2. Files that were modified
Files that were modified include:
build.xml - added Jena support:
Jena is a Java framework for building Semantic Web applications. Jena provides a collection of tools and Java libraries to help develop semantic web and linked-data apps, tools and servers.
Python.g - different types of sparql statements
Tuple.java - Modified constructor
PyTuple.java - added Name of Data Source
CodeCompiler.java - Sparql query node

3. Sparql queries -how to // Initialize variables here.
$sparql_stmt::prefixes = new ArrayList<com.MJJ.common.Pair<String, String>>();
$sparql_stmt::selectVars = new ArrayList<String>(); $sparql_stmt::fromClauses = new ArrayList<String>(); $sparql_stmt::orderBys = new ArrayList<com.MJJ.common.Pair<String, String>>();
$sparql_stmt::whereClauses = new ArrayList<com.MJJ.common.WhereClause>();
$sparql_stmt::limits = new ArrayList<String>();
$sparql_stmt::exprs = new ArrayList<expr>();
$sparql_stmt::queryType="";
$sparql_stmt::temp="";
$sparql_stmt::values = new ArrayList<String>();
$sparql_stmt::exprs = new ArrayList<com.MJJ.common.Pair<expr, String>>();

4. Demo - Part 1 # First we need to create an ARQ model
SPARQL(CREATE family_demo)
# Set the prefix we want to use
SPARQL(PREFIX fam : <
# Insert a little family into the database
SPARQL(INSERT { fam:Dad fam:fatherOf fam:SomeGuy; })
SPARQL(INSERT { fam:Mom fam:motherOf fam:SomeGuy; })
SPARQL(INSERT { fam:Dad fam:fatherOf fam:SomeGirl; })
SPARQL(INSERT { fam:Mom fam:motherOf fam:SomeGirl; })

5. Demo - Part 2 SPARQL(INSERT { fam:Dad fam:fatherOf fam:AnotherGirl; })
SPARQL(INSERT { fam:Mom fam:motherOf fam:AnotherGirl; })
SPARQL(INSERT { fam:SomeGuy fam:sonOf fam:Dad. })
SPARQL(INSERT { fam:SomeGuy fam:sonOf fam:Mom. })
SPARQL(INSERT { fam:SomeGirl fam:daughterOf fam:Mom. })
SPARQL(INSERT { fam:SomeGirl fam:daughterOf fam:Dad. })
SPARQL(INSERT { fam:AnotherGirl fam:daughterOf fam:Mom. })
SPARQL(INSERT { fam:AnotherGirl fam:daughterOf fam:Dad. })

6. Demo - Part 3 # Get all the daughters of Mom from the database
SPARQL(SELECT * WHERE { ?daughters fam:daughterOf fam:Mom. })
# Get all the sons of Dad from the database
SPARQL(SELECT * WHERE { ?sons fam:sonOf fam:Dad. })
# Get all the parents of SomeGuy
SPARQL(SELECT * WHERE { fam:SomeGuy fam:sonOf ?parents. })
# We're done, so let's drop the model.
SPARQL(DROP GRAPH family_demo)

7. RDF Triple Store using INSERT
With a bunch of INSERT statements we create a table
SPARQL(INSERT { fam:Dad fam:fatherOf fam:AnotherGirl; })

8. SPARQL SELECT
This SPARQL Select statement uses the WHERE clause to find all the "daughters" in the table

9. SPARQL MULTIPLE SELECTS
This select statement shows all the "Parents" from the Table. It knows that Mom and Dad are both Parents.

10. SPARQL DELETE
Delete a specific row from the table using WHERE clause.

11. SPARQL DROP TABLE
Drops the entire table.

12. Pair.java
added needed functionality to make select statement be more granular by the time we want to use it to query the db. modified the language to allow for SELECT * FROM ... case
public class Pair<E, S> {
protected E left;
protected S right;
public Pair(E left, S right){
this.left = left;
this.right = right; }
public E getLeft(){
return left; }
public S getRight(){
return right;

13. WhereClause: subject, predicate, object
Public class WhereClause {
protected String subject;
protected String predicate;
protected String object;
public WhereClause(String subject, String predicate, String object){
this.subject = subject;
this.predicate = predicate;
this.object = object; }
public String getSubject(){
return subject;}
public String getPredicate(){
return predicate;}
public String getObject(){
return object; }
public String toString(){
StringBuffer sb = new StringBuffer();
sb.append(subject == null ? "null" : subject);
sb.append(predicate == null ? "null" : predicate);
sb.append(object == null ? "null" : object);
return sb.toString(); }}
