Instantiation Rules
POMBA audit reports are generated based on the rules that applied in the rules engine generating the violations. The following is an initial capture of rules
| Rule | Data Sources | Attributes | Description | Category | Severity | Story | Release |
|---|
| 1 | Attribute Comparison | A&AI, SDN-C, Network Discovery | All | This rule compares all attributes by the same name from different Context Builders and returns a violation if the fields do no match. This includes the case where the name is present by the value is null in one of the cases. It does not produce a violation if one of the Context Builders is missing an attribute. Note in Casablanca, this will be implemented in a non-generic way, and made more generic as a future work item | Attribute Mismatch | MAJOR?ERROR | | Jira Legacy |

| If vfModule is present, I expect vserver/VMs to be present within this structure. |

| Coming soon to release near you | Future |
| 8 | dataQuality | * |
| When there is a problem with the data provided to the validation engine (data missing due to system issues, etc), this rule shall raise violations. Longer term the plan is to report this in a separate dataQuality field. Attributes only |

Note that Attribute Comparison in particular needs to check against the following, but should check everything it can
...
The rules that POMBA runs are extensible and anyone can add new rules. Note this is in code currently, so has to but can be done as part outside of a the development cycle and manually applied if desired. Ideas from for rules probably fall into two categories
