OWL → TypeQL 3.x Mapping

OWL Construct	TypeQL 3.x	Example
owl:Class	entity X	entity Organization
rdfs:subClassOf	sub	entity Corporation, sub Organization
owl:ObjectProperty	relation	relation hasMember, relates collection, relates member
owl:DatatypeProperty	attribute	attribute name, value string
owl:FunctionalProperty	@card(0..1)	owns birthDate @card(0..1)
rdfs:domain	plays	entity Person, plays employment:employee
rdfs:range	role type or value	relates employer or value datetime

TypeQL 3.x Syntax (NOT 2.x!)

# Correct 3.x syntax - kind-first declarations
entity Person,
    owns name @key,
    owns birthDate @card(0..1),
    plays employment:employee;

relation employment,
    relates employee @card(1..1),
    relates employer @card(1..1);

attribute name, value string;

Common mistakes to avoid:

• ❌ Person sub entity (2.x syntax)
• ✅ entity Person (3.x syntax)
• ❌ Using rule (deprecated in 3.x)
• ✅ Using fun for inference functions

XSD → TypeQL Type Mapping

XSD	TypeQL
xsd:string	string
xsd:integer	integer
xsd:decimal, xsd:double	double
xsd:boolean	boolean
xsd:date	date
xsd:dateTime	datetime
xsd:anyURI	string (no URI type)

gist Ontology Source

Version: v14.0.0 Local fork: /Users/robert/repos/objectiveous/gist Upstream: https://github.com/semanticarts/gist

Use the local fork - no need to fetch from remote:

# Copy from local fork
cp /Users/robert/repos/objectiveous/gist/gistCore.ttl kg/source/

# Or read directly
cat /Users/robert/repos/objectiveous/gist/gistCore.ttl

Semantic Gaps to Document

These OWL constructs don't map cleanly to TypeQL:

1. Open World Assumption - OWL: unknown ≠ false; TypeQL: closed world
2. owl:disjointWith - No native TypeQL support
3. owl:Restriction - TypeQL properties are global, not class-scoped
4. Automatic Inference - OWL reasoners vs TypeQL explicit functions
5. Anonymous Classes - Unions/intersections need named types

Document gaps in kg/docs/SEMANTIC_GAPS.md

Design Decisions

1. Naming: Preserve gist camelCase (hasMember, isPartOf)
2. Inverse properties: Model as single relation with two roles
3. Restrictions: Skip in Phase 1, revisit in Phase 4
4. Annotations: Store SKOS metadata as attributes (TBD)

Phase 1 Tasks (dots-189.1.*)

• dots-189.1.1 - Fetch and analyze gistCore.ttl v14.0.0
• dots-189.1.2 - Create gistCore.tql schema file
• dots-189.1.3 - Validate schema loads in TypeDB 3.x
• dots-189.1.4 - Document mapping decisions and semantic gaps

Validation

Test schema loads:

# Connect to TypeDB
typedb console --address dots.dots:1729 --username admin --tls-disabled

# Then in console:
> database create dots-test
> transaction dots-test schema write
> source kg/typeql/schema/gistCore.tql
> commit

When Invoked

1. Always read the spec first: kg/FEATURE_SPEC_gist_to_typeql.md
2. Check current bead status: bd show dots-189.1
3. Understand what phase/task we're in
4. Follow the established patterns
5. Document decisions in mapping docs
6. Update beads when completing work
