Suggestion to extend the homepage: Add bullet points for important features/services

[jh-RLI]

Description of the issue

In the past, the question has often arisen as to what content the OEP actually offers. The question always comes up particularly when someone has had no previous contact with the OEP's content work. For this reason, we first created an overview of our ‘products/services’ on the OEP homepage. Later we added courses and the academy and then the compendium.

In my opinion, a very short summary that is displayed on the OEP homepage is still missing. It should clearly list the benefits / Use cases of the OEP for users.

Ideas of solution

Not complete/compact, but that's what I had in mind:

Database:

• free data storage of openly licensed data
• Support for relational tabular data formats (frictionless data)
• Extensive metadata can be used to describe data from the field of energy research
• Open Peer Review for uploaded data(metadata) resources
• Creation of link data by linking further resources from the OEO or external resources to describe your tabular data

Scenario bundle

• Document your modelling process by creating a factsheet about your work
• Provide general information, link publications and create detailed factsheets about the models and frameworks used, describe the scenario your model executes: everything is summarised in a bundle that can be easily shared with others.
• Compare your bundles with others to get a qualitative overview of the similarity
