 ## Involved Devices and Applications
 
-- Siemens Sentron PAC (Modbus)
+- Siemens Sentron PAC (Modbus/TCP)
 - Siemens S7 (OPC UA)
-- Industrial Information Hub (IIH) running on Industrial Edge
-- TDD
+- (potentially other devices available at the Plugfest)
+- Industrial Information Hub (IIH) running on Siemens Industrial Edge (running on Siemens Simatic IPC227E)
+- Domus Thing Description Directory (https://github.com/eclipse-thingweb/domus-tdd-api) reachable at: http://plugfest.thingweb.io:8081/
 
 ## Mashup Explanation
 
-IIH gets the TDs of the devices and their sensor values are automatically shown in a dashboard. To be further refined
+- Plugfest participants (are asked to) upload TDs of their devices to Domus TDD
+- TDs are available at: http://plugfest.thingweb.io:8081/things/{id}
+- Respective Asset Administration Shell (AAS) Submodel is available at: http://plugfest.thingweb.io:8081/submodels/{id}
+- AAS Submodel is formatted as Asset Interfaces Description (AID)
+- IIH loads AID of respective device and connects to it (on the Southbound interface)
+- For the Northbound interface and thus for visualizing the device's value as AAS Asset Interfaces Mapping Configuration (AIMC) can be deployed on IIH
+- Domus TDD can be queried via SPARQL
+
+## Open points, things to be studied during plugfest
+
+- How does Domus TDD behave for different TDs?
+- Does conversion to AAS AID work correctly?
+- Does Southbound connection to various devices work?
+- Can we add other protocols for the Southbound connection?
+- How can an AAS AIMC be created (automatically)?
