There is a new build of WebProtege available for download from the
Critical Changes (please read)
- Upgraded to GWT 1.7.
- We made some changes to the directory structure and Eclipse setup to
conform to GWT 1.7. If you are installing WebProtege, please re-read the
Administrator's Guide  for updated instructions. Developers should
look at the Developer's Guide  - the setup for compiling and running
WebProtege has been greatly simplified thanks to the Google Plugin for
- WebProtege now runs in "local mode" by default. Local mode means that
WebProtege will load ontologies from a standalone instance of Protege in
your Servlet container. WebProtege can also be configured to run in
"external server mode" by setting a property value in the
protege.properties file in the <your-servlet-container>/webprotege
directory. External server mode means that WebProtege will load
ontologies from a Protege server running outside of your Servlet
container. The following additional configurations options can be set in
# Defaults to false; change to true to run WebProtege in external server
# Use to specify an alternative location for the metaproject if running
in local mode
# Hostname of the Protege server if WebProtege is running in external
server mode; can also contain a port number
# Username that WebProtege uses to connect to the Protege server if
running in external server mode
# Password that WebProtege uses to connect to the Protege server if
running in external server mode
# Automatic save interval for ontologies if running in local mode (we
recommend the database back-end instead of file mode)
Values of properties listed above should be changed to match your custom
- Project configurations are now saved in the
<your-servlet-container>/webprotege/projectConfigurations folder. The
XML configuration files contain user interface layout information (tabs
to display, number of columns in a tab, portlets to display in a tab,
portlet properties, etc.). The default configuration file is
"configuration.xml". New configuration files are automatically generated
if a user saves the layout for a particular project. Configurations are
stored per user, per project.
- Users can now open multiple ontologies in WebProtege. Each ontology is
displayed in a separate tab.
- Search is now implemented, including the ability to jump to the
location in the class tree of a selected search result (this
functionality is not yet available for the properties tree). The search
text field is located in the top toolbar.
- Added more support for editing; users with write permission on a
particular project are now able to:
a) Create and delete classes in the Classes tab
b) Create and delete properties in the Properties tab
c) Edit string property values in the Properties portlet
d) Edit the domain and range of properties in the Properties tab
- New portlet is available; the BioPortal Search portlet allows users to
search for terms in the BioPortal repository  and import the terms as
references in WebProtege ontologies.
- New portlet is available; the PropertyFieldPortlet allows form-based
editing of property values. The portlet can be configured to use
different widget types for different properties (analogous to slot
widgets in Protege standalone). Available widgets for editing include:
textfield, textarea, HTML pane, instance grid (similar to the
InstanceTable in Protege standalone), external reference, multifield,
combo-box; not working yet... :) The layout of the form has to be done
manually (for now) in the XML configuration file. An example is
available in the "configuration_example_property_field_portlet.xml"
included in the standard distribution.
- The Properties tab now shows different icons for the different
- The Class Tree in the ClassTreePortlet can now be configured to only
show a subtree in the ontology. The root class can be configured in the
configuration XML file of the project, by setting the topClass portlet
property to the full name of a class. Please see the example
configuration file for exact syntax:
- Web links are now opened in a new browser window.
- Better logging in the Servlet container and Protege server logs if
something goes wrong.
- If running in external server mode, WebProtege will cleanly handle
situations in which the Protege server becomes unavailable.
- RPC calls are now available for creating/deleting classes and setting
- Support for multiple change events. Portlets can register listeners
for class and property creation, deletion, and for property value changed.
