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. + +Upgrades from Arno +------------------------ + +For Release B, Parser offers the following additional 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. + +Upgrades from Brumapatra +----------------------- + +For Release C, Parser offers the following 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 (such as substitution mapping) +for OpenStack tosca-parser module which is integrated in the OPNFV C release platform. And the +main details are listed below: + + ** support substitution mapping semantic in tosca-parser: + - support parse and validation about substitution mapping definition; + - support import nested template; + - support deployment a node which is substituted by a template; + - support deployment a template alone which has substitution mapping definition. + + ** afinity and anti-affinity support when deploy servers: + - tosca.policies.Placement.Colocate; + - tosca.policies.Placement.Antilocate; + + ** add validation about input parameters; + + ** add high availability and block volume in compute translation; + + ** add ip output in compute translation; + + ** add deployment a whole vRNC testcase with parser. + +* Additional testing support. + +Upgrades from Colorado +---------------------- + +For Release D, Parser offers the following additional capabilities: + |
