{\it Section Status: draft in progress. 
To Do: 
Introduction to  {transient} science with   LSST  and the challenges posed.  
Brief outline of the   LSST  strategy - point to section \ref{sec:alertproduction}
Introduce the concept of Community Event Brokers.   
Describe the goals and format of the meeting including the unconference sessions. }

Following the January 2019 'Call for Letters of Intent for Community   Alert  Brokers'  
\citep{LDM-612}
the   LSST  Project hosted a workshop with the goal of bringing together representatives of all 

The workshop addressed several topics: 
\begin{itemize}
    \item Science Drivers (section \ref{sec:science}) --- what are the science drivers for Brokers?
    \item  {Broker} Architecture and Technology (section \ref{sec:archandtech}) --- what technology will underpin  {Broker} services 
    \item Algorithms \ref{sec:algorithms}) ---  what kinds of user algorithms do Brokers need to support 
    \item Follow-up infrastructure \ref{sec:followup}) --- how do Brokers interface to follow-up services 
    \item User-facing services \ref{sec:interfaces}) --- how will the scientific community interact with brokers 
\end{itemize}

This paper summarizes the presentations and discussions of the workshop. It highlights many ideas and recommendations that came out of the workshop. The workshop presentations are available at $<someurl>$ and we refer to them throughout this paper.


To address these challenges, we make the following recommendations
% A registry of brokers should be used to facilitate communications such as those
% outlined in ticket:
% DM-20561 Updates for communications with broker proposers (from CBW FAQ)
