This work will implement a simple registry in xml format for storing the resulting resource and change information.


  • This code must store information regarding resulting resources and changes made to a system.
  • The resulting xml repository must use a strict schema to accomplish this.
  • The resulting xml must be easy to update for future changes.

Design details

  • This code will use jaxb to generate classes from our schema as well as marshaling and unmarshaling the data.
  • This code will keep track of both what has been installed and where it has been installed.

Impacts of this enhancement

  • The SDD runtime will be aware and be able to keep track of updates made to a user's system in a simple and concise fashion.

Open Issues/Questions

Schema needs to be designed.

How do we determine unique names and id's to identify the products installed? (i.e. similar names)

How do we accommodate the case of a user deletion not through our runtime?
