1 A Few considerations

• If we can ignore mutability of key attributes the schema largely holds, an XPATH can be used as unique key for each data element (fragment) 
• We should stick to an XPATH with equality operators on key attributes only (e.g. no access by list index).
• 255 characters may not be enough for an XPATH.
• Conditions on multiple key attributes in the XPATH will have to be ordered to work as a single string.
• 'MO type' will require another definition since it is path dependent in Yang. Schema node identifier is as close as it gets.
• Given the work done in Neo4J to flatten attributes the use of a JSON format (possibly binary) in another DB technology makes sense – it will be easier to store and retrieve (no need to flatten the whole structure).
