When reusing data provided by data holders, public sector bodies, the Commission, the European Central Bank or Union bodies should respect both existing applicable Union or national law and contractual obligations to which the data holder is subject. They should refrain from developing or enhancing a connected product or related service that compete with the connected product or related service of the data holder as well as from sharing the data with a third party for those purposes. They should likewise provide public acknowledgement to the data holders upon their request and should be responsible for maintaining the security of the data received. Where the disclosure of trade secrets of the data holder to public sector bodies, the Commission, the European Central Bank or Union bodies is strictly necessary to fulfil the purpose for which the data has been requested, confidentiality of such disclosure should be guaranteed prior to the disclosure of data.
