the issuing information under the P2P environment and providing a distributed data access interface function to the information sharing users. By using the system, the edge resource of a network can be thoroughly used, an information sharing range is enlarged and the support and the possibility are provided for really sharing the information of any resource unlimitedly on the network.

Description

technical field [0001] The present invention relates to the field of network communication, in particular to a novel network information sharing environment and an information sharing method Background technique [0002] Information is the most important resource that people use computers to obtain, and it is also a purposeful resource. Today, with the rapid development of modern information technology and network technology, people hope to share information to a greater extent, and to obtain and use information as a resource with higher efficiency. People's use of information has already developed from a single user and a single information source to multi-user and multi-channel information sharing. From the current environment and application types of information sharing, there are three main categories: [0003] One is to use the enterprise-wide database as the source of information sharing resources, aiming at the specific application field of the enterprise, and establ...
