-Introduction of Parser Project
-==============================
-
-In NFV, various templates (such as descriptors, records and so on) are utilized
-to describe the deployment requirements (such as basic VM requirements – vCPU,
-memory, storage, as well as the NFV acceleration management requirement such as
-Huge Pages support, SR-IOV, NUMA affinity, DPDK support etc.),
-the post-instaniation records (such as storage usage report, CPU performance
-report etc.) or other purposes. 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 (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.
