Major refactor, revises workflow
Old workflow:

• Upload resource to s3, packaging in metadata to use when creating RDF
• Read resource from s3, parse metadata and put TTL file somewhere to register it as a dataset

New workflow:

• Utilize custom extension for CKAN to handle AORC datasets
• Collect metadata during the data processing phase, package this into a JSON object
• Send POST request to CKAN instance with extensions enabled
• Allow CKAN to handle the dataset URI creation and cataloguing

For now, the CKAN extensions utilized live here. Plan to move them and test integration with existing Dewberry CKAN instance
