Weaviate Semantic Schema Repo with Ontologies

In this repo you can find a set of commonly used semantic schemas like schema.org

Within Weaviate, you can use these schema's to define things or actions.

You can find more info in the Weaviate Repo

Note: The available schemas in Weaviate are based on schema.org and cover already. In case you have a valuable schema that you want to share, feel free to issue a pull request

Schema types

Weaviate knows two types of schemas:

1. Thing schemas
2. Action schemas

The Thing schemas are used to define actual things. The Action schemas are used to define actions. These actions will also be made available to the things. For example, to execute a command.

Creating a custom schema

This repo contains examples of ready to use schemas. But you can create your own schema.

Template example:

{
	"@context": "http://schema.org", // an example context
	"version": "x.x.x", // semver version number of this schema (www.semver.org)
	"type": "thing", // thing or action
	"name": "schema.org - Thing",
	"maintainer": "yourfriends@weaviate.com", // should be email
	"classes": [{
		"class": "Thing",
		"description": "This is a Thing",
		"properties": [{
			"name": "owner",
			"@dataType": ["Person"], // if a cross-reference it has a capital (= Class) otherwise it is a value*
			"description": "Owner of the thing.",
			"keywords": [{
				"name": "Keyword"
				"weight": 0.9
			}]
		}],
		"keywords": [{
			"name": "Keyword"
			"weight": 0.9
		}]
	}]
}

* Notes:

• The value in the @dataType array should contain on of the following values: any uppercase starting word (like Person) being a cross-reference, string, int, number, boolean or date.
• Every property with a certain name across all schema's should contain either a cross-reference or one of the values. For example, in this example the property owner in another class can only contain a data type starting with a capital (like Person or Company).
• Different data types can not be combined in the array
• Weaviate validates the schemas when initializing, giving a detailed error when some of the requirements mentioned above are not met

Note: You can use the existing schemas as templates or examples

Generators

Generators are use to create custom schemas. They should be run from the ./generators dir of the repo. Like: $ cd generators && python generate_schema.org.py. The schema.org generator generate_schema.org.py needs one argument, the semver version of the schema you want to generate, like: python generate_schema.org.py 1.0.0.
