Motivation
bull Make it easy to read and write queries for OWL ontologies
bull Allow both schema and instance queries
bull Without inventing a completely new query language
bull Not hard to learn
Querying OWL
bull The most commonly used Semantic Web query language is SPARQL
bull SPARQL intended for RDF
bull Semantics based on pattern matching over RDF graphs
bull Semantics extensions possible via entailment regimes
bull SPARQL-DL extension [OWLED 2008 paper]

Terp Grammar
bull Merge SPARQL grammar with Manchester syntax grammar
bull Keep all the syntax features of SPARQL
bull A few cases where ambiguity arises
bull Ex Parentheses are used for lists in SPARQL and for nesting in Manchester syntax
bull Try to resolve ambiguity by the context
bull Assume SPARQL intent otherwise
Implementation
bull Terp parser implemented in Pellet and available as of version 21
bull Integrated through Jena ARQ architecture
bull Can translate any Terp query to regular SPARQL syntax
bull Can be used programmatically or through CLI
Possible Extensions
bull Allow Manchester syntax in predicate position
bull Ex Use equivalentTo instead of owlequivalentClass and owlequivalentProperty
bull Support for additional OWL 2 constructs
bull Ex Negative property assertions axiom annotations
bull More syntactic sugar for frequently used OWL features

bull I want a triple-friendly syntax Use Turtle syntax
bull I donrsquot need your help Use RDFXML syntax
Terp Syntax
bull Combine Turtle with Manchester syntax
bull Use Manchester syntax for expressing class property or datatype expressions
bull Manchester syntax expressions can appear in subject or object position of triples
SELECT wine flavor wine a ( wineWine and winemadeFromGrape min 2 )
Complex Terp Example
bull Query Find meal courses that go with full-bodied wines if exists return the associated label order results by labels but donrsquot include owlNothingSELECT wine flavor mealCourse rdfssubClassOf foodMealCourse foodhasDrink some ( wineWine and winehasBody value wineFull ) OPTIONAL mealCourse rdfslabel label FILTER ( mealCourse = owlNothing )ORDER BY rdfslabel
Terp Grammar
bull Merge SPARQL grammar with Manchester syntax grammar
bull Keep all the syntax features of SPARQL
bull A few cases where ambiguity arises
bull Ex Parentheses are used for lists in SPARQL and for nesting in Manchester syntax
bull Try to resolve ambiguity by the context
bull Assume SPARQL intent otherwise
Implementation
bull Terp parser implemented in Pellet and available as of version 21
bull Integrated through Jena ARQ architecture
bull Can translate any Terp query to regular SPARQL syntax
bull Can be used programmatically or through CLI
Possible Extensions
bull Allow Manchester syntax in predicate position
bull Ex Use equivalentTo instead of owlequivalentClass and owlequivalentProperty
bull Support for additional OWL 2 constructs
bull Ex Negative property assertions axiom annotations
bull More syntactic sugar for frequently used OWL features

bull Use Manchester syntax for expressing class property or datatype expressions
bull Manchester syntax expressions can appear in subject or object position of triples
SELECT wine flavor wine a ( wineWine and winemadeFromGrape min 2 )
Complex Terp Example
bull Query Find meal courses that go with full-bodied wines if exists return the associated label order results by labels but donrsquot include owlNothingSELECT wine flavor mealCourse rdfssubClassOf foodMealCourse foodhasDrink some ( wineWine and winehasBody value wineFull ) OPTIONAL mealCourse rdfslabel label FILTER ( mealCourse = owlNothing )ORDER BY rdfslabel
Terp Grammar
bull Merge SPARQL grammar with Manchester syntax grammar
bull Keep all the syntax features of SPARQL
bull A few cases where ambiguity arises
bull Ex Parentheses are used for lists in SPARQL and for nesting in Manchester syntax
bull Try to resolve ambiguity by the context
bull Assume SPARQL intent otherwise
Implementation
bull Terp parser implemented in Pellet and available as of version 21
bull Integrated through Jena ARQ architecture
bull Can translate any Terp query to regular SPARQL syntax
bull Can be used programmatically or through CLI
Possible Extensions
bull Allow Manchester syntax in predicate position
bull Ex Use equivalentTo instead of owlequivalentClass and owlequivalentProperty
bull Support for additional OWL 2 constructs
bull Ex Negative property assertions axiom annotations
bull More syntactic sugar for frequently used OWL features
