This report is based primarily on a workshop involving 42 people from academia and industry.
The goal of the workshop was to share systematic knowledge about the components, characteristics,
practices, and transformative impact of effective VOs; identify topics for future research that will
inform the ongoing design, development, and analysis of VOs for science and engineering research
and education; and create a new cross-disciplinary VO research community to conduct research across
a range of important topics. A subsequent workshop brought together more than 200 practitioners and
VO researchers to discuss how to build effective virtual organizations, and some of the material from
that workshop is represented here.
