content: Attributes, External Relations and Representations Form the Trichotomy The forthcoming release of KBpedia version 1.50 deals primarily with the addition of a relations schema to the knowledge structure. In the previous part of this series, I discussed the event-action model at the heart of the schema. Actions are external relations between two objects, including parts, for which we use the variable shorthand of A and B. In terms of the universal categories of Charles Sanders Peirce [1], these dyadic relations are a Secondness that we formally term External Relations, or A:B. But external relations do not constitute the complete family of relations. External relations are but one form of predicate we require. We need relations that cover the full range of language usage, as well as the entire scope of OWL properties. KBpedia is written in OWL2, which is the semantic ontology language extension of RDF. We need to capture the three types of properties in OWL2, namely object properties, datatype properties, and annotation properties. In Peircean terms, we thus need relations that characterize the subject itself (A:A), which are mostly datatype properties, as well as statements about the subject (re:A), which are annotation properties. Most external relations are represented by object properties in OWL2, but sometimes datatype properties are also used [2]. We call relations of subject characterizations Attributes, and these are a Firstness within Peirce's universal categories. We call relations about the subject Representations, and these are a Thirdness within the universal categories. The purpose of this part in our series is to introduce and define these three main branches of relations -- Attributes, External Relations, and Representations -- within the KBpedia schema. Nature of the Trichotomy In accordance with the design basis of KBpedia, we use Peirce's universal categories and his writings on logic and semiosis (signs) to provide the intellectual coherence for th…
