[foaf-protocols] generating certificates and trying out foaf+ssl

[Story Henry]

I have placed a little program to generate and produce the foaf that  
needs to be added to one's foaf file in sommer.dev.java.net . It is in  
the misc/FoafServer directory

Run it like this:

$ ant jar   #make sure your JAVA_HOME is set to java 6

$ java -cp dist/FoafServer.jar  
net.java.dev.sommer.foafserver.utils.GenerateKey -uri http://bblfish.net/people/henry/card#me 
  -pass hell0
publish this triples that go with this N3 (use cwm to merge it into an  
rdf file)
# the ontology is very speculative here.
# we only need a way of linking a person to his x509 certificate, of  
which all that is required is the signature

@prefix wot: <http://xmlns.com/wot/0.1/> .
<http://bblfish.net/people/henry/card#me>
     is wot:identity of [
           a wot:x509Certificate;
           wot:sigType wot:md5WithRSAEncryption;
           wot:sigValue  
"4d85aae9e4c4afc0384fc10b56a9cd61125e804717c0bbe324a7c85d2c9da14696a0c9eb7714e3d375a2ff0edf363c484c5dfcd779985de8ed9f29c6926f827778553bc2984276fea9c69d051ef6c7579fc610fee67feebd112c800664dc86bbc9f1794ae0d0b79f6f502fcda5c4bd24026312f1faabbc2aaae2ec35c2f5244c"
           ] .

the public and private keys are in the stored in cert.pkcs
you can list the contents by running the command
$ openssl pkcs12 -clcerts -nokeys -in cert.pkcs | openssl x509 -noout - 
text

The foaf there can be added to your foaf file, and then you can query  
Juliette's protected foaf

$ java -cp dist/FoafServer.jar -Djavax.net.ssl.keyStore=cert.pkcs - 
Djavax.net.ssl.keyStorePassword=hell0 - 
Djavax.net.ssl.keyStoreType=PKCS12  
net.java.dev.sommer.foafserver.utils.TestGet https://www.pipian.com/rdf/tami/juliette-protected-location

You will get N3 back, only if your foaf file returns the correct  
signature.

Ok. So clearly the rdf in the foaf file is not yet properly defined.  
Should one put the signature value, or something else? This should be  
defined. Perhaps worth playing with first to get an idea of what is  
happening. Then we could work out which ontology to use, or which  
relations need to be created.
