This function inserts, replaces or removes structured history data or annotations into the history database at the specified timestamps for one or more HistoricalDataNodes.
Structured history data provides metadata describing an entry in the history database. The server shall define what uniqueness means for each structured history data structure type. For example, a server may only allow one annotation per timestamp, which means the timestamp is the unique key for the structure. Another server may allow for multiple annotations to exist per user, so a combination of a username, timestamp, and message may be used as the unique key for the structure. In the following sections the terms “Structured Histroy Data exists” and “at the specificed parameters” means a matching entry has been found at the specified timestamp using the Server’s criteria for uniqueness.
In the case where the Client wishes to replace a parameter that is part of the uniqueness criteria, the resulting StatusCode would be Bad_NoEntryExists. The Client must remove the existing structure and then insert the new structure.
Insert functionality
Setting performInsertReplace = INSERT_1 inserts structured history data, such as annotations, into the history database at the specified parameters for one or more properties of HistoricalDataNodes.
If a structured history data entry already exists at the specified parameters, the StatusCode shall indicate Bad_EntryExists.
Replace functionality
Setting performInsertReplace = REPLACE_2 replaces structured history data such as annotations in the history database at the specified parameters for one or more properties of HistoricalDataNodes.
If a structured history data entry does not already exist at the specified parameters, the StatusCode shall indicate Bad_NoEntryExists.
Update functionality
Setting performInsertReplace = UPDATE_3 inserts or replaces structured history data such as annotations in the history database at the specified parameters for one or more properties of HistoricalDataNodes.
If a structure history data entry already exists at the specified paramters, it is deleted and the value provided by the Client is inserted. If no existing entry exists, the new entry is inserted.
If an existing entry was replaced successfully, the StatusCode shall be Good_EntryReplaced. If a new entry was created, the StatusCode shall be Good_EntryInserted. If the server cannot determine whether it replaced or inserted an entry, the StatusCode shall be Good.
Remove functionality
Setting performInsertReplace = REMOVE_4 removes structured history data such as annotations from the history database at the specified parameters for one or more properties of HistoricalDataNodes.
If a structure history data entry exists at the specified parameters, it is deleted. If structured history data does not already exist at the specified parameters, the StatusCode shall indicate Bad_NoEntryExists.
