Hi, You can check whether the dataset contains a specific named model with dataset.containesNamedModel() [1]

We have the following method in com.hp.hpl.jena.db.IDBConnection in jena 2: ------------------------------------------------------------------------------------------------------------ containsModel boolean containsModel(String name) throws RDFRDBException Test if a given model is contained in the database. Parameters: name - the name of a model which may be in the database Returns: Boolean true if the model is contained in the database Throws: RDFDBException RDFRDBException Since: Jena 2.0 ------------------------------------------------------------------------------------------------------------ This method is used to check whether a given model exists in the underlying database. So is there a corresponding method to check for models in database in jena 3 in org.apache.jena.sdb.sql.SDBConnection.java class or in any other jena 3 jar? Regards, Ashwani
