Actually, this is something that I have already given some thought to. Since there haven't been any package submissions to LAVA until now, I hadn't rushed to make a standard. I think the filename should have 'lava' in it. For example lava_lib_rcf_insert_typeconversion-1.0.9-1. What do you think?
In addition to the package name, the other issue is installation location. VI Packages that are distributed as being part of LAVA, should be installed under a LAVA sub-palette. At least, that is the goal. Your package is an RCF plugin so this isn't an issue right now. However If you want to setup a template for doing that then that would be a great help to others.
I like all the other fields:
The only one I have an issue with is the homepage URL. This should point to the main download page of your file on LAVA, not the discussion thread.
