Data Dictionary Purpose
As RESO standards have grown, a common ground for fields and enumerations has been established. Keeping a centralized method of expressing property and listing concepts will mitigate implementation errors, ease field mapping and foster innovation around a more stable and cost-effective center. These benefits can be achieved by implementing the RESO Data Dictionary into services.
Through this international data standard, technological interoperability for real estate services and input forms is achievable. As real estate listings move from local systems to IDX, VOW and other approved systems, the Data Dictionary helps to ensure that the meaning of the data is not diluted or misinterpreted. When MLS subscribers see the same names and terminology around the data in external services, it creates consistency for both subscribers and their clients that see MLS reports and displays.
Wiki Tree Structure
The Data Dictionary Wiki is built on a tree structure with a traditional expandable/collapsible tree paradigm in the left navigation panel.
There are extensive links and cross links within the Data Dictionary wiki. For example, while viewing a Field with Lookups, you can also expand Lookup details. It is also possible to chain backwards from any Lookup items to one of its referenced Fields.
The RESO Data Dictionary is designed to grow with the real estate industry. New ideas are welcome. Change ideas require the following accompanying information:
Thank you for your interest and participation in the RESO Data Dictionary. All MLSs are invited to refer to the Data Dictionary as a future center for their own metadata (field/enumeration) change decisions.
Please send questions and/or suggestions to RESO at firstname.lastname@example.org. If you want to be part of the real estate data conversation, please join our growing ranks as a RESO member. Membership includes free certification.
