 ## Introduction
 
-A semantic annotation is the attachment of semantic metadata to a resource - in this case, a dataset. 
-What makes the annotation "semantic" is that the resource is linked to a well-defined term in an Ontology.  In this way, semantic annotation provides access to precise definitions of concepts, and clarifies the relationships among concepts in a machine-readable way, using the Web. The process of creating semantic annotations may seem tedious, but the payoff is enhanced discovery and reuse of your data. 
+A semantic annotation indicates a relationship between some semantic metadata and a resource - in this case, a dataset, or some other element of a dataset (e.g. an attribute). What makes the annotation "semantic" is that the resource is linked to a well-defined term in an Ontology.

 The main differences between semantic annotation and simply adding keywords are: 
 - semantic annotations can be read and interpreted by computers
