Protege 3.4 Beta update (build 516)

There is a new beta build available on our Web site:

Changes in Core Protege
----------------------------------------
- Made several performance optimizations for the client-server mode, =

namely that RMI can compress data before sending it over the wire. More =

information about configuration settings for the Prot=E9g=E9 server are =

available on the wiki [1].
 =

- Added debug and performance monitoring support in the Prot=E9g=E9 logger =

for client-server mode. More information is available on the wiki [2].


Changes & Bug Fixes in Protege-OWL
----------------------------------------
- Optimized performance of the OWL Individuals tab (not the Instances =

Tab!) in client-server mode for classes with large number of individuals =

that have browser slots configured. The MultiResourceWidget now uses a =

different structure for retrieving property values from the server that =

contains among other things, the individual and the browser text. This =

means that computation of the browser text can now be done on the =

server, thus preventing multiple calls across the network. Performance =

of the OWL Individuals tab is also much improved by using the =

compression mentioned above. Finally, we optimized several parts of the =

UI code to minimize the number of network calls.

- Added a fix for possible name conflict problems at parse time (e.g., =

if you import an OWL file into a OWL database) by using a random number =

generator for the anonymous class and individual names.
 =

- Added a fix for the native writer that saves each import with its own =

namespace.
 =

- Creating a subproperty will now create a property that has all the =

types of the super-property.

- Fixed several refresh problems in the UI that occurred after renaming =

an entity (this applies to both Frames and OWL), changing the range of a =

datatype property, etc.

- Fixed a problem in the OWL Properties tab that made properties appear =

twice when designating a property as functional.

- Fixed some memory leaks when disposing a project.

- The Add type button in the OWL Individuals tab is now disabled if no =

individual is selected.

- Fixed some bugs that could involve data loss, including a) values of =

sub data properties can be lost when an OWL ontology is parsed, and b) =

database import of projects with individuals can become corrupted.


As always, a web-based version of the release notes is available on our =

site [3].
