DDE Building Blocks

Modular metadata schema components for Deep-time Digital Earth (DDE), built using the OGC Building Blocks pattern.

Structure

DDEproperties (7 schema components)

Property building blocks that define DDE-specific metadata elements: geographic dataset, imagery, optional/required fields, resource types, service info, and subject classification.

DDEProfiles (11 resource type profiles)

Metadata profiles that compose property building blocks with CDIF base schemas:

• DDEDiscovery — base DDE discovery profile (composes cdifMandatory + cdifOptional + DDE properties)
• 10 resource type profiles — DDEAudioVisualProduct, DDECollection, DDEDataset, DDEDocument, DDEEvent, DDEFunctionalResource, DDEImage, DDESemanticResource, DDEService, DDESoftware

Cross-repo imports

This repository imports shared schema.org and CDIF property building blocks from metadataBuildingBlocks via the OGC Building Blocks import mechanism.
