> Governance classifications may be ordered and contain sub-classifications.
> For example a classification "confidentiality" may contain an *ordered* set of values such as
>  - unclassified
>  - internal use
>  - confidential
>  - sensitive
>  - restricted
>  - top secret
> The ordering is a logical progression -- going from the least confidential to the most confidential. 
> When these governance classifications are retrieved or checked against we may wish to performance range checks. For example in a ranger policy we may wish to do the equivilent of "if confidentiality >= confidential then.."
> Furthermore these classifications may be hierarchical. The mail thread below uses the example "confidential/business confidential" and "confidential/personal confidential". these are at an equivilent level, but different
> Atlas should be extended to support this.(further JIRAs would be needed to update ranger)
> In terms of implementation, For existing apis/tag integration we may consider a form of flattening or overloading the name to ease migration.
> Note that this will prereq the anticipated work on ATLAS-1187 to introduce classifications, but I've split this further development out so that we can get a first pass done in 1187
> This suggestion first came up in the mailing list discussion on "Rename Trait to classification", which relates to ATLAS-1187 - also viewable on gmane at news://news.gmane.org:119/nt0jdp$ml0$1@blaine.gmane.org
