Building Infrastructures Using Service Oriented Architectures



In 1995, the US National Agricultural Library (NAL) and four American land-grant universities launched a project to build a distributed web gateway to distribute quality and evaluated agriculture-related information and resources. This modest AgNIC Alliance has grown to include 46 member institutions and an extensive network of inter-connected web-based resources.

In 2003, the Alliance articulated a vision for it to become one of the “premier comprehensive web portals for international agriculture and the related sciences using state-of-art technologies.” It wanted to serve as a “model for collaborative and synergistic provision of discipline specific electronic information.”

To assist the Alliance and one of its members, the Arid Lands Information Center, Precipice articulated a technical vision and developed a technical architecture based on the service oriented architecture (SOA) paradigm. The architectural prototype demonstrated how to to deliver targeted and user-focused services across academic, agency and public domains.
