Ciao: Developing an Architecture for User Profile Management



K Broun


The Office of Information Services is responsible for NIST's research library and publications program. In the course of developing new electronic and print versions of one of those publications, the Technicalendar, we realized we had an opportunity to develop an infrastructure to broadly manage information about the users of OIS products and services, and to deliver more customized products to those users. The 'Ciao' (Current Information and Awareness Online) architecture encompasses a central database that maintains general information about our users and provides a modular structure to easily add or change services for which we want to offer profiling and customization to our users. For example, employees receiving the Technicalendar can choose print or electronic format, which sections to receive, whether to filter by keywords, how frequently updates should be delivered, and whether full text or brief formats are sent. Ciao incorporates user data from NIST-wide directory and security databases, and allows us to keep the user information in our library management system current. We use the library system's API to authenticate Ciao users before they can set up or modify their profiles, enabling us to maintain a single user ID/PIN for each user across many of our services.
