2 Taxonomy Strategies LLC The business of organized information Focus of this session v Best practices for specifying and using controlled vocabularies in DC-compliant information management applications.  Tradeoffs and best practices around organization-dependent vs. sharable common controlled vocabularies.  Tagging content for internal vs. external audiences using the same metadata and controlled vocabularies.  When and how to map different taxonomies to each other.

3 Taxonomy Strategies LLC The business of organized information For us, taxonomy work includes: v Metadata specification defines the properties needed to describe content so that it can be found & used. v Vocabularies are collections of terms that are used to specify some of the metadata properties.  Some vocabularies are big and hierarchical, some are small and flat. v An application profile specifies what metadata & vocabularies are required, and then represents them formally.

4 Taxonomy Strategies LLC The business of organized information Best practices (1) v Intranet and public taxonomies should be based on a common metadata specification and shared value vocabularies. v Some metadata attributes are directly mapable to DC, some will be local (locally declared). v Use qualified Dublin Core attributes. v Some vocabularies are sharable industry standards, while others will be organization-dependent. v Some value vocabularies will be particularly relevant to intranet content.

13 Taxonomy Strategies LLC The business of organized information Mapping taxonomies v More complicated approach than multiple attributes with multiple value vocabularies. v Cases:  One-to-one.  One-to many.  Parallel, independent hierarchies. v If mapping is done, then business rules can be used to  Automatically add attribute values.  Improve search.  Create multiple views into the same content. v An ontology specifies typed associative relationships  Typically “Is a” relationships.
