Start by creating a local directory for the schemas.
mkdir /scratch/slicSchemas
Next set the GDML_SCHEMA_DIR environment variable to point to the directory. The init_ilcsoft.sh script itself sets GDML_SCHEMA_DIR, so this command must be run after init_ilcsoft.sh (or replace the corresponding line in init_ilcsoft.sh).
export GDML_SCHEMA_DIR=/scratch/slicSchemas
SLIC also searches automatically in the current directory for schemas.
The entity resolver in GDML should find the schemas if the structure has been flattened (all .xsd files in the local directory).
It should also be able to find the schemas when the path component of the URL is preserved, i.e. ./schemas/lcdd/1.0/lcdd.xsd.
Copying LCDD schemas from ilcinstall build
The GDML & LCDD schemas are already present in the ilcinstall installation, so they can be directly copied into your local directory.
. $ILCSOFT/init_ilcsoft.sh cd /scratch/slicSchemas cp $G4INSTALL/source/persistency/gdml/schema/*.xsd . cd $LCDD/schemas/lcdd/1.0/*.xsd .
The above instructions assume that SLIC has already been successfully installed with ilcinstall.
Getting the LCDD schemas from SVN
To copy the schemas into a local directory without using any ilcinstall installation, execute the following commands.
cd /scratch svn co svn://svn.freehep.org/lcdet/projects/lcdd/trunk lcdd cp lcdd/schemas/*/*/*.xsd slicSchemas
If you want to keep the schema directory structure, use this command instead.
cd lcdd cp -R schemas /scratch/slicSchemas
The LCDD schemas can also be found online at http://www.lcsim.org/schemas/lcdd/1.0/.
Downloading the GDML schemas
Go into the local schema directory.
cd /scratch/slicSchemas
Now create a file schemaFiles.txt with the following contents in it. (Just copy and paste into the file in your editor and then save it.)
gdml.xsd gdml_core.xsd gdml_define.xsd gdml_extensions.xsd gdml_materials.xsd gdml_parameterised.xsd gdml_replicas.xsd gdml_solids.xsd
Then execute the following command to pull the schemas from the standard URL location.
wget -i schemaFiles.txt -B 'http://service-spi.web.cern.ch/service-spi/app/releases/GDML/schema/'
Now you should see all of the GDML XSD files in the local directory.
