Namespaces

Each Concerto file starts with the name of a single namespace, which contains the base definitions of asset, event, participant and transaction. All definitions within a single file belong to the same namespace.

namespace foo

Imports

In order for one namespace to reference types defined in another namespace, the types must be imported. Imports can be either qualified or can use wildcards.

import org.accordproject.address.PostalAddress

import org.accordproject.address.*

Import also can use the optional from declaration to import a model file that has been deployed to a URL.

import org.accordproject.address.PostalAddress from https://models.accordproject.org/address.cto

Imports using a from declaration can be downloaded into the model manager by calling modelManager.updateExternalModels.

The Model Manager will resolve all imports to ensure that the set of declarations that have been loaded are globally consistent.
