Catalogue Intersection: Beyond Basic Cross Correlations
Matching objects listed in different catalogues by position is a primary need for VO users: we want to find counterparts (or absence of counterparts)... -
Space-Time Metadata for the Virtual Observatory
We discuss the hierarchy of objects that are to contain the metadata pertaining to space and time for the Virtual Observatory. The design needs to be... -
Enabling Outreach with Virtual Observatories
Virtual observatories are potentially excellent vehicles for public outreach and education because they can put anyone in direct contact with the... -
The Canadian Virtual Observatory Project
The Canadian Virtual Observatory (CVO) project is now funded at a level that places it among the major Virtual Observatory (VO) projects in the... -

The CCD Sky Patrols and Plate Archives
We report on the recent efforts to extract the data from the CCD and photographic sky patrol archives as well as to evaluate them and use for... -
Early Virtual Science: Some Lessons for the AVO
Experience with ASTROVIRTEL, scientific analysis of current large data sets, and detailed preparation for the truly huge future missions especially... -
System to Study Evolution of Radio Galaxies as a Part of a Virtual Radio Observatory
The system for study of radio galaxies evolution using photometry data has been created at the site http: //sed.sao.ru. It consists of several... -
IDHA Image Archive Model
The Image archive model described here has been developed within the scope of the IDHA (Images Distribuées Hétérogènes pour l’Astronomie) project.... -
VOTable: Tabular Data for the Virtual Observatory
The VOTable format is now an agreed upon XML standard for representing tabular data in the VO context. Tabular data are an important part of the data... -
Authentication and Authorization Architecture for AstroGrid and the Virtual Observatory
Although the bulk of the data useful to the Virtual Observatory are in the public domain and have uniform, read-only access from archives, there are... -
Towards an AVO Interoperability Prototype
A working interoperability prototype is an important goal for year 1 of the AVO interoperability Work Area. This prototype aims to federate a set of... -
The AstroGrid Pilot Programme
We describe the AstroGrid Pilot Programme, a set of testbeds conducted during AstroGrid’s one-year Phase A study, and intended to complement the... -
Artificial Intelligence Tools for Data Mining in Large Astronomical Databases
The federation of heterogeneous large astronomical databases foreseen in the framework of the AVO and NVO projects will pose unprecedented data... -
