PODD
PODD is the Phenomics Ontology Driven Data repository. It is a semantic web enabled research data and metadata repository. PODD is designed to utilise an OWL/RDFS derived ontology as its data management schema. In the PODD schema we define conceptual metadata objects and their relationships. The PODD software then handles the instantiation of these concepts as metadata objects in RDF. This approach gives PODD a unique extensibility as the domain knowledge is entirely captured in the ontology (as it should be) and the operational aspects of the system (e.g. screen rendering, service inputs/outputs, etc) are derived purely from the content of the ontology. This means PODD is not just a repository for Phenomics, but is adaptable for any research data management requirements.
A key feature of PODD is the ability to manage high volume and high resolution heterogeneous datasets in a Project structure. This in turn supports collaboration around the data, data discovery, analysis and data publishing.

PODD Instances
Currently PODD is deployed on behalf of the Australian Plant Phenomics Facility (APPF) and the Australian Phenomics Network (APN)
The following implementations of PODD are available to limited public access:
APPF Test Instance
APPF Production Instance
