Notation of Science Viewpoint Models

Communities

SV communities are modelled using an object diagram. The following table describes the elements used in that diagram.

Table 1 Notation for community diagrams

Figure	Description
	A Package, in UML notation, is a grouping element. Package is used "to group elements, and to provide a namespace for the grouped elements". A package may contain other packages, thus providing for a hierarchical organization of packages. Classes, objects, use cases, components, nodes, node instances etc. can all be organized as packages, enabling a manageable organization of the elements of UML models.
	Objects are used to represent communities and objectives in the RM. The name refers to the represented entity(community or community objective). The stereotype indicates the namespace where the object is grouped. Sometimes the stereotype can be an image. The image can be used in place of the figure. The ODP stereotype for community is an icon of group of people with keyboards: The ODP stereotype for notation is an icon of group four black and grey arrows converging to a point: Each community is linked to its corresponding objective by a line

In the following example diagram (Figure 1) the package represents an Environmental research infrastructure. The infrastructure contains five objects which are all communities and each community is linked to a community objective.
