-<p>Conceptually, a dictionary has a logical structure consisting of key-entity pairs. This structure is often referred to as a <em>map</em>, and is a generic indexing mechanism that can abstract commonly used data structures, including associative lists, relational tables, ordered lists, and more. The specification of such specialized structures in terms of key-value pairs is out of the scope of this document.</p>
+<p>Conceptually, a dictionary has a logical structure consisting of key-value pairs. This structure is often referred to as a <em>map</em>, and is a generic indexing mechanism that can abstract commonly used data structures, including associative lists, relational tables, ordered lists, and more.
+	This document provides a mechanism to assert the provenance for these types of data structures, in the most general way, as a collection of key-value pairs, modified through insertions and deletions. Any more specialized structures can be modeled to some extent in terms of these key-value pairs. 
+	Here, we will discuss the provenance of dictionaries structured in terms of key-value pairs. However, how this key-value pair structure is translated to more specialized data structures, is beyond the scope of this document.</p>
 
 <p>For the purpose of provenance, a dictionary entity is viewed as a snapshot of a dictionary data structure, following a sequence of state-changing insertion and removal operations. These  operations result in new snapshots, each snapshot forming an identifiable dictionary entity. Thus, when the structure of a dictionary changes (through insertions or removals), a new dictionary entity is defined, whereas the older dictionary entity remains the same.</p>
