DiscussionForumPosting builder

Creates a DiscussionForumPosting with author and comment metadata. The DiscussionForumPosting builder injects @type, validates synchronously, and rejects unknown properties.

Import

// Astro — shown first when Astro is selected
import { DiscussionForumPosting } from '@unschema-graph/astro';

// Svelte 5
import { DiscussionForumPosting } from '@unschema-graph/svelte';

// Core / Node.js
import { DiscussionForumPosting } from '@unschema-graph/core';
import { DiscussionForumPostingSchema } from '@unschema-graph/core';

The DiscussionForumPostingSchema Zod schema is also exported for composition and advanced validation.

TypeScript types

import {
  DiscussionForumPostingSchema,
  type SchemaInput,
  type SchemaOutput,
} from '@unschema-graph/core';

type DiscussionForumPostingInput = SchemaInput<typeof DiscussionForumPostingSchema>;
type DiscussionForumPostingOutput = SchemaOutput<typeof DiscussionForumPostingSchema, 'DiscussionForumPosting'>;

Input properties

Property	Input type	Required	Default / constraints
@id	string	No	non-empty
headline	string	Yes	non-empty
author	string | Person | Organization | EntityReference	Yes	non-empty
datePublished	string | number | Date	Yes	non-empty
text	string	No	—
comment	object | Array	No	—
url	string	No	—

The aliases above remain the exact authority for nested object types. The builder also accepts a validation configuration as its second argument and always returns @type: 'DiscussionForumPosting'.

Minimal example

import { DiscussionForumPosting } from '@unschema-graph/core';

const entity = DiscussionForumPosting({
  "headline": "Structured data patterns",
  "author": "Ada Lovelace",
  "datePublished": "2026-09-29"
});

Output

{
  "@type": "DiscussionForumPosting",
  "headline": "Structured data patterns",
  "author": {
    "@type": "Person",
    "name": "Ada Lovelace"
  },
  "datePublished": "2026-09-29"
}

Common errors

• Passing an unknown property to the strict builder.
• Using source data that is missing a required property.
• Assuming valid Schema.org guarantees a search appearance.

Validation

Use DiscussionForumPosting.safeParse(input) for external data. If Schema.org supports a property that is not modeled yet, validate the entity first and then use withAdditionalProperties(). Never pass invented properties to the strict builder.
