Hi Paul,

I read the InformationWeek article and find that there are a lot of
commonalities between DCML and OGSA. I also find many
differences;

- Grid is for networked sites (data centers), single site is rather special
case.
- DCML is language-centric vs. OGSA is service-centric.
- DCML framework and OGSA grid may provide the same functions
  (services). But OGSA specified how to construct its components
  based on Service Oriented Architecture for flexibility and
interoperability.

Thanks,
