Lab: Getting started with VSCode, Python and RDFlib
Lab 1: Getting started with Pycharm, Python and RDFlib
Installation of and introduction to Python, Pycharm, Pip and RDFlib.
PyCharm is a Python Integrated Development Environment (IDE) that can be used for writing python code.
Pip is used to easily install additional python packages for your coding environment.
RDFLib is a Python package for working with RDF. With this we can create RDF graphs, parse and serialize RDF, perform SPARQL queries on graphs and more.
If needed here is an introduction of how to create projects and python files in Pycharm Eclipse IDE - Tutorial by jetbrains.com.
RDFLib Documentation- Todays focus are the following:
Additional recommended in depth documentation:
Useful code examples can be found of this wiki.
Relevant RDFlib classes/interfaces (and methods)
- Graph (add, remove, serialize)
- RDF, FOAF
All RDFlib modules can be found here Browser search (often Ctrl-F) is useful here to find the module that you want.
You likely already have Python installed on your computer (it comes with MAC for instance). To find out, type 'python' in the commandline on windows or type 'python --version' in the terminal on your MAC. If you don't already have Python, download and install the Python for your operative system here. We recommend downloading the most recent version.
If you are already using a different Python IDE than Pycharm that you are comfortable with, then you are free to use that program instead.
Otherwise Download and Install the free and open source Pycharm Community IDE here.
Pip On Windows: Download pip here: https://bootstrap.pypa.io/get-pip.py. (Right click on this link and click "Save link as". You can save it to you desktop or somewhere else if you would like)
Open a command prompt and navigate to the folder containing get-pip.py. (e.g enter 'cd Desktop' to get to the desktop)
Now run the following command in the promt 'python get-pip.py'
Pip On Mac:
Open the terminal and first run: 'curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py'
Now run this: 'python get-pip.py'
Using the Pycharm terminal, install RDFlib by simply entering: pip install rdflib
Start Pycharm and create a new project with a new .py file.
Create a python program that creates a single triple and writes it out. Use the Classes/interfaces and methods listed above.
If you have more time...
If you have more time you can continue extending your graph with some of the stuff from lab 2: "Cade Tracy lives in 1516 Henry Street, Berkeley, California 94709, USA. He has a B.Sc. in biology from the University of California, Berkeley from 2011. His interests include birds, ecology, the environment, photography and travelling. He has visited Canada and France." Try to use as many different methods as possible to create the triples.
