+Alternative Title is made repeatable. 
+- One will need to update database with updated citation block.
+`curl http://localhost:8080/api/admin/datasetfield/load -H "Content-type: text/tab-separated-values" -X POST --upload-file scripts/api/data/metadatablocks/citation.tsv`
+- One will also need to update solr schema:
+Change in "alternativeTitle" field  multiValued="true" in `/usr/local/solr/solr-8.11.1/server/solr/collection1/conf/schema.xml` 
+Reload solr schema: `curl "http://localhost:8983/solr/admin/cores?action=RELOAD&core=collection1"`
+
+Since Alternative Title is repeatable now, old json apis would not be compatable with a new version since value of alternative title has changed from simple string to an array.
+For example, instead "value": "Alternative Title", the value canbe "value": ["Alternative Title1", "Alternative Title2"]
