Detailed information about these aspects is defined within the DRM. As described above, the architect may use<br />

the Data Sharing section of the DRM abstract model as a means to organise and share information about the<br />

information sharing within the agency/COI that he or she supports.<br />

The Data Sharing section of the DRM abstract model is shown in Figure 7-1515. As in all previous sections, it<br />

depicts the concepts that are relevant to the chapter. In this instance the model depicts the Data Sharing<br />

concepts for the DRM and the relationships between them. Concepts are expressed as boxes, while<br />

relationships are expressed as arrows.<br />

Figure 7-15: Data Sharing Section of the DRM Abstract Model<br />

The following are definitions for each of the concepts and relationships within Figure 7-1515 above. The<br />

conventions used are:<br />

� Only ‘outbound’ relationships are listed (i.e. those that originate from the concept).<br />

� The concepts are presented in an order that will ensure the best possible understanding and specific<br />

examples are provided where appropriate.<br />

� Though cardinality is not expressed in the figure, the descriptions below may include cardinality (e.g.<br />

‘one or more’) for purposes of clarity.<br />

� Concept names will be capitalised as in the figure itself (e.g. ‘Exchange Package’), while relationship<br />

names will be expressed in italics and without any hyphens that may appear in the relationship name in<br />

the figure (e.g. ‘refers to’). This is done so that the definitions below can take on as narrative a tone as<br />

possible. The reader should therefore be able to easily visually navigate through the figure as they read<br />

the definitions below.<br />

� Each concept will be referred to in a quantity of one (e.g. ‘An Exchange Package refers to an Entity’) for<br />

purposes of simplicity as the figure does not depict cardinality. However, implementations based on the<br />

DRM will introduce cardinality as needed according to their requirements.<br />

� In some cases, concepts that are part of another standardisation area are included in definitions and<br />

examples below. These concepts will not be described further in this section; the reader should<br />

reference the pertinent section for definitions and examples of those concepts.<br />
