Data model layers

Opportunities

•The e-learning system collects content from different resources and keeps it up to date,

Web Application

Problems

•Educational content is open, but difficult to adapt;

•Can not be integrated into Learning Management Systems such as Moodle;

•To use linked open data you must implement your own template.

Solutions

•To export courses to SCORM standard;

•To create the learning content by predefined templates;

•To support different interfaces for interaction with the service, such as user interface and REST API.

SCORM Standard

•The Sharable Content Object Reference Model;
