The GDD: standardising real estate language worldwide

Did you know the Global Definitions Database (GDD) is the most visited page on INREV’s website each year? It’s easy to see why. The GDD provides a common glossary of non-listed real estate terms, helping investors, managers and service providers speak the same language across regions and products.

Many definitions in the GDD have been agreed upon globally, ensuring a shared understanding for key concepts such as performance metrics, reporting standards and valuation practices. Others are tailored to regional standards and data products, with terms specific to Asia, Europe and North America, reflecting local market practices while maintaining global comparability.

The GDD is a living resource, evolving as the industry does. So far in 2025, we’ve added six definitions under the theme ‘Journey of the Capital’ and 5 new ones under debt and capital activity. These additions aim to provide clarity on emerging topics and practices in fund and asset management, supporting both investors and managers in navigating complex structures. 

By offering a standardised reference point, the GDD helps reduce misinterpretation, increases efficiency and enhances transparency across the global non-listed real estate market. Whether you’re evaluating investment reports, preparing disclosures, or comparing regional practices, the GDD is an essential tool to ensure everyone is aligned.
