Documentation/4.0/SlicerApplication/ExtensionCatalogPolicies

Slicer Extensions Catalog

The download site will be called Slicer Extensions Catalog. Extensions Catalog will host two types of extensions:

• Category 1: Released Extensions
• Category 2: open source, contact exists.
• Category 3: all other extensions (work in progress, beta, etc).

The initial presentation when visiting the page will present only Category 1 extensions. Search will allow to search all extensions. The toplevel interface will have a link for developers to the pages describing the requirements.

Requirements for Category 1 Slicer Extensions

Category 1 extensions must meet the following conditions:

• comply with the Slicer License
• compile and install on all platforms supported by slicer
• have test coverage of better than 60%
• have documentation at a level of quality comparable to slicer core modules
• answer emails in relation to the extension which are posted on the two slicer mailing lists.

Requirements for Category 2 Slicer Extensions

Category 2 extensions must meet the following conditions:

• open source
• contact person
• clear declaration about the license under which the code is distributed

Category 3 Slicer Extensions

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 set the module path in Slicer manually.
