Semantic Grid
The term semantic grid refers to a grid computing approach according to which information, resources and services are described in machine-readable form. This is to make it easier to find resources in the grid and add them automatically, which helps in establishing virtual organizations . The semantic descriptions represent meta information and are usually made with the technologies of the Semantic Web , such as. B. RDF realized.
Based on the Semantic Web , the Semantic Grid can be defined as: "an extension of the existing grid in which information and services are given well-defined meanings in order to enable computers and people to better cooperate." (Source: Semantic Grid Group)
This view of the semantic grid was first formulated in the context of e-Science , because it was determined that such an approach seemed necessary in order to create a high level of easy-to-use and seamlessly interlocking automation that enables flexible collaboration on a global level and to be able to make calculations in a distributed manner.
The use of Semantic Web - and other technologies in the field of knowledge management in grid applications - is sometimes referred to as a knowledge grid . The Semantic Grid extends this by applying these technologies within the grid middleware .
Some activities related to the Semantic Grid are coordinated by the Semantic Grid Research Group of the Global Grid Forum (GGF).
