Glue

18-Nov-2004 Andy Lawrence :VO-TECH workshop, Cambridge 9

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

18-Nov-2004 Andy Lawrence :VO-TECH workshop, Cambridge 12

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.

18-Nov-2004 Andy Lawrence :VO-TECH workshop, Cambridge 13

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 ?
