Major Programming Components

SW Statement: A triple (subject-Predicate-Object) – thousands of these simple 3-tuples are combined in an App. URI- unique name across the entire Internet. Each SW Statement has an URI. Could include a URL, an abstract URN, or IRI (Intl Resrc ID) SW Languages – Has a set of keywords to instruct the SW tools. An Ontology – Has statements that define concepts, relationships, and constraints. Similar to a DB schema or OO class diagram. Use the many existing Ontologies, for better quality and speed. Instance Data – Statements about specific instances; not a generic concept. This forms the bulk of the SW – an ontology containing the concept ‘person’ may be used by millions of instances of ‘person’ Example: The nces site: http://nces.ed.gov/
