Lingue Namespace Document (Version 0.1.1)

Title: Lingue Ontology
Status: Draft 0.1.1 (payload-enabled exchanges, XMPP/MUC focus)

Abstract

Lingue is a lightweight ontology for agents to advertise capabilities, exchange profiles, and negotiate structured or unstructured communication. The initial environment is XMPP multi-user chat; supported language modes include human chat, IBIS-annotated text, Prolog snippets, and RDF-based agent profile exchange.

Namespace

All terms are in the Lingue namespace: http://purl.org/stuff/lingue/ (prefix lng:). Legacy RPP profile terms have been re-minted into this namespace for continuity.

Classes

• lng:Agent — participant in Lingue interactions (subclass of foaf:Agent).
• lng:Profile — RPP-style profile describing runnable or conversational capabilities.
• lng:Component, lng:Availability, lng:Dependency, lng:Environment, lng:Library, lng:Algorithm, lng:Interface, lng:DataFormat, lng:Encoding — re-minted structural classes for process description.
• lng:Capability — advertised ability; lng:Channel and lng:LanguageMode specialize it.
• lng:Exchange — interaction instance (negotiation/ASK/TELL).
• lng:ProtocolShape — SHACL node shapes for validating capability intersection.

Object Properties

• lng:supports (Agent → Capability) — advertised abilities (channels, language modes).
• lng:prefers (Agent → LanguageMode) — preferred outgoing mode.
• lng:profile (Agent → Profile) — links an agent to its profile.
• lng:understands (Agent → rdfs:Resource) — vocabularies/serializations understood (e.g., IBIS, SHACL, MIME IRIs).
• lng:offers / lng:asks / lng:tells (Agent → Exchange) — protocol markers.
• lng:usesLanguageMode (Exchange → LanguageMode) — selected mode for an exchange.
• lng:usesChannel (Exchange → Channel) — selected channel for an exchange.
• lng:payload (Exchange → rdfs:Resource) — structured payload element (RDF or JSON) associated with an exchange.
• lng:dependsOn (Profile → Dependency) — required dependencies; alias lng:hasDependency.
• lng:in / lng:out (Profile → Interface) — input/output description.
• lng:availability (Profile → Availability) — machine-readability level.
• lng:location (Profile → rdfs:Resource) — locator for executables or endpoints.

Datatype Properties

• lng:alang (Algorithm → Literal) — programming or specification language of the algorithm.

Individuals (Controlled Terms)

• Language modes: lng:HumanChat, lng:IBISText, lng:PrologProgram, lng:AgentProfileExchange.
• Channel: lng:XMPPMUC.
• Availability values: lng:Definition, lng:Source, lng:Executable, lng:Process.

Change History

• 0.1.1 — Added lng:payload for structured exchange payload references (RDF/JSON).
• 0.1.0 — Initial Lingue namespace, re-minting RPP profile terms; XMPP MUC and language mode individuals (human chat, IBIS text, Prolog, agent profile exchange); availability controlled terms added.
