The results of our semantic analysis are shown below using the website's language.

They are the main concepts covered by

Each concept has a confidence score. The higher it is, the more important the topic is relative to the page.

OSDN Confidence: 91% Arrow up

OSDN (formerly SourceForge.JP) is a web-based collaborative development environment for open-source software projects.

It provides source code repositories and web hosting services.

With features similar to SourceForge, it acts as a centralized location for open-source software developers.

Git Confidence: 86% Arrow up

Git is a version control system (VCS) for tracking changes in computer files and coordinating work on those files among multiple people.

It is primarily used for software development, but it can be used to keep track of changes in any files.

As a distributed revision control system it is aimed at speed, data integrity, and support for distributed, non-linear workflows.

Open-source software Confidence: 85% Arrow up

Open-source software (OSS) is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose.

Open-source software may be developed in a collaborative public manner.

According to scientists who studied it, open-source software is a prominent example of open collaboration.

Concurrent Versions System Confidence: 83% Arrow up

The Concurrent Versions System (CVS), also known as the Concurrent Versioning System, is a client-server free software revision control system in the field of software development.

A version control system keeps track of all work and all changes in a set of files, and allows several developers (potentially widely separated in space and time) to collaborate.

Dick Grune developed CVS as a series of shell scripts in July 1986.

Apache Subversion Confidence: 83% Arrow up

Apache Subversion (often abbreviated SVN, after its command name svn) is a software versioning and revision control system distributed as open source under the Apache License.

Software developers use Subversion to maintain current and historical versions of files such as source code, web pages, and documentation.

Its goal is to be a mostly compatible successor to the widely used Concurrent Versions System (CVS).
