I plan to show a general construction of C*-algebras, starting from a semi-groupoid, which was motivated by Kumjian and Pask's recent study of higher-rank graph C*-algebras. Along the way I plan to discuss the notion of tight-representations on inverse-semigroups, which is the cornerstone of this method.
