It is +developed to parse TOSCA Simple Profile in YAML. It reads the TOSCA templates +and creates an in-memory graph of TOSCA nodes and their relationship. + +Architecture +------------ + +The TOSCA Parser takes TOSCA YAML template or TOSCA Cloud Service Archive (CSAR) +file as an input, with optional input of dictionary of needed parameters with their +values, and produces in-memory objects of different TOSCA elements with their +relationship to each other. It also creates a graph of TOSCA node templates and their +relationship. + +The ToscaTemplate class located in the toscaparser/tosca_template.py is an entry +class of the parser and various functionality of parser can be used by initiating +this class. In order to see an example usage of TOSCA Parser from a separate tool, +refer to the OpenStack heat-translator class TranslateTemplate located in the +translator/osc/v1/translate.py module. The toscaparser/shell.py module of tosca-parser +also provides a good reference on how to invoke TOSCA Parser from Command Line Interface. + +The toscaparser/elements sub-directory contains various modules to handle +various TOSCA type elements like node type, relationship type etc. The +entity_type.py module is a parent of all type elements. The toscaparser +directory contains various python module to handle service template including +topology template, node templates, relationship templates etc. The +entity_template.py is a parent of all template elements. + + +How To Use +---------- +Please refer to `doc/source/usage.rst <https://github.com/openstack/tosca-parser/blob/master/doc/source/usage.rst>`_ + +Project Info +------------ + +* License: Apache License, Version 2.0 +* Source: http://git.openstack.org/cgit/openstack/tosca-parser/ + |
