...

input:
a contribution jar or file system directory

steps:
Contribution Read

...

1. Find all artifacts

...

1. in the contribution
2. Read each artifact and create a model (apart from composites which are done later)

• Aggregate all definitions.xml files
• Read composites
• Enhance composite with policy sets based on appliesTo information Parse composites into in memory assembly model

  Contribution Resolution

  • resolve the contribution models against the physical artifacts available in the contribution.

  output:
  a contribution model in memory containing composite assembly models in memory

  New Policy Processing Phase

  <<The composite enhancement steps from the previous phase live here?>>

  • • For each composite file read the xml content first...
      • For each policyset in the domain...
        • Extract the value of 'appliesTo' attribute with is an xpath expression
        • Evaluate this expression against the composite xml
          • For each node that results out of the above evaluation
            • if the node contains an attribute named 'applicablePolicySets'
              • concatenate to its value, the name of the PolicySet
            • else
              • create an attribute named 'applicablePolicySet' and set its value to the name of the PolicySet

  ...

  • Wherever applicable the

  ...

  • composite's elements will have the additional attribute name 'applicablePolicySets'.

  ...

  • Parse composites into in memory assembly model

  Contribution Resolution

  • resolve the contribution models against the physical artifacts available in the contribution.

  output:
  a contribution model in memory containing composite assembly models in memory model creation.
