Direct Known Subclasses:

VersionedDOIIdentifierProvider
```
public class DOIIdentifierProvider
extends FilteredIdentifierProvider
```
Provide service for DOIs using DataCite.
This class handles reservation, registration and deletion of DOIs using the direct API from DataCite. Please pay attention that some members of DataCite offer special services and want their customers to use special APIs. If you are unsure ask your registration agency.

Any identifier a method of this class returns is a string in the following format: doi:10.123/456.

                              IdentifierNotApplicableException
```
    Load a DOI from the database or creates it if it does not exist. This method can be used to ensure that a DOI exists in the database and to load the appropriate TableRow. As protected method we don't check if the DOI is in a decent format, use DOI.formatIdentifier(String) if necessary.
    
    Parameters:
    
    context - The relevant DSpace Context.
    
    dso - The DSpaceObject the DOI should be loaded or created for.
    
    doiIdentifier - A DOI or null if a DOI should be generated. The generated DOI can be found in the appropriate column for the TableRow.
    
    Returns:
    
    The database row of the object.
    
    Throws:
    
    SQLException - In case of an error using the database.
    
    DOIIdentifierException - If doi is not part of our prefix or DOI is registered for another object already.
    
    IdentifierNotApplicableException - passed through.
  - loadOrCreateDOI
```
protected DOI loadOrCreateDOI(Context context,
                              DSpaceObject dso,
                              String doiIdentifier,

                              IdentifierNotApplicableException
```
    Load DOI from database, or create one if it doesn't yet exist. We need to distinguish several cases.LoadOrCreate can be called with a specified identifier to load or create. It can also be used to create a new unspecified identifier. In the latter case doiIdentifier is set null. If doiIdentifier is set, we know which doi we should try to load or create, but even in such a situation we might be able to find it in the database or might have to create it.
    
    Parameters:
    
    context - - DSpace context
    
    dso - - DSpaceObject to identify
    
    doiIdentifier - - DOI to load or create (null to mint a new one)
    
    skipFilter - - Whether or not to skip the filters for the checkMintable() check
    
    Returns:
    
    Throws:
    
    SQLException
    
    DOIIdentifierException
    
    IdentifierNotApplicableException - passed through.
