+====== Reconstruction Software Page ======
+===== Overview =====
+Technology
+The FIRST experiment reconstruction code design must cope with several different constraints
+  - Existing sub-detectors code is written in different languages
+  - Framework is not existent
+  - MC simulation is done in different languages
+In order to put together everythin a 'modular' approach is mandatory. **C++** together with **design pattern strategy** together with **python** seems the best way to go.
+In order to avoid to start writing from scratch the Framework Code, we have looked around in the HEP community and find out that there's a very good candidate as a framework for Particle Physics experiment code developement: [[http://proj-gaudi.web.cern.ch/proj-gaudi/|Gaudi]]. Gaudi provides all the tools needed in order to build an application, higly modular and easily configurable, for I/O and data handling.
+Tools/Code external links
+  - SVN
+  - CMT [[http://www.cmtsite.org|CMT web site]]
+  - Gaudi [[http://proj-gaudi.web.cern.ch/proj-gaudi/|Gaudi framework]]
+  - ROOT [[http://root.cern.ch | web page]]
+  - Python
+===== Framework =====
+  * Using Gaudi Framework
+==== Gaudi installation ====
+  * SLC4 32 bit
+  * Mac OSX
+For detailed instructions on how to compile/run please follow the [[http://wiki.infn.it/strutture/lnf/dr/tps/first/recosoft/gaudiinstall/home|link]]
+==== Event Model ====
+The event model is being implemented using GaudiObjDesc (GOD) [[https://lhcb-comp.web.cern.ch/lhcb-comp/Frameworks/DataDictionary/|link]] that has been developed inside LHCb collaboration. In order to get it you can
+  * use getpack (after having sourced the LbLogin.*sh script and SetupProject Gaudi)
+  * access directly the LHCb sv nrepository [[|here]]
+**A simple hack is needed to dump with proper namespace :: go to the godII.py script and replace LHCb with First until I understand how to pass options in the requirements**
+===== Dexter Application =====
+The Dexter (Data EXtraction and Trigger and Event Reconstruction) application is currently being develeoped using the Gaudi Framework.
+The repository can be found [[https://svn.cern.ch/reps/firstrec|here]] for users that have a cern account.
+Compiling and running is currently being tested only under slc4.
+=== Check out the Project ===
+In order to check out the Whole project you need to have svn installed on your PC.
+<code>
+svn co -N svn+ssh://svn.cern.ch/reps/firstrec
+</code>
+=== SLC4 ===
+  * After SetupProject and other blabla...
+  * Issue a global make
+<code>
+cmt br -global cmt config
+cmt br -global cmt make
+</code>
