An RDF Model.

An RDF model is a set of Statements. Methods are provided for creating resources, properties and literals and the Statements which link them, for adding statements to and removing them from a model, for querying a model and set operations for combining models.

Models may create Resources [URI nodes and bnodes]. Creating a Resource does not make the Resource visible to the model; Resources are only "in" Models if Statements about them are added to the Model. Similarly the only way to "remove" a Resource from a Model is to remove all the Statements that mention it.

When a Resource or Literal is created by a Model, the Model is free to re-use an existing Resource or Literal object with the correct values, or it may create a fresh one. [All Jena RDFNodes and Statements are immutable, so this is generally safe.]

This interface defines a set of primitive methods. A set of convenience methods which extends this interface, e.g. performing automatic type conversions and support for enhanced resources, is defined in ModelCon.

System Properties

Firewalls and Proxies

-DsocksProxyHost=[your-proxy-domain-name-or-ip-address]

To use an http proxy, include on the command line:

-DproxySet=true -DproxyHost=[your-proxy] -DproxyPort=[your-proxy-port-number]

Alternatively, these properties can be set programatically, e.g.

   System.getProperties().put("proxySet","true");
   System.getProperties().put("proxyHost","proxy.hostname");
   System.getProperties().put("proxyPort",port_number);

Method Detail

size

public long size()

size will return the number of statements in a concrete model, for a virtualized model such as one created by an inference engine, it will return an estimated lower bound for the numberof statements in the model but it is possible for a subsequent listStatements on such a model to discover more statements than size() indicated.

isEmpty

public boolean isEmpty()

Answer true iff the model contains no explicit statements (ie it's size is zero, listStatements() would deliver the empty iterator).

listSubjects

public ResIterator listSubjects()

List all resources which are subjects of statements.

Subsequent operations on those resource may modify this model.

listNameSpaces

public NsIterator listNameSpaces()

List the namespaces used by predicates and types in the model. This method is really intended for use by the RDF/XML writer, which needs to know these namespaces to generate correct and vaguely pretty XML.

The namespaces returned are those of (a) every URI used as a property in the model and (b) those of every URI that appears as the object of an rdf:type statement.

getResource

public Resource getResource(java.lang.String uri)

Return a Resource instance with the given URI in this model. This method behaves identically to createResource(String) and exists as legacy: createResource is now capable of, and allowed to, reuse existing objects.

Subsequent operations on the returned object may modify this model.

getProperty

public Property getProperty(java.lang.String nameSpace,
                            java.lang.String localName)

Return a Property instance with the given URI in this model. This method behaves identically to createProperty(String,String) and exists as legacy: createProperty is now capable of, and allowed to, reuse existing objects.

Subsequent operations on the returned property may modify this model.

createResource

public Resource createResource()

Create a new anonymous resource whose model is this model. This bnode will have a new AnonId distinct from any allocated by any other call of this method.

Subsequent operations on the returned resource may modify this model.

createResource

public Resource createResource(AnonId id)

Create a blank node resource with a specified identifier. The resulting bnode will be equal to any other bnode with the same AnonId (even if they are in separate models - be warned). The intended use for this method is to allow bnode round-tripping between Jena models and other representations.

This method may return an existing bnode with the correct AnonId and model, or it may construct a fresh one, as it sees fit.

Operations on the result may modify this model

createResource

public Resource createResource(java.lang.String uri)

Create a new resource associated with this model. If the uri string is null, this creates a bnode, as per createResource(). Otherwise it creates a URI node. A URI resource is .equals() to any other URI Resource with the same URI (even in a different model - be warned).

This method may return an existing Resource with the correct URI and model, or it may construct a fresh one, as it sees fit.

Operations on the result Resource may change this model.

createProperty

public Property createProperty(java.lang.String nameSpace,
                               java.lang.String localName)

Create a property with a given URI composed from a namespace part and a localname part by concatenating the strings.

This method may return an existing property with the correct URI and model, or it may construct a fresh one, as it sees fit.

Subsequent operations on the returned property may modify this model.

createLiteral

public Literal createLiteral(java.lang.String v,
                             java.lang.String language)

Create an untyped literal from a String value with a specified language.

createLiteral

public Literal createLiteral(java.lang.String v,
                             java.lang.String language,
                             boolean wellFormed)

Deprecated. since Jena2. It is no longer legal to have a language tag on a well-formed XMLLiteral. Use the 2-argument form of createLiteral 55 instead. Create a literal from a String value with a specified language. An existing literal of the right value may be returned, or a fresh one created.

createLiteral

public Literal createLiteral(java.lang.String v,
                             boolean wellFormed)

Create a literal from a String value. An existing literal of the right value may be returned, or a fresh one created. The use of the wellFormed flag is to create typed literals of type rdf:XMLLiteral, without error checking. This should only be use when the lexical form is known to already be in exclusive canonical XML.

createTypedLiteral

public Literal createTypedLiteral(java.lang.String lex,
                                  com.hp.hpl.jena.datatypes.RDFDatatype dtype)

Build a typed literal from its lexical form. The lexical form will be parsed now and the value stored. If the form is not legal this will throw an exception.

Note that in preview releases of Jena2 it was also possible to specify a language type. Changes to the RDF specification mean that this is no longer legal except for plain literals. To create a plain literal with a language tag use createLiteral 55 .

createTypedLiteral

public Literal createTypedLiteral(java.lang.Object value,
                                  com.hp.hpl.jena.datatypes.RDFDatatype dtype)

Build a typed literal from its value form.

Note that in preview releases of Jena2 it was also possible to specify a language type. Changes to the RDF specification mean that this is no longer legal except for plain literals. To create a plain literal with a language tag use createLiteral 55 .

createTypedLiteral

public Literal createTypedLiteral(java.lang.Object value)

Build a typed literal label from its value form using whatever datatype is currently registered as the the default representation for this java class. No language tag is supplied.

Specified by:

createTypedLiteral in interface ModelCon

createStatement

public Statement createStatement(Resource s,
                                 Property p,
                                 RDFNode o)

Create a Statement instance. (Creating a statement does not add it to the set of statements in the model; see Model::add). This method may return an existing Statement with the correct components and model, or it may construct a fresh one, as it sees fit.

Subsequent operations on the statement or any of its parts may modify this model.

createList

public RDFList createList()

listObjects

public NodeIterator listObjects()

List all objects in a model.

listObjectsOfProperty

public NodeIterator listObjectsOfProperty(Property p)

List all objects of a given property. .remove() is not implemented on this iterator.

listObjectsOfProperty

public NodeIterator listObjectsOfProperty(Resource s,
                                          Property p)

List the values of a property of a resource.

contains

public boolean contains(Resource s,
                        Property p)

Determine whether this model contains any statements with a given subject and property.

containsResource

public boolean containsResource(RDFNode r)

determine if the RDFNode r appears in any statement of this model. (containsRDFNode is a horrible name, and in any case, even literals will be resources one day)

contains

public boolean contains(Resource s,
                        Property p,
                        RDFNode o)

Determine if an (S, P, O) pattern is present in this model, with null allowed to represent a wildcard match.

contains

public boolean contains(Statement s)

Determine if a statement is present in this model.

containsAny

public boolean containsAny(StmtIterator iter)

Determine if any of the statements returned by an iterator are contained in this model.

containsAll

public boolean containsAll(StmtIterator iter)

Determine if all of the statements returned by an iterator are contained in this model.

containsAny

public boolean containsAny(Model model)

Determine if any of the statements in a model are also contained in this model.

containsAll

public boolean containsAll(Model model)

Determine if all of the statements in a model are also contained in this model.

isReified

public boolean isReified(Statement s)

Determine if this Statement has been reified in this Model.

getAnyReifiedStatement

public Resource getAnyReifiedStatement(Statement s)

Find or create a ReifiedStatement corresponding to a Statement.

removeAllReifications

public void removeAllReifications(Statement s)

Remove all reifications (ie implicit reification quads) of _s_.

removeReification

public void removeReification(ReifiedStatement rs)

Remove a particular reificiation.

listStatements

public StmtIterator listStatements()

List all statements.

Subsequent operations on those statements may modify this model.

listStatements

public StmtIterator listStatements(Selector s)

List the statements matching a selector.

A statment is considered to match if the test method of s returns true when called on s.

listStatements

public StmtIterator listStatements(Resource s,
                                   Property p,
                                   RDFNode o)

Find all the statements matching a pattern.

Return an iterator over all the statements in a model that match a pattern. The statements selected are those whose subject matches the subject argument, whose predicate matches the predicate argument and whose object matches the object argument. If an argument is null it matches anything.

createReifiedStatement

public ReifiedStatement createReifiedStatement(Statement s)

Answer a ReifiedStatement that encodes _s_ and belongs to this Model.
result.getModel() == this
result.getStatement() .equals ( s )

createReifiedStatement

public ReifiedStatement createReifiedStatement(java.lang.String uri,
