Class ScholixFlat

java.lang.Object
eu.dnetlib.dhp.schema.sx.scholix.flat.ScholixFlat
public class ScholixFlat extends Object
Flat representation of a Scholix link stored in the ScholExplorer ElasticSearch index.

The standard Scholix data model is hierarchical: a Scholix object contains nested ScholixResource objects for the source and target, each carrying structured sub-objects (identifiers, publishers, collected-from information, etc.). Indexing nested objects in ElasticSearch introduces complexity when querying across parent/child boundaries, so this bean denormalises the full link into a single, flat document that is easy to index, filter and aggregate directly.

Each instance describes one directed relationship between two scholarly research objects (e.g. a dataset linked to a publication). Source and target descriptors are stored as parallel lists where positional correspondence is preserved: element i of sourcePid belongs to the PID scheme stored at element i of sourcePidType, and likewise for the target.

Typical usage:


 ScholixFlat link = new ScholixFlat();
 link.setIdentifier("abc123");
 link.setRelationType("isSupplementTo");
 link.setSourceId("50|doi_dedup_____::...");
 link.setSourceType("dataset");
 link.setTargetId("50|doi_dedup_____::...");
 link.setTargetType("publication");
