On-Demand Distributed Computing Workflow for Physics Analysis at the CMS Experiment*

The CMS experiment is a strong contributor to the CERN Open Data Portal. CMS Open Data project releases data collected from proton-proton collisions at the LHC to the public. It publishes research level data together with the environment, software and instructions. These data can be used by the scientific community and the general public for physics analysis. This talk will describe the development and tests of simplified examples for the use of open data, analysis preservation and a new reproducible research data analysis platform.
