Minutes: There are currently two open bug repportsreports; one about unit conversion that does not handle missing values correctly and one about comparison of time horizons. Adrian and Jan will fix those bugs.

...

Minutes: There is a fine activity on the help forum. We try to answer help request quickly (within a day), but unfortunately this sometimes takes longer. Hence, everyone is encouraged to subscribe the the help forum in order to receive a mail notification when new help issues are submitted. Jan will keep an eye on the forum and forward the help forward new help issued to someone in the OATC issues to OATC members if such issues are not already answered within a reasonable time.

3.2.3 IQuality and IQuantity

...

We will focus on the spatial issues at the next OATC meeting in Delft. However, since Andrea is attending this meeting, it could be wise to start the thinking process now, utilizing his knowledge about GIS and specifically OpenMI GIS.

Minutes:
TODO:
Make notes on issues above and , the time issue (using .Net DateTime with offset), events (define our own event type or used platform specific types, passing object (using generics). All this to be elaborated further before and at the next OATC meeting. (make references to the child pages posted by Gena and others). Based on the discussions in the meeting Jan has updated the standard in the trunk on source forge. See UML below:

3.3 Development and release road map

...

Since we are dealing with a standard release we must follow the procedure for OpenMI standard releases. So far we do not have such procedure formally accepted by the OAEC. On this agenda (point 4.1) is a proposal for a procedure. So, let's discuss this first and then see how we can fit some dates into this.

Minutes:
with With respect to version 1.4.1 release, we will go into beta by the next OATC meeting in Delft, and a release on December 20 th 2008. Everyone in encouraged to start using the GUI version 1.4.1 now.

Rob: Maybe it is (sometimes) a solution to serialise the object as XML or JSON and then exchange them from Java to C# and back. There might be open source solutions, e.g. http://woxserializer.sourceforge.net/^{Image Removed}. Of course performance is a potential issue.

4. OATC Procedures

4.1 Proposal for procedures for OpenMI Standard releases

From Jan: I have at task from one of the previous OpenMI Association Executive Committee meeting to elaborate a proposal for OpenMI Standard release procedure. These procedures will define the rules for how to go from OpenMI Standard release version x to OpenMI standard version x+1. I think that the OpenMI standard it selves is the most important asset of the OpenMI Association, which also means that rules for how this standard may be change becomes very important. I thought a lot about it (apparently, more difficult that I first anticipated), and I *Minutes:* have now written my first idea down in draft form. I would appreciate if we, at the OATC meetings, could discuss these ideas.
Please review the Proposed procedure for OpenMI Standard releases.

Minutes:
It was agreed that a Wiki would be the best solution. On a longer term we may want to use a real content management system, which makes nice formatting possible, but for now the contents of the pages are considered more important that the appearance. Adrian will investigate if WSL can provide a server to host the WIKI and Stef will investigete investigate if Deltares can host. We aggree agree that our current wiki for OATC (Confluence) is the best choice. Jan will make sure that this issue is on the agenda for the next AOEC meeting.

Confluence can be also customized to make layout look more professional like using plugin like Adaptivist Theme Builder . If we have time - we can also use current web site design materials for it.

...

(from Rob Knapen( There are some people expressing interest to contribute to the OpenMI
Java development, any ideas how this can be set up? Is it something the
OpenMI TC would like to handle, as part of the OpenMI open source
community?

Minutes:
Curret status: the The Java SDK is under MyOpen Source on source forge , is difficult for people to find.
Rob and Andrea will make a wiki HowTo page describing the Java SDK and explaining how to use it and where to download it.

...

From Jan: For some reason I like to have a full copy of OpenMI SourceForge repository on my local disk. However, currently this is about 4GB data (takes forever to download). One of the problems is the HEC model data that for some reason is checked into the repository. Could we somehow remove these data files and possibly also review if some of the branches are outdated and can be removed.

Minutes:
Gena will create new my openMI open source version control repository force and and .......
Minutes:on source forge and move the HEC files to this repository
