+Resource Definition
+-------------------
+.. toctree::
+   :maxdepth: 2
+
+Introduction:
+=============
+A Resource definition models the how a specific resource can be resolved.
+
+A resource is a variable/parameter in the context of the service. It can be anything, but it should not be confused with SDC or Openstack resources.
+
+A Resource definition can have multiple sources to handle resolution in different ways. The main goal of Resource definition is to define re-usable entity that could be shared.
+
+Creation of Resource definition is a standalone activity, separated from the blueprint design.
+
+As part of modelling a Resource definition entry, the following generic information should be provided:
+

+
+
+Below are properties that all the resource source have will have
+
+The modeling does allow for data translation between external capability and CDS for both input and output key mapping.

+
+
+Example:
+========
+
+vf-module-model-customization-uuid and vf-module-label are two data dictionaries. A SQL table, VF_MODULE_MODEL, exist to correlate them.
+
+Here is how input-key-mapping, output-key-mapping and key-dependencies can be used:

+Resource source:
+================
+
+Defines the contract to resolve a resource.
+
+A resource source is modeled, following TOSCA_ node type definition and derives from the Resource_ source.
