Taxonomy
•Hierarchical relations
•Tree structure
•Controlled Vocabulary
•A common language to communicate, translate and tag
Why do we need metadata?
•Very complex information landscape
Why do we need metadata?
•We need pointers to the correct information
So how do we create these pointers?
•Content AnalysisInterviews with the customersExplore current and proposed information systemsLook for structures and terms that can be usedIdentify candidates for metadata
•Metadata and Taxonomy WorkshopsGather key resources at the customerThrough different workshop exercises help them identify key metadata and taxonomy categories
So how do we create these pointers?
•Create a controlled vocabularyCreate an inventory of terms and categoriesAdd synonyms , translations and taxonomy information
So how do we create these pointers?
•Map metadata terms to information objectsInformation objects are abstract building blocks of sites and information systems, they are described by their metadata
So how do we create these pointers?
• Implement information objects as page templates or content types
•Verify
• Iterate
