CIMDifference

[derrickoswald]

The ability to read CIM files into two different named RDD sets, i.e. RDD[\<CIM class>], via Allow for named RDD variations, allows for generation of a difference file based on two reference CIM files.

This issue tracks the creation of a new standalone executable called CIMDifference, that will perform this task.

Essentially:

• read file 1 with ch.ninecode.cim.name_template="%s_1"
• read file 2 with ch.ninecode.cim.name_template="%s_2"
• foreach RDD[\<CIM class in set 2>]
  • leftOuterJoin with RDD[\<CIM class in set 1>] and process additions and modifications
• foreach RDD[\<CIM class in set 1>]
  • leftOuterJoin with RDD[\<CIM class in set 2>] and process deletions

Commit efdf3aba596b1ca90947a2d14669ca3dd291b4d9 adds CIMDifference artifacts to the Maven repo. Actual implementation uses fullOuterJoin() instead of the separate foreach loops mentioned above.
