How is the NVO different from what the Astrophysical Data System (ADS) tried to be a few years ago?
The goals of ADS were similar, however the technology was not available to make the vision a reality 10 years ago. The key technologies that are available now include: increased bandwidth, maturer understanding of data formats, increased number of data archives on-line, greater format commonality of data, emergence of relevant standards (e.g., XML), examples of distributed services now in common use by the community (e.g., ADS abstract service). There has been a tremendous progress in the past decade, both in the amount, quality, and complexity of astronomical data, and in the applied information technology. These advances enable and require a structure much more powerful than the ADS was conceived to be.
