What is RETS?

edit

The Real Estate Transaction Standard (RETS) is a specification for a standard communication method between computer systems exchanging real estate information. It defines a standard interface for use by applications such as agent desktop software, IDX (Internet Data Exchange) systems, data aggregation systems, and many other systems that store, display or operate on real estate listing, sales and other data.

Or to put it more simply: it is the agreed upon “rules of the road” for data transfer in the Real Estate market.
