I’ve accepted some pull requests from Lorenzo Gil Sanchez, including significant contributions to the SAMLmetaJS. Lorenzo Gil Sanchez has worked with SAMLmetaJS in the context of PEER.
The main change is a plugin based architecture where all editing tabs are separate plugins. Each plugin is a separate js file as well.
The pull request also included a plugin for organization information.
The SAMLmetaJS download page is updated to allow you select which plugins you would like to include, and it generates a single minified file for you.
