End of the Beginning for IVOA is now Roy Williams IVOA Technical Lead implementation base (= cost of schema change) 2.0 1.0 1.1 time May 2006 “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
