Module local

Language-tagged shape model and factories.

Defines shapes and factories for validating language-tagged string values, mapping JSON-LD language maps to RDF 1.1 language-tagged strings.

Defining Language-Tagged Shapes

Single-valued maps hold one string per language tag; multi-valued maps hold arrays:

import { local, locals } from '@metreeca/blue';

const label = local();                                   // wildcard: { "*": "" }
const title = local({ minLength: 1, maxLength: 200 });   // constrained
const description = local({ languageIn: ["en", "it"] }); // language-restricted

const keywords = locals();                               // wildcard: { "*": [""] }
const tags = locals({ languageIn: ["en"] });             // English only

Using in Resource Shapes

import { resource, required, optional, local, locals } from '@metreeca/blue';

const Article = resource({
  title: required(local({ minLength: 1 })),
  abstract: optional(local()),
  keywords: optional(locals({ languageIn: ["en", "fr", "de"] }))
});
