Glueworkflow : clunky startdistributed storage : crude startsingle sign on : simple plans, no deployment global issue
resource discovery : good start registry : ok dictionary : ok semantics : next key step
global wave : sem.web, ontologyfind a pragmatic next step
18-Nov-2004 Andy Lawrence :VO-TECH workshop, Cambridge 10
Data Federation
data interoperability : good startdata integration : crude start : circle xmatch multi-match; probabilistic prior information not just tables !
science -- algorithms -- codeneed semantics "what can I do with this data?"
18-Nov-2004 Andy Lawrence :VO-TECH workshop, Cambridge 11
multi- views of a Supernova Remnant
Shocks seen in the X-ray
Heavy elementsseen in the optical
Dust seen in the IR
Relativistic electrons seen in the radio

Services
data access : good startdata query : good startdata manipulation : bare start this is the goldmine tools : viewing, plotting, measuring : need lots exploration : multi-D visualisation, clustering analysis : FTs, model fitting, correlation analysis
much exists : needs VO integration.

personal hot list
single sign on astro soln / industry soln / academic soln
data integration what does it mean ?
semantic web / ontology AI pipe dream or real next step ?
data services whats ready to rock and roll ?
