Requirements for Slicer Extensions
Slicer Catalog根据以下条件将所有的extensions 分为了以下的三类
Category 1
Category 1 extensions must meet the following conditions:
- comply with the Slicer License（遵守Slicer许可证）
- compile and install on all platforms supported by Slicer（编译并安装在Slicer支持的所有平台上）
have test coverage of better than 60%. See issue #2172- have documentation at a level of quality comparable to slicer core modules（文档的质量与Slicer的核心模块相当）
- have a designated person to answer emails in relation to the extension which are posted on both the users and developers Slicer mailing lists.（在用户和开发人员的Slicer邮件列表中，有一个指定的人来回复与extension 相关的电子邮件）
- are updated to support new versions of the OS, new versions of packages (such as VTK, ITK), etc.（不断更新以支持版本操作系统、新版本的依赖包(如VTK、ITK等)）
- have clear description, icon, screenshots and tutorials（有清晰的描述，图标，截图和教程）
Category 2
Category 2 extensions must meet the following conditions:
- be available under a compatible open source license（可在兼容的开源许可下使用）
- have a designated maintainer to respond to questions about the extension（有指定的维护人员来回答有关扩展的问题）
- have a clear declaration about the license under which the code is distributed（对代码发布所依据的许可证有明确的声明）
- have documentation page（有文档页面）
- have clear description, icon, screenshots and optionally tutorials（有清晰的描述，图标，截图和可选的教程）
Category 3
Category 3 Slicer Extensions cover everything else, including developers who do not want to share their source code or extensions.
- I do not want to share my source code: When source code is not shared, it is not possible to inspect the code for malicious content. This is a potential security risk that we will not accept for the Slicer website.
- Developers are free to set up their own Midas servers for hosting extensions if they want to host category 3 extensions, or can just make .tar.gz files and either install the package manually from the Extension manager or set the module path in Slicer manually.
- 自己不想公开源码的Extension可以尝试第三种方案
