## Overview
|
|
||||||
|
|
||||||
Ontology is the philosophical study of being. Generally *things* are split into two broad categories: **abstract** and **concrete** things. These words are "terms of art" and their definition is not standardized in any way.

### Instantiation
|

An entity is said to **instantiate** a property if said entity bears a connection to the property. For example, a human instantiates the property of *being human* and a man instantiates the properties of *being human* and *being a man*.

## Overview
|
||||||
|
|
||||||
|
The **Resource Description Framework** (RDF) is the foundational representation language of the Semantic Web. The basic building block of RDF is the **triple** containing a **subject**, **predicate**, and **object**. Global identifiers of resources are represented as [[uri|URIs]] (or, more generally, IRIs). These URIs can be expressed more compactly as [[uri#CURIEs|CURIEs]].

## Overview
|
||||||
|
|
||||||
|
A **uniform resource identifier** (URI) is a unique sequence of characters for identifying some physical or abstract resource. URIs are further generalized to **internationalized resource identifier**s (IRIs) which allow using characters from any language, provided there exists a standard web encoding of the characters.

### URLs
|
||||||
|
|

A **uniform resource locator** (URL) is a URI that specifies the means of finding the represented resource. The most commonly used schemes are `http` and `https`.

## CURIEs
|
||||||
|
|
||||||
|
A **compact URI** (CURIE) is a denser representation of URIs. In its simplest form, it consists of a namespace and identifier separated by a colon. For example, `geo:England`.
