The HEP Analysis Software Ecosystem workshop will take place from 22-24 May, 2017, at the EYE Film Museum in Amsterdam, the Netherlands. The workshop is being organised by the HEP Software Foundation (HSF), the Dutch National Institute for Subatomic Physics (Nikhef) and the DIANA/HEP project. The workshop is being convened by the HSF to examine the HEP analysis software ecosystem, both today and with a 5-10 year view.

Over the past 20 years the HEP community has developed and gravitated around an analysis ecosystem centered on the ROOT software toolkit. ROOT and its ecosystem dominate the HEP data analysis environment. The broader data science landscape is however evolving in ways that can have a durable impact on the HEP analysis ecosystem over the next decade, a timescale currently in an intensive planning round with the HEP Software Foundation (HSF) Community White Paper process. Data intensive analysis is growing in importance in other sciences and in the wider world. Powerful tools and new development initiatives, both within the field of HEP and in the wider open source community, have emerged. The workshop will take stock of the landscape and discuss ideas for how the HEP analysis software ecosystem could evolve.
