    Key RESO Standards for Real Estate Professionals

    In the wide-ranging real estate industry, RESO standards serve as markers that improve the sharing of information and collaboration among real estate professionals. Among these standards, two stand out for their vital role in shaping the industry - the RESO Data Dictionary and the RESO Transport Standards.

    The RESO Data Dictionary is the universal language for real estate data, ensuring that different systems can communicate effortlessly.

    Imagine a world where every real estate professional speaks the same language. No confusion, no misinterpretation – just seamless communication. That’s what the RESO Data Dictionary brings to the table. It serves as the universal language for real estate data, ensuring effortless communication between various systems.

    By standardizing the structure and content of property listing data, the RESO Data Dictionary ensures consistency across the many MLS databases, simplifies integration for various tools, and contributes to the creation of more insightful property data. It defines fields and resources such as:

    • ‘PropertyType Field’
    • ‘ListingStatus Field’
    • ‘Price Field’
    • ‘Bedrooms Field’
    • ‘Bathrooms Field’

    The RESO Data Dictionary also allows for the establishment of custom fields to cater to unique local market situations while maintaining interoperability.

    RESO Transport Standards

    The RESO Transport Standards are the main routes for data movement in the real estate sector. They allow for the easy transfer of listing information between different apps, servers, and systems within the industry, ensuring that data can travel smoothly and efficiently.

    A main objective of the RESO Transport Standards is to enable real-time retrieval of MLS data via standard search methods in the format designed in the RESO Data Dictionary. They provide a consistent approach for technology partners to follow across markets, while also allowing them to extend the standard with their own unique features.

    The Role of RESO Web API

    What the RESO Web API aims to achieve in the real estate industry? It standardizes data formatting and transmission, making information exchange as effortless as a walk in the park.

    The RESO Web API is:

    • The organizer of real estate data.
    • Promoting standardization across different real estate systems
    • Enabling compatibility and more seamless data sharing between MLSs, brokerages, and other real estate platforms.

    Importance of RESO Web API

    The RESO Web API significantly enhances real-time access to MLS databases, independent of websites and applications, in the real estate sector. It simplifies the data transfer process to IDX websites, addressing the limitations of the older RETS standard by negating the need for developers to individually copy and update MLS databases.

    Leading MLSs are increasingly moving their customers to Web API services exclusively, encouraging businesses to use certified data systems to take full advantage of RESO standards and analytics. Indeed, the RESO Web API has emerged as the interface for application and server interactions.
