There are numerous commercial digital asset management systems, but most of them are relatively expensive and meant for in-house management. In the meanwhile alternative solutions have been developed for searchable interactive repositories of media for professional use, education and research. Web-based digital libraries and indexes of literature have been available on the internet for a few years now. In many cases a focus on specified areas is given and published information is disseminated in this way. However, researchers, educators and practitioners in architecture and civil engineering also depend on various sources of information that are stored and delivered in a multitude of media formats. Some of that information is case-based and built incrementally from previous experiences.
