The term "Data Node" is ubiquitous in our domain language, however it is not well defined in our Domain Model. This should be reviewed as it seems this is a primary domain concept that is not expressed in our model. This situation could be considered the "Anemic Domain" anti-pattern.

Domain Language and concepts that seem to be missing:

1) Data Node "root identifier" or name-space "prefix".
2) Data Node seems to have "policies" regarding data organization, discovery and process.
3) May contain configuration details such as keystore certificates, points of contact, etc.
