The Non-Negotiables:
True Interoperability
True “choice” requires creating listings from anywhere - it’s not enough to simply view and edit from multiple front-end.
Granular Data Control
The MLS needs to be able to make data dictionary updates and schedule new changes without having to ask vendors for permission.
RESO-Based Architecture
Architected from the beginning along the RESO-standards and scalable to support future certifications.
Independent Database
A centralized database independent from any one MLS front-end vendor gives the MLS full control and decreases its dependencies.
Business Rule Validation
Business rules need to be unified between each front-end listing input interface participating in order to ensure clean and uniform data.
Support for Local Fields
A solution must be versatile enough to support local fields from the participating MLS systems to fully facilitate interoperability.
Beyond Listing Data
Scaling beyond listing and property data allows MLSs and their partners to integrate an expanding array of data sources.
Bulletproof Security
State-of-the-art security and encryption best-practices maintains operational integrity and eliminates the risk of data disruptions.
Marketplace Creation
The system must be able to generate a revenue stream through direct dissemination of data feeds to create shareholder value.

Unlock The Power of Your MLS Database
For years, MLSs have outsourced the stewardship of their data to the organizations that manage their front-end member software, resulting in an inherently restrictive and sluggish technology environment.
