We will go through the list of bugs in Savannah, and discuss whether they are assigned to the right person, and decide on their priority.

There has been some progress on documentation since the last workshop. In particular, there is now an infrastructure in place for automatically generating component documentation from CVS. We will discuss this, the release page on the wiki and other forms of documentation and try to identify areas for improvement.

Discussion of the operation of ncm-ncd and ncm-cdispd, in particular how dependencies between components are handled.

In this session, we will discuss options for improving the experience of the component writer. This could potentially include improvements to CCM libraries to ease the handling of configuration trees in Perl, discussion of libraries currently in use and suggestions for new ones, ...

17 Best practice when writing components

There has been some discussion of coding style on the mailing list. In this session, we will open up this can of worms! Hints and tips from experienced component writers would be welcome, and we will also examine the existing guidelines and see if they need to be updated.
