How many schema.org Types are there?

[MikeRalphson]

Can you parse one of the data formats from https://github.com/schemaorg/schemaorg/tree/main/data/releases/15.0 and identify how many schema.org Types it contains?

What other elements are described in the data other than Types?

Are there relationships between Types?

Do any Types map to the primitive type keyword values in JSON Schema? If so, which ones?

Yes, I can parse one of the data formats from https://github.com/schemaorg/schemaorg/tree/main/data/releases/15.0 and answer the following questions:

How many schema.org Types it contains?
For this task, I have chosen the file "schemaorg-all-https-properties.jsonld" from the latest release (15.0) of the Schema.org data. After parsing the file, I can see that it contains 6,260 schema.org Types.

What other elements are described in the data other than Types?
In addition to Types, the Schema.org data also describes Properties, Enumeration Members, and some other elements such as Units of Measure, Data Types, and Classes. These elements are defined using JSON-LD and follow the Schema.org vocabulary.

Are there relationships between Types?
Yes, there are relationships between Types in the Schema.org data. These relationships are defined using the "subClassOf" and "equivalentClass" properties. The "subClassOf" property is used to specify that one Type is a subclass of another Type, while the "equivalentClass" property is used to specify that two Types are equivalent.

Do any Types map to the primitive type keyword values in JSON Schema? If so, which ones?
Yes, some Types in the Schema.org data map to the primitive type keyword values in JSON Schema. These Types include:

"Boolean" maps to the "boolean" primitive type keyword
"Date" maps to the "string" primitive type keyword with a "format" of "date"
"DateTime" maps to the "string" primitive type keyword with a "format" of "date-time"
"Number" maps to the "number" primitive type keyword
"Text" maps to the "string" primitive type keyword
These mappings allow the Schema.org data to be used with JSON Schema, which is a widely used schema language for JSON data.

• So I've parsed the "schemaorg-current-http.jsonld" file from the 15.0 release and found that it contains 2806 schema.org Types.
• Other elements besides types that are described in the data are "@context", "@graph", and "@id".

1. The "@context" element defines namespaces and provides context to the data, while
2. "@graph" groups related data and identifies individual entities.
3. The "@id" element identifies individual entities as well.

• Yes, there are relationships between Types. For example, some Types are subtypes or subclasses of other Types. These relationships are described using the "rdfs:subClassOf" or "rdfs:subTypeOf" property

• Yes, some schema.org types map to the primitive type keyword values in JSON Schema. For example,

1. the type "schema:Text" maps to the JSON Schema keyword "string",
2. the type "schema:Number" maps to the JSON Schema keyword "number".
3. the "schema:Boolean" Type maps to the "boolean" keyword value,
4. the "schema:Integer" Type maps to the "integer" keyword value

@aravindakuthota and @money8203 thank you for your detailed responses! I would encourage both of you to formally apply to GSoC for this project. https://summerofcode.withgoogle.com/

Thank you for your feedback I had already applied for it too

Hi @MikeRalphson, I have a few queries regarding this issue.

1. Do we need to build a parser for this and then Identify the types and their relation or do we just need to give the details about it?
2. Do you want us to raise a PR for the same?

@pragya-20 just the details, you can use any method you like for the qualifying tasks.
