Carolina Data Share (CDS)

What is Carolina Data Share?
Carolina Data Share (CDS) is a cooperative effort of multiple listing service (MLS) organizations to share listing data for advertising display on the Internet.

Since 2001, each MLS has independently offered its own brokers the ability to display on the Internet MLS active-listing information through a program called Internet Data Exchange (IDX). Through IDX, brokers permit other brokers to advertise their active listings on one another’s Web sites. Brokers may include their listings in the IDX database without having their own Web sites.

CDS is an expansion of the IDX program. Any Participant or Subscriber in any participating MLS can display IDX data from all CDS participating MLSs on their Web site.

Brokers who participate in CDS can have Web sites with the most comprehensive selection of active real-estate listing information, and their listings are exposed on the Web sites of other brokers. Buyers benefit because when visiting the Web site of any participating broker, buyers have access to nearly 99 percent of the active listings of the participating MLSs. Sellers benefit, as well. Unless a broker or seller opts out of the program, his or her listings appear on the Web sites of thousands of brokers and agents.

Broker Web sites can effectively compete with Web sites of national aggregators as comprehensive sources of listing information.
