Mandatory fields are marked with *

• Access Type*

  An asset can be a downloadable file or a compute service on which buyers can run their algorithm. By selecting download, buyers will be able to download the dataset. Select compute if the access to the dataset is to be allowed in a compute-to-data environment.
