Hi,=20

   Reto implemented an version of foaf+ssl in the OSGi based, RDF =
powered, apache Clerezza Content Management system.=20

    http://incubator.apache.org/clerezza/

To get it to work, do the following

1. check it out
   $ svn co =
http://svn.apache.org/repos/asf/incubator/clerezza/trunk/org.apache.clerez=
za.parent

2. compile it with mvn (>=3D2.2.1)

   $ mvn clean install -Dmaven.test.skip=3Dtrue

   # -Dmaven.test.skip=3Dtrue to skip the tests because some of them =
don't work
   # I commented out the uima module in the pom as at revision 958920 it =
did not work
   # add -o to avoid redownloading maven bundles if you allready have =
downloaded them the first time

3. create a key for the machine you are running this on, which you need =
to place in .keystore
   So if this is going to be run on localhost then you need the =
Distinguished name to be localhost

   $ keytool -keystore keystore -alias jetty -genkey -keyalg RSA =
-keysize 2048
   $ mv keystore ~/.keystore # of course if you already have one, then =
watch out here

4. start it
=20
   $ cd org.apache.clerezza.platform.launcher.tdb/target
   $ java -Dorg.wymiwyg.jetty.httpservice.clientauth=3Dwant =
-Dorg.osgi.service.http.secure.enabled=3Dtrue -jar =
org.apache.clerezza.platform.launcher.tdb-0.5-incubating-SNAPSHOT.jar
   # you will end up in a command line interface where you can send a =
number of commands such as
   -> help
   # don't cntr-Z (background) this on OSX, as for some reason the =
command line interface=20
   # then no longer works


5. try it out

  - you should have an http server at http://localhost:8080/
  - you can try logging in with your (non RDFa backed) Web ID at =
https://localhost:8443/dashboard
=20
6. build RDFa support

   use the OSGi enabled module I put together at =
http://github.com/bblfish/java-rdfa

   $ git clone git://github.com/bblfish/java-rdfa.git
   $ cd java-rdfa
  =20
7. install RDFa support

  In the clerezza shell type

  -> start mvn:net.rootdev/java-rdfa-core/0.5-SNAPSHOT
  -> start mvn:net.rootdev/java-rdfa-clerezza/0.5-SNAPSHOT

  It should work now with IDs created with http://webid.myxwiki.org/


TODO
=3D=3D=3D=3D

  The RDFA parsers rely on nu.validator.htmlparser.common and some other =
packages which are not OSGi enabled yet. Reto is currently working on =
improving the access control framework to allow us to create much more =
flexible access control examples. The Scala code probably has bugs as it =
is still fresh.

Note
=3D=3D=3D=3D

 An interesting thing to note about this foaf+ssl implementation, is =
that it is written directly into the java ssl layer. This was Reto's =
idea, and it looks like it could be very helpful, but we still need to =
test it with more examples to see what the limitations may be.

  But in any case, Clerezza is a very interesting framework, and being a =
java programmer, I will try to use this to put together my own =
playground.


  Henry
