Open Permissions Platform
= "an open, online digital rights service".
"The Open Permissions Platform is a microservice architecture implementation of an open, online digital rights service. The service is accessed using REST APIs. The Open Permissions Platform is an implementation of the Open Digital Rights Language (ODRL), a proposed language from the W3C for the standardisation of expressing rights information over content. The Open Permissions Platform project is a full open source implementation of a rights repository with indexing and query services, applicable to any type of works in which rights can be held — including images, music, video, film, books and written works, as well as virtual goods and other pure digital creations.'
