This project links Montreux Jazz audiovisual archive metadata with the Secure Open Platform developed by EPFL in collaboration with CHC, SDSC, and DCML. It builds on the Open Science project for secure computation, enhancing the platform with metadata for data subset selection. An SQLite database REST API will list concert information, enabling frontend search requests. A secure Custodian-compliant REST API will automate user authentication, data queries, and algorithm execution. This supports web apps, such as those developed at DCML, to log in, run authorized algorithms on selected data, and display results in the browser.
