• Experimenting with IFPRI OAI (we want to harvest their publications)
• After reading the ContentDM documentation I found IFPRI's OAI endpoint: http://ebrary.ifpri.org/oai/oai.php
• After reading the OAI documentation and testing with an OAI validator I found out how to get their publications
• This is their publications set: http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&from=2016-01-01&set=p15738coll2&metadataPrefix=oai_dc
• You can see the others by using the OAI ListSets verb: http://ebrary.ifpri.org/oai/oai.php?verb=ListSets
• Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in dc.identifier.fund to cg.identifier.cpwfproject and then the rest to dc.description.sponsorship

dspacetest=# update metadatavalue set metadata_field_id=130 where metadata_field_id=75 and (text_value like 'PN%' or text_value like 'PHASE%' or text_value = 'CBA' or text_value = 'IA');
UPDATE 497
dspacetest=# update metadatavalue set metadata_field_id=29 where metadata_field_id=75;
UPDATE 14

• Fix a few minor miscellaneous issues in dspace.cfg (#227)

2016-06-02

• Testing the configuration and theme changes for the upcoming metadata migration and I found some issues with cg.coverage.admin-unit
• Seems that the Browse configuration in dspace.cfg can't handle the '-' in the field name:

webui.browse.index.12 = subregion:metadata:cg.coverage.admin-unit:text

• But actually, I think since DSpace 4 or 5 (we are 5.1) the Browse indexes come from Discovery (defined in discovery.xml) so this is really just a parsing error
• I've sent a message to the DSpace mailing list to ask about the Browse index definition
• A user was having problems with submission and from the stacktrace it looks like a Sherpa/Romeo issue
• I found a thread on the mailing list talking about it and there is bug report and a patch: https://jira.duraspace.org/browse/DS-2740
• The patch applies successfully on DSpace 5.1 so I will try it later

2016-06-03

• Investigating the CCAFS authority issue, I exported the metadata for the Videos collection
• The top two authors are:

CGIAR Research Program on Climate Change, Agriculture and Food Security::acd00765-02f1-4b5b-92fa-bfa3877229ce::500
CGIAR Research Program on Climate Change, Agriculture and Food Security::acd00765-02f1-4b5b-92fa-bfa3877229ce::600

• So the only difference is the "confidence"
• Ok, well THAT is interesting:

dspacetest=# select text_value, authority, confidence from metadatavalue where metadata_field_id=3 and text_value like '%Orth, %';
 text_value |              authority               | confidence
------------+--------------------------------------+------------
 Orth, A.   | ab606e3a-2b04-4c7d-9423-14beccf54257 |         -1
 Orth, A.   | ab606e3a-2b04-4c7d-9423-14beccf54257 |         -1
 Orth, A.   | ab606e3a-2b04-4c7d-9423-14beccf54257 |         -1
 Orth, Alan |                                      |         -1
 Orth, Alan |                                      |         -1
 Orth, Alan |                                      |         -1
 Orth, Alan |                                      |         -1
 Orth, A.   | 05c2c622-d252-4efb-b9ed-95a07d3adf11 |         -1
 Orth, A.   | 05c2c622-d252-4efb-b9ed-95a07d3adf11 |         -1
 Orth, A.   | ab606e3a-2b04-4c7d-9423-14beccf54257 |         -1
 Orth, A.   | ab606e3a-2b04-4c7d-9423-14beccf54257 |         -1
 Orth, Alan | ad281dbf-ef81-4007-96c3-a7f5d2eaa6d9 |        600
 Orth, Alan | ad281dbf-ef81-4007-96c3-a7f5d2eaa6d9 |        600
(13 rows)

• And now an actually relevent example:

dspacetest=# select count(*) from metadatavalue where metadata_field_id=3 and text_value like 'CGIAR Research Program on Climate Change, Agriculture and Food Security' and confidence = 500;
 count
-------
   707
(1 row)

dspacetest=# select count(*) from metadatavalue where metadata_field_id=3 and text_value like 'CGIAR Research Program on Climate Change, Agriculture and Food Security' and confidence != 500;
 count
-------
   253
(1 row)

• Trying something experimental:

dspacetest=# update metadatavalue set confidence=500 where metadata_field_id=3 and text_value like 'CGIAR Research Program on Climate Change, Agriculture and Food Security';
UPDATE 960

• And then re-indexing authority and Discovery...?
• After Discovery reindex the CCAFS authors are all together in the Authors sidebar facet
• The docs for the ORCiD and Authority stuff for DSpace 5 mention changing the browse indexes to use the Authority as well:

webui.browse.index.2 = author:metadataAuthority:dc.contributor.author:authority

• That would only be for the "Browse by" function... so we'll have to see what effect that has later
