Read below sentence and tell me its type. You only need to return one type from type_list:['Author List', 'Reference', 'Content','Meaningless','Acknowledge']. Here is the sentence """A primary tenet of the RVM model is that RDF is the lowest level of representation and in being the lowest level of representation, RDF is used to model all aspects of computing. Thus, RDF is used to define those data structures that are common in computing such as the lists, the sets, the arrays, the maps, the vectors, the stacks, the program counters, the heaps, the trees, the objects, the instructions—in general, the general-purpose modeling construct: the graph. Thus, RDF is used not just for representing metadata, RDF is used for representing data. When all information is placed in the URI address space, computing is at a new level of abstraction. This level of abstraction is a shared memory space that is built on the existing Web infrastructure. """ Your entire response should be in English, and in all capital letters.
