Re: Moving Forward with Agentic Linked Data

Joshua,



(I'll jump in for Kai on this)



"- In your DTwin: is your pod used to replicate a catalogue or are you also incorporating operations (like monitoring)?"



We use a lower level RDF ontology (Linked Data Hypergraph LDH) to capture all space-time for a part of the world (both documents about it and system twin) represented by a pod where events take states as input and output and events execute capabilities of systems performing functions.  A state can (and is) serialized as a triple, but has a unique uri as do all objects allowing very fine grained access control with WAC.  



We have a master server at graphmetrix.net that manages the source of truth for the neo ontology, the internet digital twin pod, and server and app specs.  Changes made to these pods are then broadcast to all trinpod servers via wss.  The internet digital twin pod captures all the servers, ports, and pods for all trinpod servers and is needed as well as the ontology and other specs when servers start up for configuration.  Whenever new pods are created on any TrinPod server, the internet digital twin is updated and updates are broadcast to the whole network.  This prevents users from using the same email on multiple TrinPods for example.  All TrinPod servers have their own digital twin pod that captures all the changes and events of that server.



"- Did you a"lso build some ReBAC to manage the access from pod-to-pod?



We use the Solid Spec WAC for all access control down to the triple level.



My best,

Fred

A couple of questions: 
 
- In your DTwin: is your pod used to replicate a catalogue or are you also incorporating operations (like monitoring)? 
- Did you also build some ReBAC to manage the access from pod-to-pod?

 For context, at Graphmetrix we use Pods with WebIDs for any entity we want to manage as a Digital Twin. 
 Currently we are targeting the Build industry, for that we use Person, (Employee), Group, Business, Organization, Sub-Organization, Site, Building and Project Pods. But going forward we will enable pod creation for any entity needed, like a bicycle, an oil platform, any entity. 
 The only pod you can sign into is the Personal Pod, then your personal Pod (you) can have access to other Pods, or content in other pods. 
 
 Here is an example. Bob Doe is a personal pod, signed into. 
 Bob is employed at Graphmetrix Inc, so Bob gets access to it. 
 Graphmetrix has two Project pods that Bob has access to. 
 
 
 Each Pod gets the benefits of Solid, so a company also can own and control their data while securely controlling the sharing of information in it, having their data separate from the apps etc..
