These spaces are determined by fusion and linking systems over ``discrete $p$-toral groups'' --- extensions of $(\Z/p^\infty)^r$ by finite $p$-groups --- in the same way that classifying spaces of $p$-local finite groups as defined in \cite{BLO2} are determined by fusion and linking systems over finite $p$-groups. We call these structures ``$p$-local compact groups''.
