The FCC Event Data Model.
The Data Model uses PODIO. On lxplus the PODIO installation is picked up by the init.sh script.
If you are unable to use this central installation you'll have to compile, install and setup the environment for PODIO.
Please report any feature requests and issues at this JIRA for the component DataModel.
Browse the API documentation created with Doxygen at http://fccsw.web.cern.ch/fccsw/fcc-edm/index.html.
If you are on lxplus, all the necessary software is preinstalled.
On Mac OS or Ubuntu, you need to install the following software.
https://github.com/HEP-FCC/podio
Before compiling or using:
-
If on Mac OS, Ubuntu or using a custom PODIO installation, set up the PODIO environment.
-
Set up the FCC-EDM environment:
source ./init.sh
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=$FCCEDM ..
make -j 4 install
Rudimentary tests that do write and read can be run with
make test
Make sure that the ROOT dictionaries are in the LD_LIBRARY_PATH. This is automatically done when you install, otherwise you may need to update the path accordingly.
The examples are located in the examples directory. This command writes an example.root file:
$FCCEDM/bin/fccedm-write
That file can then be read with
$FCCEDM/bin/fccedm-read
