OASIS members and other interested parties,
The OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC [1] members have recently approved a Committee Specification Draft (CSD) and submitted it for 30-day public review:
TOSCA Simple Profile in YAML Version 1.0
Committee Specification Draft 04 / Public Review Draft 01
27 August 2015
Overview:
The TOSCA Simple Profile in YAML specifies a rendering of TOSCA which aims to provide a more accessible syntax as well as a more concise and incremental expressiveness of the TOSCA DSL in order to minimize the learning curve and speed the adoption of the use of TOSCA to portably describe cloud applications.
This proposal describes a YAML rendering for TOSCA. YAML is a human friendly data serialization standard (
http://yaml.org/) with a syntax much easier to read and edit than XML. As there are a number of DSLs encoded in YAML, a YAML encoding of the TOSCA DSL makes TOSCA more accessible by these communities.
The TOSCA metamodel uses the concept of service templates to describe cloud workloads as a topology template, which is a graph of node templates modeling the components a workload is made up of and as relationship templates modeling the relations between those components. TOSCA further provides a type system of node types to describe the possible building blocks for constructing a service template, as well as relationship type to describe possible kinds of relations.
Public Review Period:
The public review starts 21 September 2015 at 00:00 UTC and ends 20 October 2015 at 23:59 UTC.
