Abbreviation: SchrCat
A \emph{Schroeder category} is an enriched category C=⟨C,∘,dom,cod⟩
in which every hom-set is a Boolean algebras.
Let C and D be Schroeder categories. A morphism from C to D is a function h:C→D that is a \emph{functor}: h(x∘y)=h(x)∘h(y), h(dom(x))=dom(h(x)) and h(cod(x))=cod(h(x)).
Remark: These categories are also called \emph{groupoids}.
