- Java supported
The 1.4 release of the OpenMI standard includes full definition of the standard both in C# and Java. This means that OpenMI compliant components can be programmed both in C# (or any other .Net language) and in Java. Please note that OpenMI Java compliant models/components and OpenMI .Net compliant component cannot be linked. Also note that the software development kit and the configuration editor provided by the OATC only works with the OpenMI .Net standard.
- OpenMI SDK
In the previous releases software libraries and source code that supported migration of models was released as the utilities package. The utilities package has been reorganized and is now released as the OpenMI SDK. The OpenMI Sdk is released as source code only (no binaries).
- Distribution
The 1.4 release consist of three separate items; the OpenMI standard, the configuration editor, and the software development kit (SDK), as opposed to previous release where everything was included in a single installation file. The official OpenMI standard is released by the OpenMI Association and made available for download from http://www.openmi.org, whereas the OpenMI configuration editor and the OpenMI SDK are released by the OpenMI Association Technical Committee (OATC), both made available for download from http://sourceforge.net/projects/openmi/.
Some of the main reasons for splitting the release into three parts are:- The OpenMI Association develops, maintains, and releases the OpenMI Standard, whereas development of supporting tools and libraries will be done by others. In this respect the OATC is regarded as any other software provider.
- It is not possible to make backward compliant releases of the OpenMI Standard - whenever you change a standard you have a new standard-. Consequently new standard releases should be done only with long time intervals (e.g. every second year). However, the configuration editor and the Sdk can easily be released more frequently. So, splitting the release, makes such asynchronous releases possible.
- OpenMI source license
The OpenMI standard remains under the LGPL license, whereas the configuration editor and the Sdk is released under the "new BSD license". "The new BSD license", is less restrictive as compared to the LGPL license.
- More strict definition of the standard
The OpenMI standard 1.4 now defined as follows: "There are two variants of OpenMI compliance. Components can be either OpenMI 1.4 .Net compliant or OpenMI 1.4 Java compliant. OpenMI .Net compliant components must follow the compliance definition given in the comments in the file ILinkableComponent.cs OpenMI. Java compliant components must follow the compliance definition given in the comments in the file ILinkableComponent.java"
- Namespaces
The namespace for the OpenMI .Net standard is changed from org.OpenMI.Standard to OpenMI.Standard. For the OpenMI Java standard the name space is org.OpenMI.Standard.
