Thanks Ingo. This sounds like a great plan. I will take care of the items listed below in the initial draft.
The idea of also writing a Java executor sounds like a good one. I guess there is no substituition of understanding what is lacking than to do it for real. I suggest we spend todays meeting time discussing how we can achieve this and the mechanics.
On the editor: Ignore my comments, I keep forgetting we already have it done.
Of the initial draft, I will add in the 'applicableTo" element (note the naming convention!). I guess one of the questions / concerns I have is how this would work in practice. This assumes that a tool has already been able to accuratley determine the "applicableTo" criteria ie identify its an Intel architecture would be hard even if it is IIS.
I got a little side-tracked with some personal things this week so haven't yet completed the thesaurus and riskRanking work. It will be done before the weekend is out.

Folks,
I will try to participate today - let's see if it works overseas. ;o)
Sorry for my silence during the last weeks, but we are currently
setting up a very gainful project right now, that will last till December.
Some annotations regarding the "draft"
- - naming: please remove all non-alpha chars from the names.
names containing blanks or other special characters are always problematic
during data processing (normalization etc. pp.)
"VulnDB's" or "Risk Ranking" are not acceptable
- - naming: please hold on to a strict naming convention, lets say
all lowercase or java convention (starting with a lowercase char),
e.g. "Risk Ranking" -> "riskRanking"
- - Remedy group: I don't think that a "Patch" is sufficient here. Most often
the remedy does not consist of a simple patch, but of an abstract
instruction. Thus the remedy should contain a textual description too.
- - ApplicableTo left out: I guess this is *the* criterion one would like to
search for. The default scenario for me is: "I have got app server x and
web server y on platform z, so what issues are known for that?"
Everything else is only a refinement (e.g. "only those of the last month",
"only the GPLd ones", etc.)
So the applicableTo thing is a central point for retrieval.
BTW the ApplicableTo as found in the current VulnXML DTD is one of
the most over-worked things there: the cardinality and structure of the
parts should be exactly what we need, so we could just adopt that part.
- - data entry stuff: I still dont understand why we should write yet another
"skunkwork" editor to perform data entry based upon xml:schema while
having a completely functional DTD based editor online that could be
easily adapted.
As for the extension of the VulnXML execution logic:
I think it would be better to write a working executor based upon
what we have now as a proof-of-concept (the python based stuff
is rather outdated and I dont know, if someone is willing to adapt it)
before thinking of extensions.
Let's discuss the the minutiae later on. :o)
Kind regards
Ingo
