Because read and write operations on the web of data are usually required for data elements rather than RDF assertions (to create the assertion "Mary goes to school X", you will probably will want to create "Mary", the "school X", and the "goes to" relationship), it's easier if we name what "things" we want to write about.
So, since "Mary" is assumer to be person named "Mary", we probably way to say just that "mary" a "person". Of course, something that people can do is go to school. So we can say "People" "goto" "school". But now things start to get confusing... how do I create the notion of "Person" in RDF? Or the assertion that people go to school? To make all those concepts easier to grasp, we can call each of those "entities". So Person is an entity and "Mary" is another entity. All the entities available for read/write operations and the relationships between them can be specified using a Core Model.
Using a core model this makes read/write operations much easier.
S3QL makes of the core model of S3DB for managing entities and their relationships.
