The NVO development project moved into sixth year thanks to supplemental funding from the NSF. The continuation funding allows us to maintain key technology and infrastructure efforts.

A major effort in this quarter has been the preparation of a book describing the core technologies and science capabilities of the Virtual Observatory. The content for the book is being drawn primarily, though not exclusively, from the NVO Summer School lectures and tutorials. The book is intended to function as a handbook for scientists interested in utilizing the VO in their research and for technically-oriented astronomers and programmers wanting to develop their own VO applications and services. The book will be published by the Astronomical Society of the Pacific as part of their conference proceedings series.

Progress was made on the Simple Spectrum Access Protocol (SSAP) and associated spectral data model, and test interfaces and software were developed that validate the SSAP and spectral DM specifications. NVO staff collaborated with an IVOA-constituted tiger team that is charged with simplifying and finalizing the Astronomy Data Query Language (ADQL) and developing a standard Table Access Protocol (TAP). This work is intended to make it easier for catalog and database providers to publish their holdings, and to decouple standard database queries from the more complicated cross-matching functions that are part of the SkyNode specification.

The VOEvent protocol, whose development was spearheaded by the NVO, was endorsed as an IVOA Recommendation. Work is in progress to broaden the use of VOEvent in the gamma-ray burst research community.

End-user experiences with the NVO web site led us to rethink the primary data discovery portal. An NVO tiger team was formed to define the requirements for a new portal and to develop prototype interfaces. Our goal is to release a new, easy-to-use data discovery tool in conjunction with the May 2007 AAS meeting.

respectively.

A summary of the main decision to separate Language, Access and Specification can be found at the VOQL pages at:

As one of the first actions, a new refurbished ADQL document has been created to serve as a starting point for internal discussions. The document can be seen at:
