If you've obtained the source code of BridgeDb, you should be able to compile with a simple:

mvn clean install

(If you want to ignore failing tests, e.g. because you are not online, add this option: -Dmaven.test.failure.ignore=true)

Library dependencies

If you do not use all mappers, you do not need to include all libraries in the dist directory in your project.

Here is a brief overview that will help you to find out which ones you need. For questions, you can always contact our mailing list.

  • org.bridgedb.jar - always needed. This includes the tab-delimited file driver.
  • - includes the BioDataSource enum, often needed
  • org.bridgedb.webservice.cronos.jar - needed for CRONOS webservice
  • org.bridgedb.webservice.synergizer.jar - needed for Synergizer webservice
  • org.bridgedb.webservice.picr.jar - needed for PICR webservice
  • org.bridgedb.server.jar - the BridgeRest SERVER, not needed if you only want to access BridgeRest or BridgeWebservice as client
  • - Contains the batchmapper command line tool

org.bridgedb.jar and do not need any other jar files to work. Most of the other jar files in dist/ are part of the SOAP libraries needed only for some of the webservices. Look in the lib directory and build.xml of the respective mappers to find clues which libraries are needed by which service.

Additional packages added for version 2 (mainly for URI support needed for OpenPHACTS) org.bridgedb.utils - adds logging and some utils - Needed for all of modules below org.bridgedb.sql - Alternative SQL database optimized for speed not size* Another version of the Webservice. Runs with and IDMapper

org.bridgedb.rdf Loads DataSources from rdf and miriam (with URI suppport)

org.bridgedb.uri.sql Adds support for URIs (requires org.bridgedb.sql) org.bridgedb.uri.loader Loads RDF linksets into org.bridgedb.uri.sql. Also creates transtive linksets* Extends* with URI supports from org.bridgedb.uri.sql

Configuration For the URI/OpenPHACTS packages ONLY!

Where are configuration files loaded from?

BridgeDB looks for the configuration files from the following locations with priority given to those at the top of the list (ie location 1 is a higher priority than 2 etc). Once it finds a configuration file the other locations are ignored.

  1. Directly in the run directory (Mainly for java *.jar runs)
  2. Environment Variable BRIDGEDB_CONFIG : can be used to point to any location
  3. Tomcat configuration folder : $CATALINA_HOME/conf/BridgeDb
  4. conf/BridgeDb : Allows tomcat 7 to pick up $CATALINA_HOME/conf/BridgeDb even if it can not get $CATALINA_HOME
  5. ../conf/BridgeDb : Allows tomcat 6 to pick up $CATALINA_HOME/../conf/BridgeDb even if it can not get $CATALINA_HOME
  6. Using classLoader getResource : This will pick up the files included in Jars and Wars.

Configuration files

(There is no local properties files included)

This is the recommended place to overwrite individual property values of any other *.properties file. will overwrite values with the same key in any other properties file. Properties not overwritten in local will keep their original values.

To install local properties you need to.

  1. Create a file
  2. Store it in a location as described above
  3. Copy the keys from the original file

(Default file is included in build and can be found in org.bridgedb.utils/resources)

This file contains the local setup information which MUST be configured correctly for the service to run. It is essential that the database user, password and database name are correct.

You MUST either supply local values matching your local setup or setup your data stores to use the defaults. The recommened way to overwrite properties is to add a property with the exact (case sensitive) key to

Database Dependency

(for the org.bridgedb.sql package and its dependencies ONLY) MySQL version 5 or above MUST be installed and running
MySQL databases and users MUST be created with CREATE, DROP, INDEX, INSERT, ALTER, UPDATE, DELETE, and SELECT permissions.

Consult the file for the defaults, or copy and amend the configuration file to reflect your own setup.

If you are using the default mysql accounts and databases then execute the file mysqlConfig.sql from the BridgeDB root directory which will configure your local mysql with the BridgeDB defaults

mysql -u root -p < mysqlConfig.sql

Note that the sql script will fail, without reverting changes made up to the point of failure, if any of the user accounts or databases already exist.

RDF Repository and Transitive Directory Dependency

(For org.bridgedb.rdf package and its exstensions ONLY)

BridgeDB uses OpenRDF Sesame RDF engine and this is included automatically via maven.
WARNING: All directories MUST exists and the (linux) user running tomcat MUST have READ/WRITE permission set! Some of the OpenRDF error message are unclear if this is not the case.

See and change the appropriate property to point to the correct directory. A Sesame SailNativeStore(s) will be created automatically as long as the loader can create/find the directory,

We recommend changing the relative directories to absolute directories. Please ensure the parent directories exist and have the correct permissions.

The settings for testing (and therefore compilation) can be left as is as long as the testing user would have permission to create and delete files there.

The BaseURI variable is no longer used but may be in the future so is worth setting correctly.

Other Configuration files

(Default file is included in build and can be found in org.bridgedb.utils/resources)

Edit this to change the logger setup. The default can be found in the Utils Resource directory Please refer to the log4j documentation for more information.


(Included in the build and found at org.bridgedb.rdf/resources)

RDF format of all the BridgeDB DataSource(s) and Registered UriPatterns, Found in $BRIDGEDB_HOME/org.bridgedb.rdf/resources

This file defines all the URI patterns that will match every BridgeDB DataSource. Warning: As additional UriPatterns are constantly being found and created this file is subject to continuous updates. Having a local DataSource.ttl is therefore highly discouraged as it will block future updates being discovered. Instead please push any changes into the version inside the source code. This file is NOT effected by and you cannot change existing or add additional datasource URI patterns through If you require local additions that should not become general usage (such as commercial uriPatterns) then the suggested approach is for you to change the code to use multiple dataSource files.

(Included in the build and found at org.bridgedb.uri.sql\resources)

This file defines the lenses to be used in the system. See Scientific Lenses over Linked Data for more information on what lenses are.

Can and should be added to using

WARNING: As the Lens work is still evolving it is subject to alterations and the format of this file could be changed at any time. Having a local is highly discouraged as it will block future updates being discovered. Instead please push any changes into the version inside the source code.

Local additions that should not become general usage (such as commercial lens) can be added to the file.

Note: the fourth part of the key
only serves to keep the keys unique and can have any value. If extending a key we suggest using local** as the fourth part of the justification key to ensure not overwriting general additions.

(Included in the build and found at org.bridgedb.uri.sql\resources)

This file maps RDF Graphs/Context with the UriPatterns found in that graph. This allows Map functions to supply a graph name rather than a list of targetUriPatterns

Data in the included file is OpenPHACTS specific.

Data Loading

All tests should load their required data at the start of the tests. To load the test data into the live sql use the method SetupWithTestData in the URI loader package. The IMS project also has a data loader which should be used if the IMS is the deployed project.


For URI/OpenPHACTS packages

If you've obtained the source code of BridgeDb, you should be able to compile with a simple:

mvn clean install

Note that for the maven build to run all tests: 1. The MySQL database MUST be running and configured as above. 2. (Optional) http://localhost:8080/OPS-IMS to be running the war created by the URI webserver Server module, with test data which can be loaded using the class SetupWithTestData in the URI Loader module. Maven will skip the client tests if the localhost server is not found.

OPS Webservice Setup.

Make sure your file matches:

  • The SQL databases included user names and password
  • The rdf parent directories are setup (and accessible) as above.

or you have set up the default databases etc from

Deploy $BridgeDb/*.war to something like your local tomcata webapps directory To setup databases and add test data run org.bridgedb.uri.loader.SetupLoaderWithTestData. The easiest way is within eclipse since you can set the OPS_IMS_CONFIG environment variable within the run configuration, Netbeans unfortunately does not allow environment variables to be set within the IDE. (Optional) Deploy $BridgeDb/ Both wars share the same SQL data.

Note: If Installing the OpenPhacts IMS and or the OpenPhacts QueryExpander the*.war should not be deployed but instead the war appropriate to the other project should be deployed. See the readme within the other projects for more details.
