Load and use DCAT-US 3.0 as a schema ontology in semantic middleware.
Our organization is testing and evaluating semantic middleware and taxonomy management tools. We need to be able to load DCAT-US 3.0 and use it as a schema ontology to structure our organization's metadata.
Problem Statement:
The tools we are evaluating accept linked data formats including but not limited to: .ttl, jsonld, rdf/json, but we have been unable to validate or load the DCAT-US 3.0 schema files. Located here: context/dcat-us-3.0.jsonld, jsonschema/dcat_us_3.0.0_schema.json, or here jsonschema/definitions. Since there is no .ttl file of the ontology that doesn't include shacl, we're unable to try that alternative serialization to complete the task.
The stakeholders include the following:
Development Team responsible for testing and evaluating the tools for taxonomy management.
Early adopters whose use cases are part of the tool's evaluation process.
Intended Uses / Use Cases
Load and view DCAT-US 3.0 schema within the taxonomy management tool (semantic middleware).
Extend and connect concepts from the schema using the interface of the taxonomy management tool.
Existing Approaches
We have been unable to load the files as they are shared in the locations listed above in the problem statement into our semantic middleware tooling. The error logs haven't provided sufficient information to determine what the problem is, so took the step of troubleshooting by loading the JSON-LD files into a few code validators for the purpose of identifying any problems we could fix before trying to load them again. The validators we used were: https://issemantic.net/schema-markup-validator, https://validator.schema.org/. If this is a lack of skill on the team, additional documentation on how to assess and use the JSON-LD files would also be appreciated.
