2. Accommodation / Lodging (Range: 200 - 299)

1. Scope & Definition

The Accommodation / Lodging entity category establishes the global identification and routing standards for businesses, properties, and specific units offering commercial, alternative, short-term, or residential lodging.

For modern Artificial Intelligence (AI) systems, Large Language Models (LLMs), and Graph Databases, this category maintains a critical structural distinction: separating the corporate operational entity (Lodging Business) from the physical spatial entity (Accommodation / Place). This distinction is designed to enhance native entity recognition, streamline semantic mapping, and optimize relationship linking in knowledge graphs.

2. Schema.org Alignment

The GSID Accommodation classification architecture maps directly to the global structured data standards defined by Schema.org. Specifically, this entity category is built upon the vocabulary of Schema.org/Accommodation and Schema.org/LodgingBusiness, promoting native semantic interoperability.

3. Structural Syntax

Under the global GSID protocol (XX00.000.000000), the Accommodation / Lodging entity is assigned the three-digit class prefix range 200 to 299.

  • The first digit 2 designates the primary Accommodation / Lodging schema.
  • The subsequent two digits designate the standardized hospitality block and specific subcategory.

Syntax Example: DE45.202.000352

  • DE45: Authorized Registrar (e.g., Germany / example.de)
  • 202: Accommodation Category -> Hotel
  • 000352: Unique lodging establishment serial number
