The High Energy Physics (HEP) Software & Computing Knowledge Base at hepsoftware.org is a collection point for HEP related software projects and information on HEP software and computing. Its development was one of the earliest priorities of the HEP Software Foundation (HSF). It catalogues existing software, provides visibility and discoverability for new and emerging projects seeking collaborators, and disseminates knowledge on who is using what.
The foremost objective is to reimagine and reimplement (creatively, with plenty of room for improvement) hepsoftware.org with at least the feature set of the present version.
Further objectives for a particularly productive developer could be adding un-implemented functionality, such as
A new production capable implementation of hepsoftware.org, ideally with an expanded feature set, fully open source and maintainable by the HSF with the ongoing participation of the GSoC developer should they choose.
