Data Spaces are containers of Entities (or Entity Sets) defined by Class Properties that include: Attributes (Characteristics) and Associations (Relationships). In the Semantic Data Web realm, URIs also identify individual Entities or Entity Sets typically referred to as non-information resources (preferably: Generic or Data Resources). This is the position we take in our soon to be released paper about deploying Linked Data.
