Lingue Ontology (Draft, 0.1.1)

Namespaces and Scope

• lng: — http://purl.org/stuff/lingue/ (all new terms, including the RPP-derived ones).
• RPP classes/properties from http://www.citnames.com/2001/04/rpp# are re-minted under lng: with the same local names to keep continuity while living in the Lingue namespace.
• foaf: — http://xmlns.com/foaf/0.1/; ibis: — https://vocab.methodandstructure.com/ibis#.

Core Classes

• lng:Agent — subclass of foaf:Agent; any Lingue participant (software or human).
• lng:Profile — re-minted RPP Profile for describing runnable or conversational capabilities.
• lng:Component, lng:Availability, lng:Dependency, lng:Environment, lng:Library, lng:Algorithm, lng:Interface, lng:DataFormat, lng:Encoding — RPP-derived structural classes for process description.
• lng:Capability — abstract ability (language, channel, behavior).
• lng:Channel — communication medium; initial individual lng:XMPPMUC.
• lng:LanguageMode — communicative idiom; initial individuals lng:HumanChat, lng:IBISText, lng:PrologProgram, lng:AgentProfileExchange.
• lng:Exchange — an interaction scoped by channel and language mode, with optional negotiation state.
• lng:ProtocolShape — SHACL node shapes for capability intersection.

Core Properties

• lng:supports (Agent → Capability | LanguageMode | Channel).
• lng:prefers (Agent → LanguageMode).
• lng:profile (Agent → Profile).
• lng:understands (Agent → IRI), e.g., ibis:, SHACL, MIME types.
• lng:offers, lng:asks, lng:tells (Agent → Exchange) — protocol markers.
• lng:usesLanguageMode (Exchange → LanguageMode) — language selected for a given exchange.
• lng:usesChannel (Exchange → Channel) — channel selected for a given exchange.
• lng:payload (Exchange → rdf:Resource) — structured payload element (RDF or JSON) associated with an exchange.
• lng:dependsOn (Profile → Dependency), lng:hasDependency (alias if needed).
• lng:in / lng:out (Profile → Interface) — I/O description.
• lng:availability (Profile → Availability) — definition/source/executable/process.
• lng:alang (Algorithm → Literal) — programming or specification language.
• lng:location (Profile → Resource) — locator for an executable or service endpoint.

Controlled Individuals (initial)

• lng:HumanChat — human-readable free text; MIME text/plain.
• lng:IBISText — text with IBIS semantics; MIME text/plain plus IBIS RDF option.
• lng:PrologProgram — Prolog clauses; MIME text/x-prolog.
• lng:AgentProfileExchange — RDF profile payload; MIME text/turtle, application/rdf+xml.
• lng:XMPPMUC — XMPP multi-user chat.
• lng:Definition, lng:Source, lng:Executable, lng:Process — values for lng:availability.

Example (Agent profile and capability advertisement)

@prefix lng: <http://purl.org/stuff/lingue/> .
@prefix foaf: <http://xmlns.com/foaf/0.1/> .
@prefix ibis: <https://vocab.methodandstructure.com/ibis#> .

:room-bot a lng:Agent ;
  foaf:name "Room Bridge Bot" ;
  lng:supports lng:XMPPMUC, lng:HumanChat, lng:IBISText, lng:PrologProgram, lng:AgentProfileExchange ;
  lng:prefers lng:HumanChat ;
  lng:profile :room-bot-profile ;
  lng:understands ibis:, <http://www.w3.org/ns/shacl#> .

:room-bot-profile a lng:Profile ;
  lng:availability lng:Executable ;
  lng:in [ a lng:Interface ; rdfs:label "XMPP <message/> text" ] ;
  lng:out [ a lng:Interface ; rdfs:label "XMPP <message/> text" ] ;
  lng:dependsOn [ a lng:Environment ; rdfs:label "Prosody/XMPP" ] ;
  lng:alang "JavaScript" .

SHACL Intersection (sketch)

• A lng:ProtocolShape targets lng:Agent and asserts at least one shared lng:LanguageMode and lng:Channel via lng:supports, mirroring the negotiation idea in docs/dev-prompts/requirements.md. Use SHACL sh:in or sh:hasValue constraints to validate overlap.

Change Notes

• 0.1.1: added lng:payload to associate structured payloads (RDF/JSON) with exchanges.
