[Feature] Duplicate Handling

[fbaig]

There is no mechanism to avoid duplicate elements in the current system. To start with,

• There should be no duplicate titles for all elements
• Specifically for publications, duplicate checking should be done on DOIs
• Possibly need to merge existing duplicate for the next release

[fbaig]

For publications
CREATE CONSTRAINT publication_doi FOR (p:Publication) REQUIRE p.external_link IS UNIQUE
For all nodes

Finding duplicates

MATCH (d1:Dataset), (d2:Dataset)
WHERE d1.title = d2.title AND NOT d1 = d2
RETURN d1, d2
