ShareableMetadata
Consistency • Use controlled vocabularies. • Use open, linked vocabularies
where available.• Use new tools to clean up
messy and inconsistent data.
Coherence • Does your data follow a logical model?
• Ontology: a model of your interpretation of the world– Resource Description
Framework– CIDOC-CRM
• Data models: how information is represented– Dublin Core Abstract Model– Europeana Data Model (EDM)– Future Linked Data versions of
CDWA/VRACore?
Context • Do your models fit the environment you are sharing with?
• Collections/Institutions as important context.
• Collections aren’t silos, they are important nodes in a network. They provide important context to resources.
ContextualMass
Contextual mass places the emphasis on collecting materials that work together as a system of sources, with meaningful interrelationships between different types of materials and subjects, to support research inquiry....selection is based on criteria that produce dense, rich, and cohesive groupings of sources for research and analysis.

Communication • We need to translate human-readable content standards into machine-understandable representations.– Validation of rules– Consistency/coherence checks
• Will we open our vocabularies to the world?
• Don’t just publish data. Publish:– Your models– How local vocabularies extend
shared vocabularies.
Trusted Linked Data
• Libraries, archives, and museums have traditionally been trusted sources of information on the Web.
• In an “anybody can say anything about anything” world, how do we build a reputation as a source of trusted Linked Open Data
