Data Will Now Cross The Trestle

Trestle by CoreLogic has been a sprint for the nation’s largest technology provider. On the heals of migrating more than 50 MLSs over to Matrix over the past 30 months, they had the added challenge of getting all of their MLS clients to be RESO certified (RESO = Real Estate Standards Organization). CoreLogic got them there, but at the Silver level of certification (Booooooo!). In a press release today, RESO has upgraded their certification on Trestle to Gold (Yeaaaaaa!) Why Trestle? Every MLS system vendor offers a server for publishing IDX and VOW data to enable brokers to hydrate their applications with MLS data. 100% of MLSs have these servers in place today and that is how vendors access MLS data. Application vendors who only serve customers in a single market tie to a single MLS live a peaceful life. However, when a broker or a vendor is connecting to more than one market, things get more complicated. Data Structure is different; field names are different; business rules for listing display are different; and so on. To compensate for the differences, major data aggregators like Wolfnet,, and Xome have developed processes for pulling data from all 700 or so MLSs, normalizing it to a single standard, and supplying it to their broker and agent clients. These companies are the big guys with over 90% of MLS coverage. All other vendors do smaller groups of MLSs that varies from 2 to more than a few hundred. Guess what. Pulling data from over 700 servers with more than 2 million listing updates is not the only hard part in this system. The other hard part is the IDX agreements. The big companies like Wolfnet,, and Xome have automated their IDX application process whereby the vendor, the broker, and the agent need to complete and sign a form. Xome’s RE Data Vault™ solution is also available to MLSs who are challenged with the document management headaches of managing all of the agreements. Imagine the paperwork of a large MLS with 30,000 subscribers, 500 vendors, and each subscriber having 3 data driven software applications. Yup – over 100,000 documents that need to be managed and signed. Trestle Does a Lot of Things to Fix All of This Vendors have a single place to access data from over 60 MLSs. Over 40 more have signed agreements eclipsing the market coverage area beyond 100. […]

It is RESO week. The week when CIO and CTO types gather together in Austin, TX for the Annual Real Estate Standards Organization meeting. This year’s conference was sold out for the first time with a rumored count of more than 700 participants. Kevin Hawkins of WAV Group Communications says that the environment and buzz at the conference is amazing. You can follow Kevin’s RESO updates on Twitter @RESO_RETS  or follow the RESO hashtag at #reso15 to listen to the conference chatter. One of the astonishing calls that I got today was from an MLS asking me if CoreLogic was providing their new RESO compliant/certified Trestle solution to non-corelogic MLSs for free. The Answer is YES! We verified that Black Knight Paragon customer Coastal Carolina MLS is going through the certification process on the Trestle RETS platform from Corelogic. WAV Group’s understanding is that Black Knight and other MLS system vendors may be charging a reasonable one time fee for their customers to update their RETS servers and go through the certification process. We did not check with every MLS vendor to find out the policy. We have learned over time that these types of fees are often calculated on a market by market basis anyway. CoreLogic is not charging any fees for compliance at this time. Brokers and technology vendors who rely on RETS have long been frustrated by the lack of a single standard and a RESTful API for too long. The National Association of REALTORS MLS policy committee made the RESO standard a requirement for NAR-affiliated MLSs over 16 months ago. The deadline for meeting that requirement is December 31st of this year. The requirement to provide the RESTful API is July. This is a huge endeavor for every one of the 770 MLS in America today. RESO has not announced how many are certified. WAV Group has watched for the announcements and it seems like about 50 to 100 have gone through the process. There are only 60 days left for MLSs to get certified! In truth, every vendor of MLS services is involved in RESO and it is not unreasonable for a vendor to charge a fee for the service. It is a major undertaking. The biggest challenge is that the MLS must fill out the paperwork and pay the RESO application fee before the vendor can do anything to update the system in time for the […]

MLSs and their vendors are staring down the barrel of the NAR requirement to become compliant with the RESO RETS Standard. Only 4 MLSs are currently certified, 764 to go. It’s really a double barrel, as MLSs are also adjusting to Listhub’s loss of syndication service to some leading portals. MLS vendors like Corelogic, FlexMLS, Rapattoni, Black Knight Financial, and the others are head-down developing solutions and launch plans to help their clients meet the December 31st, 2015 deadline – looming a short 6 months away. The deadline has created an eerie silence that makes me wonder how many MLSs will miss the date. The bigger question is what the NAR will do about it. According to CoreLogic customers, their vendor is launching a product called Trestle to serve the needs for RETS 1.3 compliance – but also extend the functionality of their RETS server by incorporating a dashboard empowering each MLS with an easy, self-managed distribution alternative to Listhub (from MOVE) or reDataVault (from RED) or Direct Syndication Platform (from Bridge Interactive). Best part – CoreLogic clients indicate that there will be no charges to the MLS for core services that replicate existing RETS. Part two of the RESO RETS Certification process is the delivery of a WEB API by the middle of 2016. Again, Trestle will deliver that requirement too. The announcement of this launch is timely. It looks to me like CoreLogic also plans to make a single API available to vendors for all MLSs that have valid MLS data licenses in place. That will solve many problems for application vendors like IDX service providers who would otherwise need to interface with multiple web APIs. In addition to the MLS data, for an additional fee CoreLogic plans to provide consolidated access to data sets normally found in REALIST including public records, property data, geographic overlays, AVMs, etc. CoreLogic’s strategy looks well thought out. It seems to encompass many strategies that other MLS vendors plan to deliver. It feels a little bit like a mash up of the best processes. I know that their customers are breathing a sigh of relief. Brokers, vendors, and MLSs should reach out to CoreLogic and other vendors to understand their plans. The landscape of data distribution in our industry is about to shift in a significant way.
