All participation will be governed by university terms of service usage policies. Distributed mass storage arrays will be integrated using the iRODS middleware that will allow people to set policies for veracity and access. The architecture for the LL will be layered and take advantage of emerging cyberinfrastructure and cloud computing services. Additionally, the private storage available through a university service could support trusted ranges of records from family finance to health. For example, alums could take advantage of streams of lectures or campus events, webinars or blog discussions, or peer-based social media networks. Such a service will not only help students lead successful digital lives beyond the university, but can also serve as a link to alums who stay in touch and participate in campus activities. The school's assurance that such resources will persist will serve as a trusted covenant between the institution and its constituents. The vision of the lifetime library is to provide trusted storage and associated services for students and alums for their entire lives. We aim to provide trustworthy and easy to use services that help our students and alumni sustain, extend, and use the information resources that compose their knowledgebase over a lifetime. Universities help young people develop development and management skills for these assets and prepare lifetime learners and problem solvers who maintain connections to their schools. At home and at work, people create, replicate, and extend their digital knowledgebases over time. When students graduate, they may preserve some traces of their digital lives, but typically, these traces disappear when their computers are retired or commercial services expire. Over the course of several years on campus, students use a variety of devices (e.g., laptops, desktops, PDAs, mobile phones) for creating, managing, and using these data. In addition to course-related digital objects, students acquire enormous streams of social interactions (e.g., Facebook, Twitter, SMS, LinkedIn streams) and data files (e.g., music, photos, videos). Today, most of the course materials, personal notes, and assignments done at universities originate in digital form (e.g., web-pages, word processed files, spreadsheets, simulations, codebases, databases) some of which are in proprietary systems or formats (e.g., Blackboard). In the past, the physical resources were discarded, sold or lost, or stashed in attics. Over the course of their university experience, students acquire physical resources (e.g., books, notes, files) as well as mental resources (e.g., explicit and tacit knowledge, social relationships). Students come to university to develop personal knowlegebases that will help them achieve their goals in life. Project Profile The LL Concept: Building and sustaining digital knowledgebases
