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. |
