Method Detail

loadModel

@Deprecated
public static Model loadModel(String urlStr)

Deprecated. Use FileManager.get().loadModel(urlStr)

Load a model

Parameters:

urlStr - The URL or file name of the model

loadModel

@Deprecated
public static Model loadModel(String urlStr,
                         String lang)

Deprecated. Use FileManager.get().loadModel(urlStr, lang)

Load a model or attached a persistent store (but not a database).

Parameters:

urlStr - The URL or file name of the model

lang - The language of the data - if null, the system guesses

loadModel

public static Model loadModel(String urlStr,
              String lang,
              String dbUser,
              String dbPassword,
              String modelName,
              String dbType,
              String driver)

Load a model or attached a persistent store. Tries to guess syntax type. Database paramters only needed if its a database.

Parameters:

urlStr - The URL or file name of the model

lang - The language of the data - if null, the system guesses

dbUser - Database user name (for RDB/JDBC)

dbPassword - Database password (for RDB/JDBC)

modelName - The name of the model

dbType - Database type (e.g. MySQL)

driver - JDBC driver to load.

Returns:

Model

loadModel

guessLang

@Deprecated
public static String guessLang(String urlStr,
                          String defaultLang)

Deprecated. Use FileUtils.guessLang

Guess the language/type of model data. Updated by Chris, hived off the model-suffix part to FileUtils as part of unifying it with similar code in FileGraph.

• If the URI of the model starts jdbc: it is assumed to be an RDB model
• If the URI ends ".rdf", it is assumed to be RDF/XML
• If the URI end .nt, it is assumed to be N-Triples
• If the URI end .bdb, it is assumed to be BerkeleyDB model [suppressed at present]

Parameters:

urlStr - URL to base the guess on

defaultLang - Default guess

Returns:

String Guessed syntax - or the default supplied

guessLang

@Deprecated
public static String guessLang(String urlStr)

Deprecated. Use FileUtils.guessLang

Guess the language/type of model data

• If the URI of the model starts jdbc: it is assumed to be an RDB model
• If the URI ends ".rdf", it is assumed to be RDF/XML
• If the URI end .nt, it is assumed to be N-Triples
• If the URI end .bdb, it is assumed to be BerkeleyDB model

Parameters:

urlStr - URL to base the guess on

Returns:

String Guessed syntax - null for no guess.
