RETS (Real Estate Transaction Standard) is the open standard for exchanging real estate transaction information implemented by The National Association of REALTORS® (NAR). Consisting of a transaction specification and a standard Extensible Markup Language (XML) Document Type Definition (DTD), RETS is being implemented by many real estate industry leaders in their next generation of real estate information systems.

What is Standard?

In the software industry, there are not programs themselves, but rather a set of rules that independent developers can follow when creating software that will work together with other software built using those same rules. They do not define what the program should do, only that it adheres to specific standards.

MRIS complies with the new software standard recently developed by the NAR as well as the RETS standard. For years, the real estate industry has dealt with multiple software standards. RETS incorporate XML (eXtensible Mark-Up Language) technology, a new Internet language that is more flexible than today’s current standard, HTML. RETS will allow different software programs to more easily interact with one another.

By ensuring it is compliant with this new standard, MRIS is prepared for changes the real estate industry will experience in the coming years. Just as the Internet drastically affected the industry, these new standards will also have a major impact.

How Can MRIS Customers Use RETS?

Customers may use RETS in a number of different ways. They may use it if they buy software or services from a company who uses the RETS system to access MRIS data. RETS is used to transport data to Web site operators such as broker company Web sites or licensed Web site vendors. RETS is also used to send data to service providers that sell services to our agents such as Supra for lockbox services and ShowingTime or Centralized Showing Service for appointment scheduling. RETS also allows third party software developers to gain secured access to the system, such as GoHome for their ActiveAgent product.
