Abstract

This paper examines Jewish dietary laws (kashruth) as a knowl­edge domain, focusing on the ways tacit knowl­edge has impacted the development and continued use of this dietary ontology. Building from this case study, a framework is proposed for categorizing tacit expressions and assessing their impact on knowl­edge organization practices. This framework establishes three tacit categories based on two communicative variables – self-disclosure and verbal omission – and emphasizes the methodological value of a domain-analytic approach for identifying tacit traces within explicit language.
