Next week, I will participate in the 2012 Noprofit Technology Conference Science Fair hosted in San Francisco.
Below is the exhibit board I developed for depicting and explaining Multiple Listing Service Network Protocol.

Above are my slides from last week's PRIA Winter Symposium 2012 hosted in Washington DC. The panel session's topic was on cloud computing and the property records industry. Enjoy and feel free to comment or ask questions.

To capture the essence of Real Estate and Computer Science in a logo, an icon was needed to mesh or connect the two knowledge areas together. In doing so, the above two-dimensional icon within the re-sci logo is a graph which simply represents a connected world. Using graph theory, ten nodes or vertices are connected by lines or edges. The nodes are colored blue and green to represent water and land, respectively, while the addition of edges create universally accepted home icons within the logo's icon.
Custom blue and green colors were chosen for the textual lettering to match the nodes' coloring. The font face used was PakType Tehree with a medium style. Inkscape was used to create the re-sci logo, .
Purposefully, multiple home icons can be found within the 2d graph icon. Just like a multiple listing service, this type of design was used to represent a global mls or a world wide mls. In future versions, the icon graph may become three-dimensional and much larger in scale.
At first glance, you may notice only two home icons within the icon graph, but if you look closely there are many more. Please feel free to comment below on how many hidden home icons you see located within the new re-sci icon graph. :)
The Real Estate Science logo can now be found on ResearchGate.net and on Twitter @rescience.

Last night, I submitted my abstract to the Red Hat JBoss Summit 2012 call for proposals. Below is my abstract:
A Nonprofit Case Study: OpenShift, JBoss, and Amazon Web Services
In the real estate industry, buyers and sellers are constantly researching listing property information such as status, price, and location. A Multiple Listing Service (MLS) is a localized database which association members, salespersons and broker salespersons, access to update their clients with relative property information. However, this process has become slow and outdated because of the Internet and the Web.
The Global Real Estate And Technology Consortium (GR8C) is a scientific nonprofit located in Orlando, Florida. Its mission is to promote the education, operation, and use of the World Wide Multiple Listing Service (WWMLS) to its fullest potential by developing protocols, specifications, and standards for the benefit of all people throughout the world.
This case study will provide a low-level look at the Multiple Listing Service Network Protocol (MLSN), a new request-response messaging protocol developed by the GR8C for querying property information on user reserved port 32801. The session will discuss how OpenShift is used to build, deploy, and monitor configured JBoss Application Servers as MLSN Servers to Amazon's Web Services Platform. In addition, the presenter will share key lessons learned and technical issues dealing with OpenShift. Finally, an MLSN client to MLSN server messaging demonstration will be provided.

Last Saturday marked the first birthday for the World Wide MLS (WWMLS). Since then, the follow progress has been made towards WWMLS:
As MLSN is presented to different groups such as academics and technologists, I am confident with the two upcoming presentations in 2012, especially in St. Petersburg at ARES, that the MLSN Protocol and WWMLS framework will alter others' thought processes of not only the dysfunctional aspect of today's legacy MLS, but also future directions in how real estate consumers interact and expect a specific quality of service (QoS) from real estate professionals. The main intention is integrate WWMLS in every aspect of the future of real estate.
Moving foward, the second phase for WWMLS will be the introduction of the messaging language called Real Estate Metadata Language (Remetal). This XML language will be used to markup properties in a self-describing, yet simple language for sending and receiving between the main OpenMLS Registry and accredited OpenMLS Registrars. I plan to propose Remetal to additional call for papers (CFP) on the academic and technical levels in 2012.
The third yet most important phase will be for the Real Estate Transport Protocol (RETP). This protocol defines the type of messaging, the distribution channels, error correction system, etc. Again, RETP papers will be proposed along with exhibitions at national and if necessary global science fairs.
The future of real estate is bright and changing.
And as the cliche goes, please stay tuned...

Today I submitted my abstract for the American Real Estate Society (ARES) conference in April next year:
Title: MLSN: A Request and Response Internet Protocol for Real Estate Property Listings
Abstract:
Sellers list their properties with real estate professionals who enter property information into private databases called Multiple Listing Services (MLS). These MLS's attempt to store and index data 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 MLS's 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 five to ten digits long or more relaying no meaningful or geographical information to real estate professionals, sellers, and buyers alike.
This paper proposes and discusses a new internet protocol called Multiple Listing Service Network (MLSN) Protocol for registering, assigning, and distributing property listings on the Internet. Similar to the WHOIS protocol, MLSN is an application publicly available on the Internet, however instead of port 43, MLSN is accessible from reserved 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 standardized by ISO 3166-1. Taking in consideration for expired listings, MLSN offers a reusable feature which allows assigning a new, double-dotted notation number to a preexisting triple-dotted number thereby creating a new MLSN property listing number. Together with a standard protocol and unique numbering schema, MLSN provides a uniform resource locator (URL) to users for conducting a more efficient and convenient real estate property searching on the Internet.

Falling under the real estate science's discipline umbrella is the World Wide MLS(tm). What exactly is the World Wide MLS(tm) you ask? The World Wide Multiple Listing System (WWMLS) is a global registry listings application layered, nice and neatly, on top of the Internet.
Using reserved ports 32801 and 32811, WWMLS will allow public access to registry listings to users and accredited OpenMLS(R) registrars. Somewhat like the WHOIS protocol, the Multiple Listing Service Network Protocol binds to port 32801 using tcp and udp. Users or registrars request a listing's information by sending a message to an MLSN server which returns listing information or a "no match" response.
The other half of WWMLS involves the Real Estate Transport Protocol (RETP). RETP distributes listings from registrar to registry to registrars. The messaging protocol uses reserved port 32811 and tcp only. In a later blog post, I will expound more on RETP, its workings and significance to the World Wide MLS(tm).
