HowTo - Lens2Northwind (Lens2OData + OData2SPARQL + RDF4J + northwind data) Docker container Usage

lens2odata makes query answering over OData and Linked-Data far easier, using a graphical experience for composing even complex queries, and is available as a Docker image, using the well known Northwind database as an example.

Assuming you have a working docker installation:

1. Pull the inova8/lens2northwind docker image:

$ docker pull inova8/lens2northwind

2. Run the inova8/lens2northwind docker image, publishing itself on port 8080:

$ docker run --publish 8080:8080 inova8/lens2northwind

3. Verify the Lens2Northwind docker container is accessible by loading the RDF4J Workbench on URL http://localhost:8080/rdf4j-workbench :

4. Select the northwind repository from the list available and select the Explore -> Query option from the left frame to execute a SPARQL query against the available Northwind RDF data:

5. Clicking the execute button from the previous step, with suitable RDF query returns result set:

6. Access the Quorum360’s Lens2OData user interface by opening the URL at http://localhost:8080/lens2odata/ with uid/pwd of lens2odata/lens2odata:

7. Click the Submit button to load the Northwind RDF data (apartments):

8. This loads the home page for accessing the Northwind RDF data:

9. You are now ready to query, search, explore and navigate through these apartments graphs:
