During my time as a developer I’ve seen a need for better permission models in practically every framework and CMS I’ve worked with. Therefore I have created a permission model of my own to fill that need. Among its features is support for logic gates which makes it possible to piece together combinations of permissions in an elegant way.
Since this need transcends language barriers I have created multiple versions of the library. One can then integrate it in frameworks that are written in these languages. The library is open source and free of charge to use.
