HEP Software Foundation Community White Paper Working Group -- Data Organization, Management and Access (DOMA) Open
Without significant changes to data organization, management, and access (DOMA), HEP experiments will find scientific output limited by how fast data can be accessed and digested by computational resources. In this white paper we discuss c…
