The RESO Data Dictionary is designed to grow with the real estate industry. New ideas are welcome. Change ideas require the following accompanying information:
Name: Review existing fields or enumerations and create a name that fits the current convention.
Definition: Write a robust definition of your entry idea.
Data Type: Include your recommended data type and maximum field length.
Lookups/Enumerations: Include enumerations if your recommended field is a picklist. Enumerations will also need a robust definition.
Justification: Offer a meaningful reason that the field is important to your market. If the field has legal or MLS rules requirements, include a reference back to the law or rules in question.
Utilization: Include an indication of how frequently your field or enumeration is used as a count of total listings using the field or enumeration and the number of listings in your sample. From this, a percentage of utilization will be created. Include the criteria used to determine the sample of listings used.
Duplication: Review the Data Dictionary thoroughly to ensure that the new idea is not duplicating an existing field or enumeration. Rather than adding additional fields or enumerations, alternate names can be added to the Synonym column and/or used to improve a field's definition.
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/lookup) change decisions.
