Cloud Information Model

Structure

Main directories:

• dist: distribution of the full model as a single file in each of the supported formats
• src: model metadata structured by subject area, entity group and property group
• html: model documentation (HTML)

A common JSON-LD context that is used by every single JSON-LD file can be found at src/context.jsonld. This is the context referred from http://cloudinformationmodel.org/context.jsonld.

The model metadata is structured in subject areas under src/subjectAreas/{subjectArea}. A about.jsonld file contains a small description of the subject area itself.

Each subject area is divided into entity groups stored in nested directories: src/subjectAreas/{subjectArea}/{entityGroup}.

Each entity group has the following JSON-LD main files:

• concepts.jsonld: conceptual ontology describing the business model for that entity group
• schema.jsonld: canonical schema for data following the semantics of the business model

Additionally, reusable conceptual properties are stored in the src/propertyGroups/{propertyGroup} directories. Each property group has a single JSON-LD file:

• concepts.jsonld: conceptual ontology describing the business model properties in the property group.

A relational mapping for the canonical schema is provided in the following files in each entity group:

• database.sql: SQL DDL statements for the canonical schema
• database.r2rml: Relational to RDF mapping for the schema that can be generated from the SQL DDL statements

Additionally, each entity group has the following mappings:

• concepts.yaml: YAML file describing the business model ontology for that entity group using AML
• schema.yaml: YAML file describing the canonical schema for the information in that business model using AML
• schema.json: JSON schema generated from the canonical schema
• schema.raml: RAML datatypes generated from teh canonical schema

Global files

• The full model can be downloaded as a single JSON-LD file at dist/model.jsonld.
• Two stand-alone AML files with the conceptual model and canonical schema can be found at dist/concepts.yaml and dist/schema.yaml.
• Global SQL DDL statements file for the full model and R2RML mappings can be found at dist/schema.sql and dist/schema.r2rml.
• Global RAML types and JSON Schema files can be found at: dist/schema.raml and dist/schema.json.
