EML Publication Model for OW1 Dataset Metadata
Ecological Metadata Language (EML) structure defining how Rutgers OW1 Bottom Trawl Survey dataset-level metadata should be published. This schema defines EML elements with mappings back to source OW1 DatasetMetadata fields. Uses SKOS mapping predicates in reverse (EML elements map to OW1 fields) to document both semantic relationships and publishing structure.
Schema file: models/datasets/rutgers/ow1-to-eml-mappings.yaml
Purpose
EML provides standardized dataset-level metadata for the Darwin Core Archive.
