The BIAN Service Landscape is a reference structure that categorizes and organizes BIAN Service Domains for ease of access. Different criteria can be used to classify and organize Service Domains that would result in different layouts of the standard set of BIAN Service Domains. BIAN uses a ‘primary’ Service Landscape view based on agreed categorizations that have been refined in use by the BIAN membership.

The BIAN Metamodel is a detailed and comprehensive (UML) model that defines all the BIAN design structures — it is fully documented elsewhere in its own guide (The BIAN Metamodel). The Metamodel has three elements that capture the design of the BIAN Service Landscape.

  1. Business Area — is the highest-level classification. A business area groups together a broad set of business capacities. For the BIAN Service Landscape they are defined to be aspects of business activity that have similar supporting application and information-specific needs.
  2. Business Domain — at the next level, business domains define a coherent collection of capacities within the broader business area. In the BIAN Service Landscape the business domains are associated with skills and knowledge recognizable in the banking business.
  3. Service Domain — is the finest level of partitioning, each defining unique and discrete business capacities. The Service Domains are the ‘elemental building blocks’ of a service landscape.

The Service Domain relates to generic capacities that do not vary in their scope, but the definitions of the Business Domain and Business Area are classifications that are specific to a particular Service Landscape layout. The Service Landscape layout can be varied depending on use.

SL 8.0 – Q3 2019

  • Substantial updates to the BIAN Metamodel and content
  • Significant change in the definition and mapping of Action Terms to the Service Domain Functional Patterns, to improve the mapping to REST
  • Steep increase in the documented Business Capabilities, Business Scenarios and Service Domain descriptions, notably Control Records and Service Operations
  • The model is being documented in BiZZdesign, BIAN’s new repository, which currently includes the Business Capability Model, the Business Scenario Model with Service Domain descriptions and the Business Object Model
  • The BIAN Metamodel Architectural concepts are expressed in version 8.0 in the ArchiMate 3.0 architecture modelling language. This gives Banking Enterprise Architects who are familiar with the ArchiMate Language a more precise understanding of the BIAN defined metamodel elements
  • The BIAN Reference Architecture is expressed in a combination of ArchiMate and UML

The following timeline shows what the completion of the BIAN Service Landscape (SL) v3.0 — v8.0 contains and in what year the assets will be published.
