The design for 1.0.0 is lacking the ability to query individual collections and directories of documents. This would be a very useful feature and is available to the underlying Java Client API.

The following tests fails at "assertThat(st.getContext(), is(equalTo((Resource)dirgraph1)));" , the context returned by st.getContext() is null always.

@test
public void testGetStatementsInMultipleContexts()
throws Exception
{
testAdminCon.begin();
testAdminCon.add(micah, lname, micahlname, dirgraph1);
testAdminCon.add(micah, fname, micahfname, dirgraph1);
testAdminCon.add(micah, homeTel, micahhomeTel, dirgraph1);
testAdminCon.commit();

CloseableIteration<? extends Statement, RepositoryException> iter = testAdminCon.getStatements(null, null, null, false, dirgraph1);
try {
int count = 0;
while (iter.hasNext()) {
count++;
Statement st = iter.next();
logger.debug("Test 1" +st.getContext());
logger.debug("Test 1" +st.getObject().stringValue());
assertThat(st.getContext(), is(equalTo((Resource)dirgraph1)));
}
assertEquals("there should be three statements", 3, count);
}
finally {
iter.close();
iter = null;
}

When inserting triples using the method "add(Resource subject, URI predicate, Value object, Resource... contexts)", the object "Alice", gets inserted into the database as a URI and not as String "Alice". The query below returns empty dataset. As a result of this , email data gets inserted but when running size() method, RDFParseException is thrown as it complains the an email (for example '[email protected]) is not a valid URI format.

SELECT ?o
FROM http://marklogic.com/test/context5
WHERE
{
?s ?p ?o.
FILTER (?o = "Alice")
}

Sample code:

Resource context5 = testAdminCon.getValueFactory().createURI("http://marklogic.com/test/context5");
URI alice = testAdminCon.getValueFactory().createURI("http://example.org/people/alice");
URI name = testAdminCon.getValueFactory().createURI("http://example.org/ontology/name");
URI person = testAdminCon.getValueFactory().createURI("http://example.org/ontology/Person");
Literal alicesName = testAdminCon.getValueFactory().createLiteral("Alice");
testAdminCon.add(alice, RDF.TYPE, person,context5);
testAdminCon.add(alice, name, alicesName,context5);

testAdminCon.hasStatement(john, homeTel, johnhomeTel, false) generates the following ASK query which is incorrect syntactically. This occurs only when the context is not specified or if one of the context is explicitly specified as null.

Scenarios:

1. testAdminCon.hasStatement(john, homeTel, johnhomeTel, false)
2. testAdminCon.hasStatement(john, homeTel, johnhomeTel, false, null)
3. testAdminCon.hasStatement(john, homeTel, johnhomeTel, false, null, dirgraph)
4. testAdminCon.hasStatement(st1, false);
5. testWriterCon.hasStatement(st1, false, null);

The method con.prepareTupleQuery(String query, String baseuri), con.prepareBooleanQuery(Stirng query, String baseuri) etc are missing

On evaluating the query obtained by prepareGraphQuery and prepareUpdateQuery method when used with a baseuri doesn't give the correct result and always returns empty result set.

Sesame's org.openrdf.model.impl.URI (and undelrying org.openrdf.model.impl.URIImpl) strictly check URI's. In MarkLogic, URI are constrained as xs:string so its possible to generate URI (ex. graph names)that Sesame classes (derived or otherwise) will choke on.

Investigate what chicanery might be required to bypass this limitation and table discussion to broader group.

Statement st1 = vf.createStatement(john, fname, johnfname);
con.add(st1,dirgraph);

con.size(context) returns the number of triples in the entire database and not of the specified graph

Able to create a null MarkLogic client object with the default construtor MarkLogicRepository().

We should throw an error and/or provide more handling.

The following code fails when 'context' is not set as it looks like it is not handled in 'performAdd' method in 'MarkLogicClientImpl' class

//testAdminCon is an instance of RepositoryConnection
InputStream in = MarkLogicRepositoryConnectionTest.class.getResourceAsStream(TEST_DIR_PREFIX
+ "directory.ttl");
testAdminCon.add(in, "", RDFFormat.TURTLE);

2. testReaderRepository = new MarkLogicRepository("localhost", restPort, "reader", "reader", "DIGEST");
   testReaderRepository.initialize();
   testReaderCon = (MarkLogicRepositoryConnection) testReaderRepository.getConnection();
3. testReaderCon.prepareUpdate("CREATE GRAPH ").execute(); creates a graph which is not expected as the user doesn't have rest-writer role.

The method con.prepareQuery() throws UnsupportedOperationException for non SPARQL language instead of UnsupportedQueryLanguageException. Other prepare methods throw the correct exception

I am creating a case for this question so that we don't lose track of it.
Sesame doesn't allow creation of URI unless the character ':' is present in the uri string (org.openrdf.model.impl.URIImpl) . Marklogic does allow creation of contexts without ":". So, can this pose a problem in that all the graphs created through any other methods in MarkLogic should essentially have ':' so that they can be used within Sesame ?

At this point, it looks like we don't have a way of setting default ruleset(s) for the database from within marklogic-sesame in the MarkLogicRepositoryConnection class. Something like

public void setRulesets(SPARQLRuleset ruleset...)
public SPARQLRuleset [] getRulesets()

I assume that in the method "public RepositoryResult getStatements(Resource subj, URI pred, Value obj, boolean includeInferred, Resource... contexts)", when includeInferred is set to true, it applies the default rule set on the triples and returns the statements. But there doesn't seem to be a way to set default ruleset(s) as of now.

need to build out export

con.size(null) should provide the number of triples without context. But it throws the following exception.

con.size() is expected to return the number of triples in the entire db (triples with or without contexts). But the result returned is incorrect. Upon checking 'MarkLogicTupleQuery.java', the value of pagelength has been hardcoded to 50 and all select queries now return only a maximum of 50 results.

The following triple is inserted into db. The Xquery version runs and provides “true” which is expected whereas the method in Sesame returns false. I just want to be sure if the Xquery and java method are meant to have the same functionality. If so, then this might be an issue.

sem:triple
sem:subject
http://marklogic.com/baseball/players#119
/sem:subject
sem:predicate
http://marklogic.com/baseball/players#team
/sem:predicate
sem:object
http://marklogic.com/baseball/rules#Tigers
/sem:object
/sem:triple

XQuery:

xquery version "1.0-ml";
import module namespace sem = "http://marklogic.com/semantics" at "MarkLogic/semantics.xqy";
let $query := '
PREFIX bb: http://marklogic.com/baseball/players#
ASK FROM http://marklogic.com/Graph1
WHERE
{
<players#119> <players#team> <rules#Tigers>.
}
'
let $boolean := sem:sparql($query, (), "base=http://marklogic.com/baseball/")
return $boolean

Sesame:

String query1 = "PREFIX bb: http://marklogic.com/baseball/players#"+
" ASK FROM http://marklogic.com/Graph1"+
" WHERE"+
" {"+
" <players#119> <players#team> <rules#Tigers>."+
" }";

boolean result1 = testAdminCon.prepareBooleanQuery(QueryLanguage.SPARQL, query1,"http://marklogic.com/baseball/").evaluate();

This bug tracks all the scenarios where the exceptions thrown in marklogic-sesame are not the ones specified in the spec but rather the one thrown by the ML client.

1. As per spec, 'IllegalArgumentException' should be thrown by con.prepare*Query()
   for example for con.prepareGraphQuery() if a graph query is not provided (DESCRIBE or CONSTRUCT), IllegalArgumentException should be thrown. Right now, a different exception is thrown whenever a wrong query is passed
2. If the SPARQL query has syntax errors, 'MalformedQueryException' should be thrown but right now, we throw the exception returned by the ML client.
3. Running update statement with user with only rest-reader role should throw "UpdateExecutionException".
   "testReaderCon.prepareUpdate("CREATE GRAPH ").execute();"
4. Adding malformed .ttl file should throw RDFParseException

1. In MarkLogicRepositoryConnection.java, each of the below prepareQuery methods call prepareTupleQuery instead of the method " public MarkLogicQuery prepareQuery(QueryLanguage queryLanguage, String queryString, String baseURI)".

2. Also the returned instance of type 'Query' or 'MarkLogicQuery' is not executable (as in no execute() method unlike instances of TupleQuery etc)

   // prepareQuery entrypoint
   @OverRide
   public Query prepareQuery(String queryString) throws RepositoryException, MalformedQueryException {
   return prepareTupleQuery(QueryLanguage.SPARQL, queryString, null);
   }
   @OverRide
   public Query prepareQuery(String queryString, String baseURI) throws RepositoryException, MalformedQueryException {
   return prepareTupleQuery(QueryLanguage.SPARQL, queryString, baseURI);
   }
   @OverRide
   public Query prepareQuery(QueryLanguage queryLanguage, String queryString) throws RepositoryException, MalformedQueryException {
   return prepareTupleQuery(queryLanguage, queryString, null);
   }

Sesame supports adding zip and gzip files using add(InputStream in, String baseURI, RDFFormat dataFormat, Resource... contexts) method. Are we planning on supporting them as well ?

Better write performance is achieved using an internal write cache, which batches up and periodically flushes statements to ML. For symmetry we already provide a BackgroundResults cache for reading from SPARQL results.

As per Sesame, when ‘null’ is explicitly specified as context in getStatement(), it returns the statements that don’t have a context associated with it . I believe that this is the case for con.size() as well. The following snippet is from a test case for Sesame project.

// get statements with either no context or context2
CloseableIteration<? extends Statement, RepositoryException> iter = testCon.getStatements(null, null, null, false, null, context2);

The following tests fails in the final assert (Assert.assertEquals(0L,testAdminCon.size())) which is expected to succeed as the con.remove(Iteration itr) is expected to remove the entire contents of the db

@Test
public void testRemoveStatementIteration()
    throws Exception
{
    testAdminCon.begin();
    testAdminCon.add(fei, fname, feifname, dirgraph);
    testAdminCon.add(fei, lname, feilname, dirgraph);
    testAdminCon.add(fei, email, feiemail, dirgraph);
    testAdminCon.commit();

    Assert.assertEquals(3L,testAdminCon.size());

    Iteration<? extends Statement, RepositoryException> iter = testAdminCon.getStatements(null, null,
            null, false);

    testAdminCon.remove(iter);
    Assert.assertEquals(0L,testAdminCon.size());
}

1. For the method query.evaluate (int, int), if either start or pageLength or both are negative, the entire result set is returned. Is that an expected behavior or should an error be thrown ?
2. Also if pageLength is out of bounds (as in size of result set is 10, start is 8 and pageLength is 5), results 8, 9 and 10 are returned with no errors thrown. IS that an expected behavior as well ?

When subject, predicate or object is null in con.add(Statement st, Context ct) and con.add(Resource r, URI u, Value v) , a null pointer exception is thrown. Just wanted to check if we may want to handle it better may be wrap the exception along with a more clearer message

The triples inserted from query console are not returned using 'SELECT' query from within Sesame.

Steps:

1. Run INSERT DATA { GRAPH http://abcd { "fbefbj".} } in Queryconsole.
2. URI ur = vf.createURI("http://abcd");
   logger.debug("Size of abcd is"+ testAdminCon.size(ur));

returns the size as zero. The query executed from Sesame is "SELECT * WHERE { GRAPH http://abcd {?s ?p ?o .} }" returns an empty result set but which as expected returns the result set when run from Query console.

Statement st = vf.createStatement(john, lname, johnlname, dirgraph);
testAdminCon.add(st);
Assert.assertTrue(testAdminCon.hasStatement(st, false, dirgraph));

The code above generates a query which misses the graph name and also is of incorrect syntax.
