Communication between different layers and communication with third parties or other platforms
is a key point displayed as arrows. Specifically, the key communications are:

• Services Interface: Interface that joins the Service Layers with the Interoperability Layer. The
interface connecting these two layers should be open and standardized. However, as long as
there is no standardized interface, other interfaces can be used optionally. Therefore, in addition
to the open and normalized APIs between these two layers, specific connectors in the Service
Layer could provide specific services.
• Interoperability Interface: Interface connecting the Interoperability and Knowledge Layers.
The interface connecting these two layers must be open and standardized.

• Data/Metadata Collection Interface: Interface connecting the Knowledge and Acquisition
Layers: The interface connecting these two layers must be open and standardized.

o The Acquisition/Interconnection Layer: Offers the mechanisms for the reception of data
from the Capture Systems and is also responsible for allowing interconnection with other
external systems that only consume data and, finally, abstracts the information from the
Capture Systems with a semantic approach.
