The project will deliver training materials for the digital arts and humanities in different languages and make them available via an online e-learning platform. This report elaborates on the implementation of such a platform. It describes the main user scenarios, it collects user and technical requirements, defines the data model and functional specification and explores technical solutions. The report has been created within WP 4 Infrastructure Development with input from all partners, especially WP 2 (user requirements). As a first step, we performed desktop research on what kind of solutions and projects on portals for training materials exist and what kind of systems they are using. The second step was an evaluation of different tools. There are different evaluation methods and criteria for e-learning systems (e.g. Kurilovas & Dagiene 2009). We chose to start from user requirements and a mapping of the user requirements from WP2 to functionalities available in existing systems. Finally, we determined which solution would suit the requirements and other circumstances within the project best.
