In late 2007, the National Radio Astronomy Observatory (NRAO) launched Data Vault, a feature-rich web application
for simplified access to NRAO data archives. This application allows users to submit a Google-like free-text search, and
browse, download, and view further information on matching telescope data. Data Vault uses the model-view-controller
design pattern with web.py, a minimalist open-source web framework built with the Python Programming Language.
applications. This application supports plug-ins for linking data to additional web tools and services, including Google
Sky. NRAO sought the inspiration of Google's remarkably elegant user interface and notable performance to create a
modern search tool for the NRAO science data archive, taking advantage of the rapid development frameworks of
web.py and GWT to create a web application on a short timeline, while providing modular, easily maintainable code.
Data Vault provides users with a NRAO-focused data archive while linking to and providing more information wherever
possible. Free-text search capabilities are possible (and even simple) with an innovative query parser. NRAO develops
all software under an open-source license; Data Vault is available to developers and users alike.
