JSON (JavaScript Object Notation) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data.

• The user profiles are set up automatically (e.g. the users firstname, surname and email address is inserted the first time a user logs in)
• The user profiles can automatically kept up-to date all the time
• So you don't have to care anymore for user management issues because this is basically handled by the Identity Provider of the Shibboleth user (e.g. the home university).
• Once Shibboleth users are authenticated, they can access other Shibboleth-enabled resources without loggin in another time. Due to this single sign-on mechanism, they e.g. can jump from one Moodle installation to another or the can access a Shibboleth-protected library or a web shop, always being authenticated.

• Automatic course enrollment according to Shibboleth attributes.
