In this chapter: JSON schemas for cultural events, participant profiles, heritage metadata, media assets, and validation rules. Foundation layer enabling data interoperability.

4.1 Cultural Event Schema

The Cultural Event is the central entity in WIA-UNI-011. Every exchange activity - whether arts exhibition, sports competition, music performance, or heritage project - is represented as a standardized event record.

  "version": "2.0",
  "eventId": "UNI-011-MUSIC-2025-001",
  "eventType": "music",

  },
  "description": {
    "ko": "남북 음악가들이 함께하는 평화 음악 축제",
    "en": "Peace music festival featuring artists from both Koreas"
  },
  "startDate": "2025-06-15T18:00:00+09:00",
  "endDate": "2025-06-17T22:00:00+09:00",
  "location": {

    { "id": "ORG-NK-CULTURE-001", "name": "Ministry of Culture (DPRK)" }
  ],
  "unescoCategory": "intangible",
  "expectedParticipants": 500,
  "tags": ["music", "peace", "unity", "traditional", "modern"]
}

4.2 Participant Schema

Participant records capture information about individuals involved in cultural exchange while respecting privacy and security requirements.

Participant Fields

Field	Type	Privacy Level	Description
participantId	string	Public	Unique identifier
name	i18n	Controlled	Full name in multiple scripts
role	enum	Public	artist, athlete, organizer, audience, etc.
organization	Organization	Public	Affiliated institution
region	enum	Public	south, north, international
specialty	string[]	Public	Areas of expertise/performance
biography	i18n	Public	Professional biography
consentLevel	enum	Private	Data sharing consent level

Privacy-Preserving Design

Participant data uses three-tier access control:

Public: Role, specialty, organization - visible to all
Controlled: Name, biography - visible to authorized parties
Private: Contact info, nationality - strictly restricted

4.3 Heritage Item Schema

Cultural heritage items receive rich metadata following UNESCO standards while documenting regional variations across divided Korea.

Heritage Fields

Field	Type	Required	Description
heritageId	string	Yes	Unique identifier
name	i18n	Yes	Heritage item name with variants
category	enum	Yes	music, dance, craft, food, ritual, architecture
unescoStatus	enum	No	registered, nominated, candidate, local
description	i18n	Yes	Detailed description
historicalContext	i18n	Yes	Historical background
regionalVariations	Variation[]	No	North/South differences
preservationStatus	enum	Yes	excellent, good, fair, endangered, critical
media	MediaAsset[]	No	Documentation media

Regional Variation Documentation

Heritage items often have different names, practices, or preservation states in North and South Korea. WIA-UNI-011 explicitly documents these variations:

{
  "heritageId": "HER-KR-MUSIC-001",
  "name": {
    "ko": "아리랑",
    "en": "Arirang",
    "ko-north": "아리랑",
    "hanja": "阿里郞"
  },
  "category": "music",
  "unescoStatus": "registered",
  "regionalVariations": [
    {
      "region": "south",
      "localName": "정선아리랑",
      "characteristics": "Slower tempo, unique melodic structure",
      "preservationStatus": "excellent"
    },
    {
      "region": "north",
      "localName": "평양아리랑",
      "characteristics": "Faster tempo, orchestral arrangements",
      "preservationStatus": "excellent"
    }
  ]
}

4.4 Media Asset Schema

Cultural exchange generates massive amounts of media. Proper metadata ensures these assets remain discoverable, contextual, and preserved long-term.

Media Asset Fields

Field	Type	Required	Description
assetId	string	Yes	Unique identifier
type	enum	Yes	photo, video, audio, document, 3d
title	i18n	Yes	Asset title
description	i18n	No	Detailed description
creator	string	Yes	Creator/photographer/videographer
created	ISO 8601	Yes	Creation date and time
license	License	Yes	Usage rights and restrictions
file	File	Yes	File details (URL, format, size, checksum)
relatedEvent	string	No	Event ID if applicable
tags	string[]	No	Discovery tags

Rights Management

Media assets include detailed licensing information enabling proper usage tracking and rights management:

Creative Commons: CC0, CC-BY, CC-BY-SA, CC-BY-NC, CC-BY-ND
Public Domain: Public domain dedication for historical materials
Rights Reserved: All rights reserved with permission required
Government Work: Government-created content with special status

4.5 Multilingual Data Structures

WIA-UNI-011 uses the i18n (internationalization) type for all user-facing text. This structure supports multiple languages and scripts:

{
  "title": {
    "ko": "한글 제목",
    "ko-north": "조선말 제목",
    "en": "English Title",
    "zh": "中文标题",
    "ja": "日本語タイトル"
  }
}

Language Codes

ko - Korean (South Korean standard)
ko-north - Korean (North Korean variation)
en - English
hanja - Chinese characters (Hanja)
zh, ja, ru - Other languages as needed

4.6 Validation Rules

All WIA-UNI-011 data must pass validation before being accepted into systems. Validation ensures data quality, consistency, and interoperability.

Standard Validation Rules

All required fields must be present
Dates must be valid ISO 8601 format with timezone
Coordinates must be within valid latitude/longitude ranges
Enum values must match allowed options
At least one language (ko or en) required for i18n fields
References (eventId, organizationId) must resolve to valid entities
File checksums must match actual file content

4.7 Data Migration Strategy

Organizations with existing cultural databases can migrate to WIA-UNI-011 format using provided conversion tools:

Export existing data in CSV, JSON, or Excel format
Map fields from legacy schema to WIA-UNI-011 schema
Enrich data with missing required fields
Validate using WIA-UNI-011 validation tools
Import into WIA-UNI-011 compliant systems
