Real Estate Data Standards
Our data collection and interpretation methodology
Our commitment
We follow a standards-based, best-practice approach to organizing real estate information: consistent meanings, clear units, retained source documents, and contributor review. Our goal is to make each listing easier for people and AI assistants to read, compare and understand.
1. A common language for property information
The Real Estate Standards Organization (RESO) maintains the Data Dictionary: shared definitions for real estate fields, their formats and permitted values. It helps different systems describe property information consistently. Read RESO’s overview.
ListViaAI uses selected definitions from Data Dictionary 2.1 as its reference. For example, price, living area, lot size and bathroom counts have distinct meanings; a number should retain the units and context needed to understand it. Any additional ListViaAI fields remain separate from the official standard.
2. How we collect and organize listing details
- Read the source. Contributors upload a listing-sheet PDF or photos of its pages, or enter details themselves. Uploaded originals are retained privately for later reference.
- Put details in the right fields. Our AI interprets public listing information using the field definitions. Missing or unclear information should not be filled with invented facts.
- Ask when something is unclear. Listing sheets use different labels and formats. Meaningful conflicts are offered for optional clarification; routine missing optional details are not a correction checklist.
- Let the contributor decide. Contributors can edit details or confirm that they are correct before making their listing available. Unresolved information may carry an “Awaiting review” note.
- Share the approved listing. Public listing details, selected property photos and chosen contact information are shared. The original listing sheet and internal review notes stay private.
3. Why this helps people and AI assistants
A consistent format reduces the need to interpret unfamiliar abbreviations or guess what a number means. We use that consistency to help buyers and their AI assistants find and evaluate relevant facts more easily. Standards improve organization; they do not guarantee that an AI service will discover a listing or interpret every detail correctly.
4. Accuracy and contributor control
A well-organized listing does not have to be perfect to be useful. Contributors can skip optional corrections and return later. AI interpretation can make mistakes, and this process is not an inspection or independent verification of the property. Buyers must conduct their own due diligence.
