Xades4j with custom commitments types

I will need to set customs commitments types (with xades4j, of course).

I had a look to the lib and I got the feeling that is not possible to do so.
The commitments type are finals. 

.withCommitmentType( AllDataObjsCommitmentTypeProperty commitment )
And AllDataObjsCommitmentTypeProperty  is a final class.
The same for the individual commitments.

Is my interpretation correct?

Does it make sense to extend this possibility in xades4j?

Solution

  • You're looking for a way to specify CommitmentTypeQualifiers as defined in section 7.2.6 of XAdES? Or just need to change the commitment type identifier? In case it's the latter and the identifier is an URI, both AllDataObjsCommitmentTypeProperty and CommitmentTypeProperty have a constructor you can use. IF not, you're correct.

    Supporting arbitrary "untyped" parameters on the commitment indication properties is not easy on the current architecture. I have to see if it would be feasible using some of the existing extensibility points or using another approach. Do you have any suggestions?
