How did this all start? Why only these three MLSs?

WIREX is the result of an invitation made by the South Central Wisconsin MLS to MLS, Inc and the RANW MLS to engage in a discussion to explore the possibility of sharing data.  These three MLS’s represent the three largest databases, and each one uses a different software provider.  It was believed that if they could create the technology to merge their data, then it would be easier to add others in the future.  The interest was to go beyond existing reciprocal access agreements and make the data more useful to brokers in their business’.
