[DAIS-WG] Stepping Down as Co-Chair

[Ny Haingo Andrianarisoa]

Dear Mr Foster,

I thank you for your clarification about the "convergence roadmap" and 
for your very interesting report available on your mentioned blog about 
the WS-RT specification advance.

As we oriented to a .NET-based WSRF implementation, we expected to 
validate the connection with grids based on other frameworks (as GT4) in 
a "second" step. We acknowledge that interoperability is essential -as 
many people mentioned- for a durable efficiency and useability.

We will look at WS-RT specification if (when) this latter plays a bigger 
role. For the moment, I believe that we will go on improving our tools 
for database access on a grid because DAIS combined with WSRF seems to 
our eyes to be a modular solution for an easier evolution (according to 
our perspective).

Best regards,
Ny Haingo.
