TOSCA Simple Profile in YAML Version 1.1 6.1 Overall Structure of a CSAR A CSAR zip file is required to contain one of the following: • a TOSCA-Metadata directory, which in turn contains the TOSCA.meta metadata file that provides entry information for a TOSCA orchestrator processing the CSAR file. • a yaml (.yml or .yaml) file at the root of the archive. The yaml file being a valid tosca definition template that MUST define a metadata section where template_name and template_version are required. The CSAR file may contain other directories with arbitrary names and contents. Note that in contrast to the TOSCA 1.0 specification, it is not required to put TOSCA definitions files into a special “Definitions” directory, but definitions YAML files can be placed into any directory within the CSAR file. Option 1 Option 2 Per TOSCA YAML v1.1: Due to the simplified structure of the CSAR file and TOSCA.meta file compared to TOSCA 1.0, the CSAR-Version keyword listed in block_0 of the meta-file is required to denote version 1.1.

Discussion Recommendation R1: TOSCA version spec: TOSCA Simple Profile in YAML Version 1.1 TOSCA CSAR-Version: 1.1 With option 1 (a TOSCA-Metadata directory ): Manifest file: CSAR package support with and without manifest file Recommendation R2: (initial drafting, under discussion) TOSCA version spec: TOSCA Simple Profile in YAML Version 1.1? TOSCA CSAR-Version: 1.1? With option 1 and or option 2: ? CSAR package support ??
