Welcome to the D4Science.org Wiki.

D4ScienceAn e-Infrastructure operated by the D4Science.org initiative..org is an organisation offering a Hybrid Data Infrastructure service and a number of Virtual Research Environments (VREs).

The D4ScienceAn e-Infrastructure operated by the D4Science.org initiative..org HDI is operated by relying on gCube, an open-source software system specifically designed to develop and operate HDIs enabling the creation of VREs.

The HDI has been realized as a Service Oriented Infrastructure. A Service Oriented Infrastructures is an infrastructure developed according to the Service Orientation principles, this reflects in facilities for the re-usability and dynamic allocation of the resources forming the infrastructure itself. A Virtual Research EnvironmentA ''system'' with the following distinguishing features: ''(i)'' it is a Web-based working environment; ''(ii)'' it is tailored to serve the needs of a Community of Practice; ''(iii)'' it is expected to provide a community of practice with the whole array of commodities needed to accomplish the community’s goal(s); ''(iv)'' it is open and flexible with respect to the overall service offering and lifetime; and ''(v)'' it promotes fine-grained controlled sharing of both intermediate and final research results by guaranteeing ownership, provenance, and attribution. is the materialization of a very flexible and agile application development model based on the notion of Software as a Service (SaaS) in which components may be bound instantly, just at the time they are needed and then the binding may be discarded. According to it, user communities are enabled to define their own applications by simply selecting the application constituents (the services, the collections, the machines) among the pool of resources made available through the infrastructure. The cost of operating each defined VREVirtual Research Environment. is completely outsourced to the infrastructure that by applying economies of scale to the operation of the applications (sharing and re-use) can offer better, cheaper and more reliable applications than single communities can themselves.

The communities of practice are "virtual", ''i.e.'', they are not formal structures, such as departments or project teams. Instead, these communities exist in the minds of their members, are glued together by the connections they have with each other, as well as by their specific shared problems or areas of interest. The generation of knowledge in communities of practice occurs when people participate in problem solving and share the knowledge necessary to solve the problems.;
