To run this example, you need an AWS account with permission to create resources such as a Neptune cluster.

Create Neptune resources using AWS CloudFormation. Download a copy of the CloudFormation template (cfn/neptune_ontology_main.yml) from this repository. Then complete the following steps:

1. On the AWS CloudFormation console, choose Create stack.
2. Choose With new resources (standard).
3. Select Upload a template file.
4. Choose Choose file to upload the local copy of the template that you downloaded. The name of the file is Neptune_ontology_main.yml.
5. Choose Next.
6. Enter a stack name of your choosing.
7. In the Parameters section, use defaults for the remaining parameters.
8. Choose Next.
9. Continue through the remaining sections.
10. Read and select the check boxes in the Capabilities section.
11. Choose Create stack.
12. When the stack is complete, navigate to the Outputs section and follow the link for the output NeptuneSagemakerNotebook.

This opens in your browser the Jupyter files view. There are two notebooks available:

• Neptune_Multimodel.ipynb, demonstrating the multimodel example
• Neptune_Ontology_Example.ipynb, demonstrating the ontology example in https://aws.amazon.com/blogs/database/model-driven-graphs-using-owl-in-amazon-neptune.

We encourage you to review the stack with your security team prior to using it in a production environment.

To run the ontology example discussed in the blog https://aws.amazon.com/blogs/database/model-driven-graphs-using-owl-in-amazon-neptune, open the Neptune_Ontology_Example.ipynb notebook; then follow the steps!

To run the multimodel example discussed in the blog , open the Neptune_Multimodel.ipynb notebook and follow the steps.

The template creates Neptune cluster resources, a SageMaker notebook (Neptune Workbench), an S3 bucket, plus additional resources. The Neptune cluster and SageMaker notebook incur costs. Refer to the Neptune pricing guide https://aws.amazon.com/neptune/pricing/ for pricing.

If you’re done with the solution and wish to avoid future charges, delete the CloudFormation stack.
