Solum/specify-lang-pack-design

Reference BP: https://blueprints.launchpad.net/solum/+spec/specify-lang-pack

Proposed Implementation 1:

1) Get available language packs:

GET /v1/language-packs

Return: [

  {language-pack:org.openstack.java.Java-1.6},
  {language-pack:org.openstack.python.python3.3}

]

2) Specify language pack to be used as part of the application plan:

POST /v1/assemblies

{

 camp_version: CAMP 1.1
 artifacts: {
    artifact_type: org.openstack.python.pyc
    content: { href: helloworld }
    requirements:
       requirement_type: org.openstack.interpreted_by
       fulfillment: id:py33
  }
  services: {
     id:py33
     characteristics:
        characteristic_type: org.openstack.python.python3.3   <--- Specify existing language pack 
   }

}

Proposed Implementation 2 for GET:

If we consider language packs as being a 'component', then the GET call would need to change to something like:

GET /v1/components/

Return: [

  { name: 'Python language pack'
    type:language-pack:org.openstack.python.python3.3     <--- Type identifies that this component is a language pack
    description: 'This is Python language pack',
    tags: ['Python 3.3 Language Pack']
   },
    { name: 'Java language pack'
    type:language-pack:org.openstack.java.Java-1.6
    description: 'This is Java language pack',
    tags: ['Java 1.6 Language Pack']
   }

]
