MLSN Research Abstract

Next week, I will submit the following research abstract to the Graduate Research Forum at UCF. I am currently working on my Master's in Nonprofit Management in the College Public Administration. In addition to the abstract below, I will also follow up with a white paper explaining the Multiple Listing Service Network (MLSN) Protocol and system in detail.


Sellers list their properties with real estate professionals who enter property information into private databases called Multiple Listing Services (MLS). These MLSs attempt to index listings with serialized numbers that only members of the local real estate association have access to query, insert, and update. In the United States alone, there are over 900 MLSs which unfortunately create redundant, localized MLS numbers causing confusion over specific properties and their respective listing information on the Internet. These duplicated MLS numbers can be anywhere from eight digits or more relaying no meaningful or geographical information to real estate professionals and real estate buyers alike.

In this paper I introduce a public, standardized numbering system and protocol called Multiple Listing Service Network (MLSN). Similar to the Web, MLSN is an application publicly available on the Internet, but instead of port 80, MLSN is accessible from port 32801. The numbering scheme is comprised of two parts separated by an '@' symbol: (1) a triple-dotted notation of three decimal integers ranging from 1 to 65,535 and (2) a double-dotted notation number composed of a postal code and country code defined by ISO 3166-1. Taking in consideration for expired listings, MLSN numbers have a reusable feature which allows assigning a new, double-dotted notation number to a preexisting triple-dotted number thereby creating a new MLSN number. Together with a standard protocol and unique numbering schema, a Uniform Resource Locator (URL) is available to users for searching for property listings on the Internet.
