A Question

Is there a correlation between sunspotcomplexity and maximum magnetic

flux? Type of question we would like to ask

Can one answer it using VOs?

How would you use VOs to do it?

Status

Beta client available but Mostly workflow & services

Little semantic support

Custom communicationprotocol

Incomplete documentation

Too fat

Draft Ontologies forsemantic support

Draft Collaborative Spaces


18/19


Plans for 2005

Client WSDL support

Semantic composition aids Thin client using remote execution agent

Semantic & Knowledgebase Data, services, models & results KB

Collaborative Spaces Cleaner web interface

Queries using knowledge bases


19/19


Conclusions

Beta client available for adventurous

Crude collaborative spaces open for

business
