The description of concepts prioritized both breadth and detailedness of relations between concepts. In this sense, we decided to continue with the creation of our own ontology with our own elements and predicates while reusing reasoning inherent in RDF, Dublin Core, ISAAR, FOAF, and CDWA, EAD, and CRM. The combinatorial use of these allowed our concept or subject elements to be described in high detail. For example, we included predicates specifically to account for the multiple potential names of a concept, by reusing the RDFs and ISAAR name predicates. While ISAAR is generally used for authority records, we deemed its “Other forms of name” category as a helpful predicate to include. This inclusion allows for a greater linkage of ideas (for example, Technological Revolution is accounted for as another name for the Second Industrial Revolution). We have also included a predicate to describe or include a summary based on the idea behind the Dublin Core’s description predicate. Furthermore, our model allows for a detailed description of places, dates, persons, and events related to the subject or concept in question. As with Persons, the utilization of subclasses is ideal for including greater levels of detail if they are available for each of these relations.
