However in order to make these templates adaptable and feasible for purpose like deployment orchestration/automation, certain tooling mechanism that provides template translation is necessary. Project Parser will help to provide such tooling mechanism, by parsing Telecom operators’ descriptors/records into TOSCA/CAMP templates and then further translate TOSCA/CAMP templates into certain common templates, which could be used in IaaS orchestration projects like OpenStack Heat. For Release B, Parser offers the following capabilities: * Integration of Heat-Translator Liberty release code. (both heat in-tree code and standalone package are provided) * Yang2Tosca module which offers the capability to translate yang based scriptors to tosca formate templates. Users could further use Heat-translator module to translate this tosca template to Heat Orchestration template. Yang2Tosca module could be installed seperately after user installed OPNFV B release platform. * The "parser_new_keywords" document demonstrate a set of keywords concluded by Parser team that need to be supported in tosca to heat translation. However it should be noted that these keywords only serve as a roadmap. We will start from Release C to indicate which specific set of keywords are supported in Parser. * The "vRNC_tosca_intro" document describes Parser's use case analysis on vRNC scenario. The "example" folder contains examples of tosca-nfv standard and vRNC scenario. See also https://wiki.opnfv.org/parser . For Release C, Parser offers additional capabilities: * Policy2Tosca module which enables policy related fields in tosca could be translated into heat orchestration template correctly. Policy2Tosca module could be installed seperately after user installed OPNFV C release platform. * Tosca2Heat enhancements which includes a set of feature addons for OpenStack tosca-parser module which is integrated in the OPNFV C release platform. * Additional testing support. ..
