 # Container Application Specification
 
 ## Problem Statement
-Currently there is no standard mechanism to define a composite multi-container application or composite service composed of aggregate pre-defined building blocks spanning multiple hosts and clustered deployments. In addition, the associated metadata and artifact management requires separate processes outside the context of the application itself.

+## Glossary
+* __Container Image__: Platform-agnostic term referring to Docker, Rkt or other packaging and transport protocol.
+* __Layered Image__: The foundation image of a container plus other tools, applications and content added.
+* __Association__ of container images related to Nulecule application:
++ __Aggregation__ - Reference to one or more discrete container images integral to the operation and loosely coupled to the lifecycle of the Nulecule application - can be another Nulecule Application or container image reference
++ __Composition__ - Reference to one or more container images that are required and tightly coupled to the Nulecule application with some functioning only in the presence of one or more referenced container images - can be another Nulecule Application or container image reference
+* __Include__ - Refers to the ability to include common resources, parameters or definitions needed to deploy onto a orchestration provider. For example, an OpenShift provider may include the kubernetes provider artifacts and add OpenShift functionality on top of kubernetes capabilities.
+* __Provider__ - Plugin interface for specific deployment platform, an orchestration provider
+* __Dependency Management__: Refers to the ability to define order of deployment and managed dependencies including configurable parameters layered on top of stock container images, as well as the providers included in the application definition
+* __Directed Graph__: Declarative representation of dependencies in the context of a Nulecule application
+* __Parameters__ - Variables that can have default values and can be overridden by the answers file
