Open Property Data Associationgeneral
Different property professions add distinct evidence pieces to a shared layered model of one property.

Your experience can improve property information

The Open Property Data Association (OPDA) is inviting people with experience across the property journey to help develop the Smart Property Data Trust Framework. The working groups are developing shared definitions for property information so that people can understand and exchange it more clearly.

Why it matters

A property transaction brings together information from many organisations. Repeated questions and differences in meaning make that information harder to use.

Where your experience helps

Help explain what information means in your work, which exceptions matter and what other people need to understand when you share it.

  • Explain meanings, rules and exceptions.
  • Review draft definitions and proposals.
  • Bring examples you are authorised to share.

Who can contribute

You do not need data-modelling expertise. Your professional experience and judgement can help shape the work.

Professional, commercial and public-interest perspectives all matter. Choose the group closest to your experience.

What happens next

Registering is an expression of interest. OPDA reviews each submission and confirms the next steps. It does not automatically give membership or access.
