... We describe a Data Inventory Service (DIS) that uses Virtual Observatory protocols to discover, organize and present astronomers with a rapid precis of what is known about a given region of the sky. ... Since the DIS caches results from services, users can quickly browse catalog and image results. ... The DIS is built on top of early protocols developed as part of the US National Virtual Observatory effort, the Cone search and Simple Image Access protocols, and uses the VOTabe format extensively. ...

... Because the catalogues currently described by UCDs cover many different domains, UCDs can be used to describe a large fraction of astronomical concepts. The different Virtual Observatory (VO) pro jects, collaborating in the IVOA (International Virtual Observatory Alliance) have therefore decided to support UCDs, and to collaborate to define a new set of standard metadata. ... It uses a new syntax, and a list of atomic keywords from which UCDs are built. ...

After matching image point sources to ob jects in each of the catalogs and fitting world coordinate systems to them using the IMWCS program, we find mean residuals between observed and catalog star positions of between 0. 09 and 0. 25 for the latest catalogs. ... Unix shell scripts written for each catalog set up an initial FITS header for each of the 1728 images with the center being the mean position of the ob jects found in that image. ...

In this poster we describe the terabytescale SuperCOSMOS Science Archive2 (SSA), which is a recasting of the SSS ob ject catalogue system from flat files into an RDBMS, with an enhanced user interface. We describe some aspects of the hardware and schema design of the SSA, which aims to produce a high performance, VOcompatible database, suitable for data mining by `power users', while maintaining the ease of use praised in the old SSS system. ...
