Linked Data by Zürich Statistical Office

Zürich Statistical Office collects and publishes statistical information from all areas of life. That includes demographics, economy, construction, residency and politics. Corresponding datasets are publised as Linked Data.

These tutorials show how to work with Linked Data. They demonstrate how to query data published by city of Zurich. We recommend them to:

Explore datasets from Zürich Statistical Office
Retrieve data slices about demographics, real estate and economics
Visualize these data slices

SPARQL endpoint

If you are familiar with SPARQL, you can execute your queries here: https://ld.stadt-zuerich.ch/sparql/. Our tutorials show how to work with SPAQRL directly in python.

Install

Locally

To setup the project locally:

python3 -m venv venv create virtual environment
source venv/bin/activate to activate venv on Linux or venv\Scripts\activate.bat to activate venv on Windows
pip install -r requirements.txt install dependencies
python -m ipykernel install --user --name=ssz add python kernel to jupyter
jupyter sparqlkernel install --user ssz add SPARQL kernel to jupyter
jupyter notebook start a server

For more details on how to setup jupyer notebook in a virtual environment, look here For more details on istalling SPARQL kernel, look here

Remotely

You can execute data exploration notebooks in Google Colab environment. To run it in Colab, you will need to install all dependencies. First, import requirements.txt to your workspace. Then install them. You can do it by running (in colab): !pip install -r requirements.txt

Explore

We provide tutorials on data model, and data exploration.

Use data exploration tutorials to:

learn how to work with SPARQL in python
find demoraphics, economics, or real estate data
learn about Zurich over time

Use data model tutorial if:

you want to find other datasets about Zurich
you don't know how to formulate queries to access it

Data model

Here we explain the logic behind the Zürich's Linked Data model. This tutorial will guide you through the data structure. It will show you available datasets, and the shape they take. You will find there queries explaining data structure, and available dimensions.

The tutorials are:

Data model

For this tutorial, choose kernel SPARQL.

Data exploration

These tutorials explore available datasets. You will see how to query, preprocess and visualize Zurich datasets. You will find there queries for specific observations.

Available tutorials are:

For these tutorials, choose kernel ssz.
