Once the relevant open data standards have been identified, the next step would be to develop a data sharing framework that outlines how the data will be shared and used within the platform. This framework could specify the data formats, protocols, and other technical details that will be used to ensure that the data is shared and accessed in a consistent and interoperable manner. The framework could also include guidelines and best practices for users of the platform, to help them understand how to share and use the data effectively.
