Project Overview

  • Both Python and Java based Parser will not be updated in R10, the R10 release will use the same as previous release. 

  • The etsicatalog project provides package management service and parser service by Micro Service. It can be used to store packages distributed by the SDC, which then can be consumed by other projects or components, such as UUI, VF-C, SO etc. It also includes a TOSCA parser service.
