A template repository for creating demos for visualizing RDF semantic graphs alongside 3D City models using:
- UD-Viz as a frontend web application for urban data visualization
- In particular the SPARQL module is used to visualize semantic urban data in the form of RDF
- Strabon RDF Store an RDF-Store for storing and serving geospatial semantic graph data in the form of RDF
- PostGIS a geospatial database extension of PostgreSQL used here as a backend database for Strabon
To begin create a new Github repository using this template:
Once generated, use the new repository can be cloned:
git clone [your new repository URL]
To configure the demo and the components that support it edit the .env file to be launched with docker-compose. By default the following ports are used by the following services:
- 8996:
PostGIS - 8997:
Strabon - 8998:
UD-Viz
The following sections will describe how to configure this file for each component.
First, build the PostGIS, Strabon, and UD-Viz docker images and run their containers:
docker-compose up
Note: Make sure to set the sparqlModule/url port in the ./ud-viz-context/config.json file to the same port for the Strabon container declared in the .env file. If these ports are ever changed after building the images, the UD-Viz image must be rebuilt:
docker-compose rm udviz
docker-compose build udviz
All files in the data folder are copied into the Strabon container at /data. To upload these files into Strabon to be used by the sparqlModule:
- Open a web browser and navigate to
localhost:8997/strabon - From the left menu, click Explore/Modify operations then Store
- Copy and paste the local path of each file in the data folder as
file:///data/[file to upload]into the URI Input field and click Store from URI⚠️ You may be asked to enter the Strabon administrative credentials here. However, these credentials currently cannot be changed from the.envfile. See issue #1.
Now the demo is ready and can be accessed from localhost:8998
