8. Service (Range: 800 - 899)

1. Scope & Definition

The Service entity category defines the global identification, cataloging, and routing standards for intangible provisions, professional solutions, commercial tasks, and utility functions.

From an Enterprise Data Architecture perspective, a Service represents an intangible value proposition offered by an executing party (linking to an Organization [Core Entity 5] or Person [Core Entity 4]) to a consumer. Unlike physical products, services are action-based or access-based.

To promote clean machine comprehension, the GSID protocol distinguishes between highly regulated sectors with native Schema.org classes (e.g., financial accounts or medical treatments) and generic business-to-business or local trade services which are mapped under the primary Service class but categorized semantically using specific GSID blocks.

Identifiers in this range are designed to route to digital service profiles, structural pricing frameworks, and corporate service catalogs within the registrar's network.

2. Schema.org Alignment

The GSID Service classification architecture maps directly to the global structured data standards defined by Schema.org. Highly structured blocks utilize native subclasses of Schema.org/Service, such as FinancialProduct or MedicalService. Industry-specific commercial blocks instantiate the generic Schema.org/Service entity and are classified via the serviceType property, promoting native semantic interoperability.

3. Structural Syntax

Under the global GSID protocol (XX00.000.000000), the Service entity is assigned the three-digit class prefix range 800 to 899.

  • The first digit 8 designates the primary Service schema.
  • The subsequent two digits designate the standardized thematic block and specific operational service class.

Syntax Example: US45.811.000789

  • US45: Authorized Registrar (e.g., United States)
  • 811: Service Category -> BankAccount (e.g., A corporate checking account program)
  • 000789: Unique service portfolio registry serial number
