What is IDX (Internet Data Exchange)?
From Wikipedia, the free encyclopedia
An Internet Data Exchange (IDX) is a real estate property search site which
allows the public to conduct searches of approved Multiple Listing Service
properties in a certain area.
Site users generally gain the benefit of anonymous property searching and
review. IDX sites usually provide less detailed information than the full
Realtor Multiple Listing Service, limiting the data to that which is deemed
publicly accessible. The benefit to realtors is that users of their IDX web site
can search freely, establish some confidence, and qualify themselves before
contacting the realtor.
Certain rules apply to the real estate companies' ability to display each detail
about a property. These "display rules" are set by the Multiple Listing Service
organization, which generally forms its policy around the recommendations of the
National Association of Realtors.
IDX policy is nearing its replacement by a new Internet Listing Display policy
being formed by the National Association of Realtors.
A common and standard data exchange protocol for IDX information is the Real
Estate Transaction Specification or RETS.
