"A variable is a parameter with a value that originates from the non-parametric description, e.g. properties of a parametric product or geometry description. Depending on the relation between a constraint and variable, the variable value may be changed by the constraint solution or has to be treated as a fixed value, similar to a constant value." .

"The represents individual property creates a link between a variable and the individual of the non-parametric description, e.g. a product or geometry description, that is the domain of the variable's considered property. Together with the represents individual property, the represents property property can be used in a SPARQL query to extract the given value that is represented by the variable, which serves as a default value, in case the variable is adjustable." .

"The has complex constraint definition property attaches an RDF-based constraint definition to a constraint node, e.g. in form of a formal definition of allowable value combinations or a technical definition of a mathematical equation/inequation. Due to the property's generic nature, the property may range to any RDF-based description for constraints. Since a constraint represents exactly one situation, this property is modelled to be inverse functional." .

"The OPS serves as a connector ontology for parametric systems. To obtain the flexibility to chose how the parametric constraints are described, the OPS does not consider the definition of constraints, but suggests to link to RDF-based or non-RDF constraint descriptions. To allow the evaluation of parametric systems in accordance to the Constraint Satisfaction Problem (CSP) approach, the OPS introduces concepts for variables, variable boundaries and systems of constraints that have to hold true at the same time.\r\n\r\n This work is part of the research project Semantic Construction Project Engineering (www.projekt-bpo.de), founded by the German Federal Ministry for Economic Affairs and Energy (BMWi)."@en .
