Expand description

API for working with Daml-LF packages.

Compiled Daml packages are represented as Daml-LF (“Ledger Fragment”) archives. An archive is a protobuf serialized bytes array which is typically stored in a dalf file. Multiple dalf archives can be combined along with a manifest file into a Dar (“Daml Archive”) file.

Serialized Daml-LF archives may also be retrieved from an existing ledger via the GetPackage method of the GRPC package_service (see here). The daml-grpc create provides an implementation of this service in the daml_package_service module.

See here for full details of Daml-LF.
