 We would like to that the folks at JHU/APL for their implementation of [STIX2NEO4J.py](https://github.com/opencybersecurityalliance/oca-iob/tree/main/STIX2NEO4J%20Converter), which this code is based on.  
 
 Only the DataSink (for storing STIX data) part of the DataStore object has been implemented.  The DataSource part is implemented as a stub.  However, the graph database can be queried using the neo4j cypher langauge within

-The main concept behind any graphs are nodes and edges.  STIX data is similar as it contains relationship objects (SROs) and node objects (SDOs, SCOs and SMOs).  The division of data in STIX is a natural fit
-into the Neo4j model.  Additional edges are provided by STIX embedded relationships, which are expressed as properties in node objects. 
+The main concept behind any graphs is nodes and edges.  STIX data is similar as it contains relationship objects (SROs) and node objects (SDOs, SCOs and SMOs). Additional edges are provided by STIX embedded relationships, which are expressed as properties in STIX node objects. This organization of data in STIX is a natural fit for graph models, such as neo4j.  
 
 The order in which STIX objects are added to the graph database is arbitrary. Therefore, when an SRO or embedded relationship is added via the DataStore, the nodes that it connects may not be present in the database, so the relationship is not added to the database, but remembered by the DataStore code as an unconnected relationship. Whenever a new node is 
 added to the database, the unconnected relationships must be reviewed to determine if both nodes of a relationship can now be represented using an edge in the graph database.
