      VNF Requirements and Guidelines impacting the VNF package are described below.
      A table collecting the VNF Package Requirements coordinated with the VNF SDK, SDC, Validation and Modeling project.

      Step 1 identify from the list of Amsterdam requirements, those that are testable by VNF Package inspection https://wiki.onap.org/display/DW/VNF+Requirements+Testability

      Step 2 from that list identify the requirements where information elements have been identified https://wiki.onap.org/pages/viewpage.action?pageId=16004636 ONAP R2+ Resource IM Clean version

      step 3 from that list identify the requirements where the information elements have some range limits or naming conventions identified. - SOL001, SOL004

      The following VNF package requirements guide:

      • VNF SDK project developing a tool allowing a VNF provider to create a VNF package compliant with ONAP VNF package model - see attached ppt.
      • SDC project developing an entity for VNF package parsing, validation and on-boarding.

      The VNF package requirements are arranged and numbered as in [https://wiki.onap.org/display/DW/VNF+Requirements+Testability] and mapped to the R2 Info Model and CASR where applicable.
