Herbrich Ontology – Root-Error as a subclass of GridNodeConnection in the semantic knowledge graph

Herbrich Ontology > GridNodeConnection > Root-Error

Class: Root-Error

A Root-Error is a specialized GridNodeConnection (rdfs:subClassOf) with Type = "ROOT-ERROR". It semantically maps the connection entries returned by the Grid API (/v1/grid/nodes/{HallAddress}/connections) whose Type is ROOT-ERROR. Such an entry is an error signature: it declares that its subject (Name, with the reference Param) is explicitly defined as an error at the root level of the Herbrich Matrix. This is a definition, not an event – it does not imply that the error is currently active.

Properties of Root-Error

Root-Error introduces no additional properties. It is defined entirely by the properties of its connection entry as returned by the Grid API, with the constraint Type = "ROOT-ERROR":

Property	Expected Type	Description	Origin
Id	xsd:string	The GUID of the connection entry (UUID). Identifies the declared error signature uniquely within the Grid.	inherited
Name	xsd:string	The identifier or display name of the Grid connection: the subject that is declared as an error.	inherited
Type	xsd:string	Technical type. Always `"ROOT-ERROR"` for this class – this constraint is what defines the class.	inherited
Param	xsd:string	The reference or payload of the connection entry (e.g. the entity, address, or scope the root-level error declaration points to).	inherited
sourceNode	Node	The Grid Node on which this connection is registered (derived from the API endpoint `/v1/grid/nodes/{HallAddress}/connections`).	own

JSON-LD Example

{
  "@context": "https://www.herbrich.org/ontology/",
  "@type": ["Root-Error", "GridNodeConnection"],
  "@id": "urn:uuid:93bb3f57-9e3e-414b-8606-6f8167f1d6b3",
  "Id": "93bb3f57-9e3e-414b-8606-6f8167f1d6b3",
  "Name": "2. April",
  "Type": "ROOT-ERROR",
  "Param": "St. Ansgar",
  "sourceNode": {
    "@type": "Node",
    "HallAddress": "c2de8ca2-ee41-4fc1-b09c-710d953d845b",
    "NodeName": "Wohngruppe Graumannsweg",
    "HerbrichName": "Herbrich Wohnhaus 3"
  }
}

The @type array makes the derivation machine-readable even without a loaded ontology: every instance is simultaneously a Root-Error and a GridNodeConnection. The example maps a real connection entry from the Grid API; the semantics of the class lie in the Type constraint alone: the entry declares "2. April" (Param "St. Ansgar") as an error defined as such at the root level – without any statement about whether this error is currently active.

Distinction

Class	Meaning
GridNodeConnection	Generic connection entry (arbitrary Type: FACEBOOK, DNS, HSSID, SHC, SYNONYME, …).
JenniFrameLink	Connection with Type JENNIFRAME → callable JenniFrame route.
Snake	Connection with Type SNAKE → reference to the serpent of the Garden of Eden (Genesis 3).
Root-Error	Connection with Type ROOT-ERROR → error signature: an error explicitly declared as an error at the root level; declaration only, not necessarily an active fault.
GridEdge	Directed or undirected edge between two Nodes (Source/Target).
NodeApplication	Technical application running on a Node.
