From an OpenAIRE Blog Post:
The new CAP defines the conditions under which metadata of scientific products collected from content providers in OpenAIRE will be considered for inclusion in the OpenAIRE information space. Policies specify which typologies of objects are mapped into which OpenAIRE entities (literature, dataset, software, other research products) and which are the minimal quality conditions under which metadata can be accepted.
Literature, Datasets, Software, other research products
It is important to stress that OpenAIRE collects publications from EC-funded projects as well as every other Open Access (OA) content. In this new CAP version, we expand the scope again to include non-OA content (under certain conditions) too. Specifically, OpenAIRE accepts the metadata records of all scientific products whose structure respect the model and semantics as expressed by the OpenAIRE guidelines. This means that both Open Access and non-Open Access material will be included and links to other products will be resolved where this is possible (i.e. the provided PIDs have a resolver).
