Progetto di un sistema per la conservazione a lungo termine e a norma di legge di documenti elettronici

NOT AVAILABLENell\u27articolo viene presentato il lavoro svolto dall\u27Istituto di Fisiologia Clinica del CNR per la progetta- zione di un sistema di gestione elettronica dei dati prodotti durante l\u27attivit? clinica. Per garantire una conservazione di lungo periodo e il rispetto dei termini di validit? legale, ? stato necessario utilizzare strumenti e metodi di prevenzione nei confronti dell\u27invecchiamento dei supporti, dell\u27obsolescenza dei formati software e della scadenza delle firme digitali. Il sistema ? stato progettato rispettando la normativa CNIPA e in con- formit? con lo standard ISO OAIS. Il risultato finale ? stato la realizzazione di un sistema molto semplice dal punto di vista architetturale, modulare e flessibile in vista di un\u27esportazione verso altri enti. Particolare attenzione ? stata posta agli strumenti di indicizzazione e all\u27utilizzo di software open source

Proxy agents for adaptive delivery of multimedia

Adaptive delivery of multimedia means the capability of adapting content exploitation according to available resources, session parameters and user profile, in order to improve quality of service. It can be exploited to support people with disabilities in accessing available services, or to change the way of exploiting a resource according to working conditions. For example a text document can be delivered as audiostream when an user is driving, or when it cannot exploit a content as it is, because he is blind. Different kinds of multimedia fruition allow also to conceive new value added services and new models of interaction with contents. Here we present architecture design, and prototypal implementation, of a framework that can be integrated, transparently, in web applications, to add mobile agents based adaptive delivery. Mobile agents technology has been exploited to augment flexibility of classical solutions and to develop advanced facilities. We set up a case study on semantic and location based information retrieval to demonstrate effectiveness of our approach
