Data shares are common in the industry, especially among neighboring MLS markets.
Providers that implement data shares should be sure to include the relevant originating and source system information so end users can filter and differentiate between listings in various markets.
Each Data Dictionary resource has the following fields:
- OriginatingSystemID – the unique ID of the system where the record originated
- OriginatingSystemName – the unique name of the system where the record originated, commonly the name of the MLS where the record was entered
- SourceSystemID – the unique ID of the system where the record was obtained from,usually the ID of the system hosting the record
- SourceSystemName – the name of the system hosting the record
Example
Assume that there is a data share between MLS A and MLS B. The OriginatingSystemName of records created in A or B could be “MLS A” and “MLS B,” respectively.
OriginatingSystemName is the most commonly used field to indicate which system a record was entered in. End users should be prepared to support this field to differentiate where records originate from, but also OriginatingSystemID in cases where it is used instead.
