##### Title

The Raeburn-Taylor algebra revisited

##### Abstract

Given a 2-cocycle $c$ with values in the sheaf of continuous $\mathbb{T}$-valued functions relative to an open covering of a locally compact Hausdorff space $X$, Iain Raeburn and Joe Taylor constructed a continuous trace C*-algebra $A$ with primitive ideal spectrum $X$ and Dixmier-Douady invariant determined by the class of $c$. We review their construction in a groupoid friendly way.
