Google Adds New Optional Property IsAccessibleForFree To The Dataset Documentation
https://developers.google.comGoogle has updated the Dataset Structured Data to add a new optional Boolean property (can be set to true or false) called IsAccessibleForFree. When set to true it means that the dataset is accessible for free.
The purpose of this Dataset markup is to improve the discovery of datasets from fields such as life sciences, social sciences, machine learning, civic and government data, and more. You can use Google’s DataSet search tool to quickly search for data sets. The new property will make it easier to discover free data sets.
