CoreLogic® has officially received RESO (Real Estate Standards Organization) vendor certification for the latest version 2.0 of the RESO Data Dictionary and will be collaborating with individual multiple listing organizations on their certification in the weeks to come.
Why RESO Data Dictionary v2.0 is a Big Deal
The RESO Data Dictionary 2.0 brings significant improvements to how real estate data is standardized and shared. It ensures all data elements are clearly defined and consistently represented, providing multiple listing organizations and their partners with higher-quality, reliable data. Data licensees can expect increased predictability and consistency since records are tested against the schema.
The best thing about the Data Dictionary 2.0 release is how easy Trestle™ by CoreLogic will make it for multiple listing organizations and their data licensees to make the transition.
How Trestle Makes the Transition Easier
Trestle, CoreLogic’s data distribution platform, makes it simple for multiple listing organizations and their data partners to migrate to RESO Data Dictionary 2.0 without disruption. Here’s how:
- Flexible Data Options: Trestle allows multiple listing organizations to set up feeds for Data Dictionary 2.0, migrating from the older version, while also allowing MLSs to offer 1.7 with “Trestle Direct” to Matrix. This enables organizations to better support products that want to utilize local-specific data and enumerations, improving subscriber adoption and decreasing subscriber questions that occur when translating local fields and enumerations to standard ones. This is ONLY available with Trestle Direct from CoreLogic.
- Most Comprehensive Schema: The Trestle Dictionary 2.0 schema includes more fields and enumerations than any other data distribution server:
- 1,750+ RESO 2.0 fields
- 82,000+ enumerations (lookup values)
This provides the best foundation for large data shares and makes it easier to aggregate data between several multiple listing organizations. Trestle contains more than 210 million properties and 2.1 billion media.
- Web API or RETS: Trestle supports both Web API and RETS feeds, giving multiple listing organizations and technology providers the flexibility to choose the best option for their needs.
Introducing UPI Version 2.0
Another game-changing feature of the new RESO standards is the Universal Parcel Identifier (UPI). Traditionally, property data has been inconsistent due to varying address formats or parcel numbers. The UPI simplifies this by providing a unique, standardized identifier for each property, making it easier for data consumers to match property records across many multiple listing organizations.
CoreLogic is leading the way by being the first multiple listing data distributor certified on UPI version 2.0. With the UPI integrated into new property listings, data consumers can more easily track, group, and de-duplicate property information across different multiple listing organizations, improving accuracy and efficiency.
Do Even MORE With CLIP
CoreLogic also offers CLIP™, a unique identifier that links all instances of that property across our data sets. By linking records, CLIP delivers an accurate view of any property, even ones that have yet to enter tax-roll records. CLIP’s data connectivity creates, enriches, and enhances property data aggregation, delivering more high-quality and useful details than any single data set.
Moving Forward with Confidence
CoreLogic is proud to be at the forefront of real estate data innovation. With RESO Data Dictionary v2.0 certification and UPI implementation, we’re not just improving data quality—we’re paving the way for a more streamlined, efficient, and standardized real estate industry.
In addition to upholding the latest data standards, Trestle also takes the work and worry out of data licensing.
