The document describes the ALISS engine, which aims to improve access to health and social care information in three ways:
1. By serving as a central hub for aggregating information from various sources to make it easier for people to find.
2. By having an open platform that allows for innovative new services and resources to be built on top of the data.
3. By enabling users and communities to actively contribute information and resources, rather than just being passive recipients, to build a more participatory system.
The ALISS engine provides services, moderation tools, and storage capabilities to support these goals.
