General Terms

Community of Practice
A term coined to capture an "activity system" that includes individuals who are united in action and in the meaning that "action" has for them and for the larger collective. 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.
Community of Practice.
An e-Infrastructure operated by the D4Science.org initiative.
An operational combination of digital technologies (hardware and software), resources (data and services), communications (protocols, access rights and networks), and the people and organizational structures needed to support research efforts and collaboration in the large.
iMarine Gateway
The access point to iMarine products and services. The most common products are delivered through collaborative Virtual Research Environments that render services running in the D4Science e-Infrastructure, but can access interoperable infrastructures including Cloud and Archives.
iMarine Project
A project funded through the European Commission's 7th Framework Programme to support policy making based on scientific data and analysis taking direct benefit from a large and distributed e-Infrastructure for data collection, harmonization and analysis.
iMarine e-Infrastructure
The iMarine e-Infrastructure enables global collaborative data analysis on a wide variety of formats and sources, and effectively integrates information across domains. The advantages of the e-Infrastructure are manifold; centralized deployment and management of resources eliminate the costs of operation a myriad of hardware and software resources, the distributed network of resources offers elastic access and usage of computing resources, and the large pool of expertise enables effective development projects using the latest technologies.
Virtual Research Environment
A 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.
Virtual Organization
A dynamic set of individuals or institutions defined around a set of resource-sharing rules and conditions. All these virtual organizations share some commonality among them, including common concerns and requirements, but may vary in size, scope, duration, sociology, and structure.
VOVirtual Organization;
Virtual Organization;
Virtual Research Environment.

Technologies-related Terms

It is a web-based cooperation environment supporting teammates activities including files sharing.
gCube Hosting Node.
LCG File Catalog.
National Grid Initiative.
Site BDII.
Storage Element.
Virtual Organization Membership Service.
Web Coverage Service
Web Coverage Service
Supports the networked interchange of geospatial data as "coverages" containing values or properties of geographic locations. Unlike the Web Map Service, which returns static maps (server-rendered as pictures), the Web Coverage Service provides access to intact (unrendered) geospatial information.
Web Feature Service
OpenGIS Specification that supports INSERT, UPDATE, DELETE, QUERY and DISCOVERY of geographic features. WFS delivers GML representations of simple geospatial features in response to queries from HTTP clients. Clients access geographic feature data through WFS by submitting a request for just those features that are needed for an application.
Web Mapping Service
OpenGIS Specification that standardizes the way in which Web clients request maps. Clients request maps from a WMS instance in terms of named layers and provide parameters such as the size of the returned map as well as the spatial reference system to be used in drawing the map.
Web Service
Self-contained, self-describing, modular application that can be published, located, and invoked across the Web. Web services perform functions that can be anything from simple requests to complicated business processes. Once a Web service is deployed, other applications (and other Web services) can discover and invoke the deployed service.
Web Feature Service
See Workload Management System or Web Mapping Service.
Worker Node.
Workload Management System
It comprises a set of Grid middleware components responsible for the distribution and management of tasks across Grid resources, in such a way that applications are conveniently, efficiently and effectively executed
