Fundamentals
Introduction
The Global Risks Index (GRIx) is an advanced framework designed to standardize and integrate risk data across multiple domains, including environmental, financial, geopolitical, cybersecurity, and social sectors. GRIx leverages the Microsoft Common Data Model (CDM) to achieve seamless data integration, interoperability, and scalability. This section delves into the technical details of how GRIx utilizes CDM, focusing on JSON documents, the corpus structure, version management, standard definition documents, and the import mechanisms essential for maintaining a robust and flexible data architecture. Additionally, we cover significant areas of hazards, vulnerabilities, exposure, risks, and advanced and complex risk modeling.
JSON Documents in GRIx
Overview
In GRIx, the shape and meaning of CDM entities, as well as the arrangement of data within folders, are expressed through JSON structures. These JSON documents define the schemas and validation rules that govern how data is organized and interpreted within the GRIx framework. The CDM language serves as the schema for describing and validating the allowable JSON objects contained within these documents.
Structure of JSON Documents
Each JSON document in GRIx adheres to the CDM language schema, ensuring consistency and validity across all data definitions. The primary types of JSON documents utilized by GRIx include:
Entity Schemas (
*.cdm.json): Define the structure and attributes of GRIx-specific risk entities.Manifest Files (
*.manifest.cdm.json): Describe the organization of data within CDM folders, including references to entity schemas and data partition locations.
Example: RiskEntity Schema
Below is an example of a GRIx-specific JSON schema defining the RiskEntity:
This schema defines the RiskEntity with attributes such as RiskEntityID, Name, Description, and relationships to other entities like RiskCategory, Geography, Sector, and Asset.
The Corpus in GRIx
Overview
The corpus in GRIx represents the top-level object within the CDM object model. It maintains a hierarchy of folders containing related and interlinked JSON documents that define data schemas and metadata essential for GRIx operations.
Corpus Structure
GRIx organizes its data within a structured corpus that mirrors its risk management domains. The corpus paths facilitate referencing and linking data across different entities and schemas.
Example Corpus Path Structure:
Corpus Paths
A corpus path defines the location and reference to objects within the corpus. It follows the structure:
storage: Indicates the storage adapter (e.g.,
local:,cdm:,adls:).folderPath: Hierarchical folders categorizing different risk domains and subdomains.
documentName: Name of the JSON document defining entities or schemas.
definitionName: Specific entity or object defined within the document.
subObject: Nested objects or attributes within the entity.
Example Corpus Path:
This path references a sub-object within the RiskEntity defined in the TemperatureAnomaly.cdm.json document located under the Climate_Risks folder in the local storage adapter.
Version Information
Overview
Maintaining version consistency is crucial for the integrity and backward compatibility of GRIx schemas. Both schema definition files (*.cdm.json) and manifest files (*.manifest.cdm.json) begin with references to the JSON schema document that validates their content and the CDM object model version number used.
Schema and Manifest Versioning
Version Declaration Example:
jsonSchemaSemanticVersion: Specifies the version of the JSON schema used for validation.
objectModelVersion: Indicates the version of the CDM object model that validates, loads, and shapes the objects described in the document.
Backward Compatibility
GRIx adheres to CDM’s versioning guidelines to ensure:
Minor and Patch Versions: Maintain backward compatibility, allowing newer versions to read older schema definitions without issues.
Major Versions: Introduce significant changes that may require migration or adaptation.
Example:
Version 1.0: Initial release of GRIx schemas.
Version 1.1: Minor updates adding new attributes to existing entities.
Version 2.0: Major overhaul introducing new risk domains and entities.
By following this versioning strategy, GRIx ensures that updates and enhancements do not disrupt existing integrations and workflows.
Common and Standard Definition Documents
GRIx leverages a set of common and standard definition documents to define and validate its data schemas. These documents are integral to maintaining consistency and interoperability within the CDM framework.
Key Definition Documents
Document
Contents
primitives.cdm.json
Root definitions of most objects and types. Used internally by GRIx for interpreting other objects.
meanings.cdm.json
Shared semantic meanings for describing metadata, such as definitions for common terms and units of measurement used across various entities.
foundations.cdm.json
Building blocks of standards, defining important concepts like lists of localized text, lookup tables, and foreign keys within GRIx’s data schemas.
commonDefinitions.cdm.json
Contains standardized definitions specific to GRIx, such as RiskCategory, RiskFactor, and other foundational entities unique to global risk management.
grixRiskEntities.cdm.json
Defines core GRIx risk entities like RiskEntity, RiskIndicator, RiskScore, and their attributes and relationships.
hazardDefinitions.cdm.json
Defines various types of hazards relevant to GRIx, including natural and man-made hazards within the water-health-food-energy nexus.
vulnerabilityDefinitions.cdm.json
Defines vulnerabilities across different sectors, including infrastructure weaknesses and socio-economic susceptibilities.
exposureDefinitions.cdm.json
Defines exposure metrics and contexts, detailing how assets and populations are exposed to various hazards.
riskDefinitions.cdm.json
Defines risk entities, categories, and mitigation measures, integrating multiple risk dimensions like financial, political, systemic, health, and climate risks.
Example: commonDefinitions.cdm.json
This document defines the RiskCategory and RiskFactor entities, providing a standardized foundation for categorizing and analyzing risks within GRIx.
Imports and Monikers in GRIx
Imports allow GRIx to reference and utilize definitions from other CDM documents, promoting reusability and modularity. Monikers are aliases assigned to imported documents to manage naming conflicts and facilitate clearer references.
Importing Documents
GRIx imports standard and custom definition documents to build its comprehensive risk management schema.
Example Import Statement:
Using Monikers
When importing documents that may have naming conflicts, GRIx assigns monikers to differentiate between similar entities from different sources.
Example Import with Moniker:
Referencing Entities with Monikers:
common/RiskCategory: ReferencesRiskCategoryfromcommonDefinitions.cdm.json.custom/RiskCategory: ReferencesRiskCategoryfromcustomDefinitions.cdm.json.
Handling Conflicts
In scenarios where multiple imported documents contain entities with identical names, monikers help disambiguate references, ensuring that GRIx accurately identifies and utilizes the correct entity definitions.
Conflict Resolution Example:
In this example, personFullName is defined in customDefinitions.cdm.json and is referenced using the custom moniker to avoid conflicts with any similarly named entities in other imported documents.
Best Practices
Consistent Moniker Usage: Assign meaningful monikers to imported documents to facilitate easy referencing.
Qualified References: Always use monikers when referencing entities from imported documents to maintain clarity.
Import Order Management: When monikers are not used, ensure a consistent import order to manage precedence in case of naming conflicts.
