1. Grid categorisation (Cluster Grids, Collaboration Grids and Data Centre Grids):

The categories Cluster and Data Centre Grids appear to relate more to a way that the resources are organised while the 
category Collaboration Grids appears to relate to a main generic effect of the deployment of Grid-technology that is the
 increase of (machine and human) collaboration. The three categories appear to address, therefore, characteristics of 
grids on different levels. It is proposed the use of another term in the place of “Collaboration Grids”.  

2. It is proposed to add a section addressing the role of grids in relation to governmental policies (e.g. mention that 
Grid-technology brings the power of information to more citizens etc) and the specific role of the OGF in this picture (
e.g. that the OGF ensures a level playing field for all stakeholders in the field). The addition of such text could help
 perhaps the effort of OGF to approach national governments.
