VisIVO work in progress
Interoperabilty:
• Aladin + Topcat in the
AstroGrid framework
• AstroNeural tool for
clustering and data mining
in high dimensionality
spaces
• Access to web services
Multiplatform support:
• Linux porting
Implementation:
• Java external libraries interface
• New graphic tools (sampler,
cutting and projection planes…)
• 3D Vectors support
• Multiple scalars/vectors support

VisIVO and VizieR communication layer
VizieR Catalogues
Web Service
Apache Axis is an
implementation of the
SOAP ("Simple Object
Access
Protocol")
submission to W3C
why Axis C++?

many web services are developed
using Axis
• Apache Software Fundation

VisIVO and Aladin
Aladin is an interactive software sky atlas allowing the user to visualize digitized
images of any part of the sky, to superimpose entries from astronomical catalogs
Objects can be selected using a picker
and passed to Aladin to perform further
Aladin can be controlled via commands
operations
sent to its standard input
Using a pipe it is possible to interact with
it from VisIVO
IVOA Interop. Meeting, October 2005
AstroNeural
Data mining algorithm, in collaboration with the Universities of Napoli
and Salerno, AstroNeural project.
