What should be in a Schema?
Element names, labels, descriptions Element values: types / patterns / value sets Structures: flat / tree / graph, cardinality, etc Complex constraints Relationships with other schemas:
inheritance, subtyping, composition, etc Semantics: relationships with ontologies. Schema versioning ...
Scope for Schema-driven Apps
Metadata entry and display Validation of metadata Mapping between metadata representations:
XML vs RDF vs <meta> vs ... need representation independent schemas
Metadata conversion / schema versions Extracting / harvesting metadata from other
sources
Recent eResearch Group Tools
ARCHER metadata tools: MDE: a schema driven (XML) metadata editor MSF: tools for defining metadata schemas MDSR: simple metadata schema repository
Pronto ontology repository DIAS-B tools:
Danno annotation repository (annotea + ...) Dannotate annotation tool
LORE annotation tool. SourceForge project: “metadata-net”
Future Work
Schema-driven annotation tools Annotation of objects (vs web pages) Annotation of images, maps, etc Integrate MDE/MSF and Danno/Dannotate Support for more schema types in Pronto Stand-alone editing, repository components
Completing the Annotea specification Annotation schema work
