Embodiment Construction

[0037] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0038] refer to Figure 1 to Figure 10 , the method of the present invention comprises the following steps:

[0039] The first step, the construction of the license warehouse,

[0040] By analyzing ten mainstream open source license agreements, and building a license warehouse based on a unified description model of the license agreement, including the analysis of the license terms and the compatibility relationship between the licenses, the ten common open source software licenses are compared to the name , rights, conditions and restrictions are collected and categorized, and stored in the license warehouse.

[0041] The second step, the identification of the license,

[0042] License feature analysis is mainly divided into two aspects, one i...

Abstract

The invention relates to an open source license compliance analysis and conflict detection method, which is mainly divided into the following four aspects: a license identification method: one is a direct identification mode adopting a pattern matching heuristic algorithm, and the other is an indirect identification mode adopting a code matching technology. License information extraction and modeling: as a prerequisite for license compliance analysis and conflict identification positioning, feature information associated with the license agreement is collected in the project. Quantitative Analysis of License Compliance: Find out what is consistent and inconsistent with the license agreement in the mixed-source project, based on the license agreement as a standard. License conflict identification positioning: Using license warehouse, from the license name, rights, conditions and restrictions to identify the license conflict between mixed-source project and open-source standard software,and then positioning to specific open-source project and specific location.

Description

technical field [0001] The invention relates to an open source license compliance analysis and conflict detection method, which belongs to the field of open source license feature analysis. Background technique [0002] Open source software first originated in the 1970s. Students at MIT in the United States often wrote some software for free distribution. No one thought of software rights, let alone commercial behavior. This was the embryonic period of the open source movement. Until the mid-1980s, Richard Stallman initiated the GUN project and founded the Free Software Foundation, thus unveiling the curtain of open source software. [0003] At present, open source software is not only widely used in the open source community, but also widely used as a part of commercial software. Open source is changing the way software is built, enabling components in open source systems to be reused. Because this kind of reuse based on open source code may lead to license conflicts, it ...
