Good day

I'm testing the Orcid support in DSpace 6.3 going by instructions here.

https://wiki.lyrasis.org/display/DSDOC6x/ORCID+Integration

I haven't tried to use Authority Control for DSpace before.

Another resource I have found useful is a webinar done by Atmire a year ago:

https://www.atmire.com/articles/detail/webinar-recording-orcid-for-dspace-repositories

I am not sure I understand the functionality of the confidence levels.

The initial condition in the database is as follows:

select count(*), confidence from metadatavalue where metadata_field_id = 3 
group by confidence;

 count | confidence
   -------+------------
    19    |          0
   206   |        300
 40067 |         -1
     1     |        500
    13    |        600

This is more or less expected, with the confidence levels of 
dc.contributor.author values at -1 or "Unset".

If I then select a random record and select an author with and Orcid from a 
lookup, say McCaslin, Laura, 0000-0002-6705-8755.

I can then see that the earlier entry has been deleted and a new one now exists 
but in an incomplete state:

select * from metadatavalue where text_value = 'McCaslin, Laura';
 metadata_value_id | metadata_field_id |   text_value    | text_lang | place |  
                 authority                   | confidence |           
dspace_object_id
-------------------+-------------------+-----------------+-----------+-------+-----------------------------------------------+------------+--------------------------------------
           5703635 |                 3 | McCaslin, Laura | en        |     0 | 
will be generated::orcid::0000-0002-6705-8755 |          0 | 
4a21c3be-48c2-4255-95e2-20950df6b670


I don't understand why the confidence level is only at 0 which signifiies that 
"No reasonable confidence value is available". I just selected that value 
manually using the lookup mechanism. Should it not be 600? (see here for the 
table of confidence values: 
https://wiki.lyrasis.org/display/DSPACE/Authority+Control+of+Metadata+Values#AuthorityControlofMetadataValues-Confidence)


Instead, unless I'm mistaken, a placeholder value ("will be generated::....") 
is inserted that seems to get replaced only when ./dspace index-authority is 
run. From a technical perspective it does not make sense to me as the data for 
Laura McCaslin has just been retrieved from the Orcid API and unless the 
index-authority job is run frequently there will only be a useless placeholder 
value behind it until it is run.

After index-authority is run the authority value is replaced with an uuid:

select * from metadatavalue where text_value = 'McCaslin, Laura';
 metadata_value_id | metadata_field_id |   text_value    | text_lang | place |  
            authority               | confidence |           dspace_object_id
-------------------+-------------------+-----------------+-----------+-------+--------------------------------------+------------+--------------------------------------
           5703635 |                 3 | McCaslin, Laura | en        |     0 | 
10ad8f3f-3331-4a23-b032-00f1cec31b6a |          0 | 
4a21c3be-48c2-4255-95e2-20950df6b670


but the confidence is still unchanged.

My main question is, how is a confidence value of 600 or "Accepted" achieved? 
The 13 values already in my repo with 600 were all manually entered BEFORE 
authority control was enabled. I don't understand why they have 600.


Thanks for your help
