[GSA-RG] [Fwd: Re: [jsdl-wg] GSA scheduling extensions to JSDL]

[Ariel Oleksiak]

Thanks Philipp for forwarding this. As you can see JSDL people are 
interested in our plans. Therefore we should first discussed internally how 
we want to step forward, e.g. how to involve information about another 
schedulers, what should be the scope of SDL and where it might be defined, 
etc.
Best regards,
Ariel
