Metacat

For MNs that haven't set the archived flag to false on create(), set it here. Also, ensure that the CN sync code sets the authoritative and origin member node fields.

On MN.create(), set the archived flag to be false. This field isn't required in the schema, but is needed by the DataONE indexer once objects are sync'd.

refactor generate system meta loop to the factory class -- to be reused in sysmeta and ORE generation

When managing obsoletes/obsoletedBy system metadata fields, set the archived flag to false initially, and set it to true on system metadata for objects that a revision obsoletes.

check that the resourceMap (based on Id only) does not currently exist in the local metacat when generating OREs

In IdentifierManager.updateSystemMetadata(), add a check for invalid system metadata (fields that throw a NullPointerException on access) to ensure that system metadata is populated correctly. Updated calling classes to handle the exception.

Handle SQLExceptions when trying to save system metadata locally.

Convert SQLExceptions to RuntimeExceptions for Hazelcast MapStore operations.

Keep the hzIdentifiers set in sync with the Metacat systemmetadata table. If entries are added/updated in the hzSystemMetadata map, make sure the identifier is in the set. If (for some administrative reason) the entry is removed, remove the identifier from the set. This usually doesn't happen.

When loading all keys from Metacat into the hzSystemMetadata map, also load identifiers into the hzIdentifiers set if they are not already there. Although entries may be evicted from the map, the list of identifiers will remain. The list will have a fairly small memory footprint since it's just identifiers.
