Editing Multiple listing service (section)

==Origin==
According to the U.S. [[National Association of Realtors]]:
<blockquote>In the late 1800s, real estate brokers regularly gathered at the offices of their local associations to share information about properties they were trying to sell. They agreed to compensate other brokers who helped sell those properties, and the first MLS was born, based on a fundamental principle that's unique to organized real estate: Help me sell my inventory and I'll help you sell yours.<ref>{{cite web|url=https://www.nar.realtor/topics/nar-doj-settlement/multiple-listing-service-mls-what-is-it/|title=What is a Multiple Listing Service (MLS)?|date=11 January 2012 |access-date=20 March 2017}}</ref></blockquote>

The term "MLS" is considered generic in the United States and cannot be trademarked or branded. MLSs can be owned and operated by individual realtor associations, regional multi-association conglomerates or independent cooperatives of real estate brokerages. There is no single authoritative MLS. However, there is a data standard for MLS systems. The ''Real Estate Standards Organization'' provides the Data Dictionary<ref>{{Cite web|title=Data Dictionary|url=https://www.reso.org/data-dictionary/|access-date=2020-10-10|website=RESO - Real Estate Standards Organization|language=en-US}}</ref> for common real estate terms and data structures, and the RESO Web API<ref>{{Cite web|title=RESO Web API|url=https://www.reso.org/reso-web-api/|access-date=2020-10-10|website=RESO - Real Estate Standards Organization|language=en-US}}</ref> for data transport. A previous common data transport standard, [[Real Estate Transaction Standard|RETS]], has been deprecated.
