12.1.7. RDF collection

Rdf:parseType= “Collection” attribute ¶

As we saw in the previous section, we cannot close a container. The container specifies that the resources it contains are members-it does not specify that other members are not allowed.

The RDF collection is used to describe groups that contain only the specified members.

The collection is described by the property rdf:parseType= “Collection”.

In recent years, Geographic Information Systems (GIS) have undergone rapid development in both theoretical and practical dimensions. GIS has been widely applied for modeling and decision-making support across various fields such as urban management, regional planning, and environmental remediation, establishing geographic information as a vital component of the information era. The introduction of the “Digital Earth” concept has further accelerated the advancement of GIS, which serves as its technical foundation. Concurrently, scholars have been dedicated to theoretical research in areas like spatial cognition, spatial data uncertainty, and the formalization of spatial relationships. This reflects the dual nature of GIS as both an applied technology and an academic discipline, with the two aspects forming a mutually reinforcing cycle of progress.
