Hubs ‘ Я Us hubzero.org • Feb 2007: 1 hub • Feb 2008: 5 hubs • Feb 2009: 8 hubs • Feb 2010: 21 hubs Each hub has its own funding stream HUBzero: an organization with Recharge Center
HUBzero Consortium hubzero.org • Four founding members • Ongoing development of HUBzero core • Documentation: http://hubzero.org/documentation • Dissemination and support, yearly conference
Recent Workshop University Place Conference Center April 13-14, 2010 Indianapolis, IN Open Source Release! Tutorial Tracks: • Setting up a new hub • Managing hub content • Creating and publishing scientific tools • Extending hub functionality through PHP/web programming http://hubzero.org/hubbub2010 http://hubzero.org/hubbub2010
HUBzero™ Roadmap and Community Feedback George Adams and Michael McLennan HUBzero Consortium 10
Grand Challenges Feedback from Challenges: Dealing with large data sets, our survey usability, visualization Federated access to the hub so I can integrate a variety of web resources and so my users can seamlessly access resources in multiple security domains. Creating the tools to enable community authoring of content to share between teachers, as well as enabling and enforcing the proper relationships and data privacy for teacher/student and teacher/class relationships. Elevate computing and software development to the same level of reproducibility and peer review as traditional publishing. 11
