A python library binding of the c++ library tada-hdt-entity

Not that to install pytada-hdt-entity, you don't need to perform the swig build as this is already done by the authors. All you need is the files in this repository and the depedencies.

1. hdt-cpp
2. tabular_parser
3. easy_logger
4. tada_hdt_entity

pip install git+https://github.com/oeg-upm/pytada-hdt-entity.git

sh scripts/compile.sh  

These are included in compile.sh

• For debian and ubuntu: install-script
• For other linux distro and macOS: use the debian script but update it with the equivalent command to install prerequisite packages

1. You need to setup the following environment variables: You might not need this in the newer versions
   • export project_dir='.' (or the directory of the c++ source code)
   • export LC_ALL=en_US.UTF-8 (needed for mac)
   • export LANG=en_US.UTF-8 (needed for mac)
2. Generate the interface files:
   • invoke copyc (only if you need to copy the source files to the current folder. If you copy the c++ files to this directory, you do not need to do it). Note that you need to setup the environment variable project_dir to point to the tada-hdt-entity directory.
3. Copy the python files into the package:
   • invoke copypy Copy the generated python files to tada_hdt_entity

1. Update setup.py with the new version of the library

1. SWIG (to handle .i files)
2. HDT lib
3. tabular_parser lib
4. easy_logger lib
5. tada_hdt_entity lib

brew install swig

1. Generate test.hdt.
   1. cd pytada-hdt-entity/test_files
   2. ~/hdt-cpp/libhdt/tools/rdf2hdt test.ttl test.hdt (change the location to point to the hdt-cpp).
2. Run test cases.
   1. Return back to the pytada-hdt-entity folder cd ...
   2. python -m unittest discover.
