Seed Potato Classification Scheme

"The Seed Potato Classification Scheme (SPCS) provides classification of all potatoes produced and marketed in England and Wales, depending on the class of the parent seed, and the health of the crop and tubers. The aim of the SPCS is to provide assurance that seed potatoes delivered to buyers and growers meet specified minimum health and quality standards."

Semantic Web Rule Language

"This document contains a proposal for a Semantic Web Rule Language (SWRL) based on a combination of the OWL DL and OWL Lite sublanguages of the OWL Web Ontology Language with the Unary/Binary Datalog RuleML sublanguages of the Rule Markup Language. SWRL includes a high-level abstract syntax for Horn-like rules in both the OWL DL and OWL Lite sublanguages of OWL. A model-theoretic semantics is given to provide the formal meaning for OWL ontologies including rules written in this abstract syntax.
