“end of the beginning”
IVOA urgent challenge
• What do we have for data-center manager?
•
•
•
•
•
•
“How can my data become part of VO?”
“Where can I read about VO?”
“What software can help me to be VO-compliant?”
“How do I expose my images, catalogs and spectra?”
“How many people do I need to be VO-compliant?”
“Is everything going to change again next year?”
• New Interest Group “Implementations” ?
• Each project reports back on “their” data centers and
VO-compliance
Essential VO in 2006
• Standard services:
– catalog: Skynode
– image: SIAP 1.0
– spectrum: SSAP
• Discovery
– data & services: Registry
– literature: ADS, astro.ph
Let’s get these to
REC this summer!
1. Skynode and ADQL
exposes a relational database
• Function
– What are the tables
– What are the attributes of a table
– Please run this query
• How can we simplify ADQL?
– select a,b,c from table
• Work on scaling &db implement
• not complexity of ADQL
2. Image Access
• SIAP 1.0, simple model, let’s
keep it!
• multiple 2D images
• Standardize time?
• The “new SIAP” needs a new
name
• Datacube, On-demand, time-series,
single dataset, etc etc
t

3. Spectral Access
• SSAP *must* be ready this summer
– 2 years late
– no more time for subtleties
– complexity in the data product, NOT in the XML
4. Registry
• User experience
•
•
•
•
•
Search forms more important than SOAP
Publisher’s account and login
Publishing/updating many records
Librarians and validators
Schema must be “explainable”
• Schema change is a HUGE disruption
• Must be a VERY good reason
How you can help
• Robust Implementations
• Need list of relevant software for each protocol
• SIAP, SSAP, Skynode, STC
• For the Data Center
• Which registry for them (Registry of Registries?)
• Report back to Implementation IG
• Logging of VO services
• If you run a registry
• Alert your curation team when new record arrives
• Run auto-verifier regularly
And ......
• More astronomy
• Spectral lines, VOEvent, Ontology, Literature,
Footprints, Theory (Nbody), Filters
• Get it right
• Complex publishing, STC, Provenance,
Authentication, Preservation, Characterization
• Scaling Up
• Async, Security, VOSpace, Plastic
• Crossmatch, Cutouts, Coadds, Mining
