In the lecture on Datasets, we saw that it is possible to represent data in the form of triples. In this assignment, you are asked to illustrate this by encoding information of about metadata a triple-based representation.
The Escher Assignment. Consider a vocabulary where the symbols consist of (a) the types of entities described in the Metadata assignment, i.e. type, predicate, attribute, boolean, (b) the unary type predicates, (c) the binary attributes, and (d) the booleans yes and no. (Yes, the predicates in our vocabulary are symbols in this vocabulary as well as predicates!) Use the relations described in the Metadata assignment to describe these types and predicates and attributes.
To start you off, we are giving you the factoids describing type. See below. Now you do the other types, the predicates, the attributes, and the booleans.
| type.instance(type) |
| type.predicate(type,type.instance) |
| type.attribute(type,type.predicate) |
| type.attribute(type,type.attribute) |
