# Commons Commons are created through the combination of a service connection (the means to connect) and the data-sharing agreements (the contract between data-provider and data-consumer). Before a data-consumer is able to access the common, it is necessary to accept the data-sharing agreement attached by the data-provider. The operations allowed in a common are explicitly defined in the data-sharing agreement and they include the possibility to: read, execute scripts and combine data from it and other sources. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.trustrelay.io/elements/commons.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
