This project provides a reusable set of libraries for the JVM with clear dependencies to other open source libraries for the openLCA framework. Since version version 1.4 the openLCA application is built on top of these components.

• olca-core: the openLCA kernel with the openLCA model, the database layer, LCA calculation, etc.
• olca-ecospold-1: an API for reading and writing EcoSpold 01 files.
• olca-ecospold-2: an API for reading and writing EcoSpold 02 files.
• olca-eigen: a JNI wrapper for the high performance math libraries Eigen and OpenBLAS.
• olca-formula: the openLCA formula iterpreter
• olca-geo: provides tools for regionalized LCIA calculation based on shapefiles and KML definitions
• olca-ilcd: an API for reading and writing ILCD data sets with an implementation of the ILCD network interface
• olca-io: the import-export API of openLCA
• olca-simapro-csv: an API for reading and writing SimaPro CSV files.

To compile the modules you need to have a Java Development Kit >= 7 and Maven installed. Download the repository, navigate to the root folder and type the following command in your console:

mvn install

This will build the modules from source and install them into your local Maven repository. If the build failes because of failing tests you can skip the tests via:

mvn install -DskipTests=true
