The document discusses three case studies related to making organizational taxonomies and resources more interoperable: 1) Integrating metadata across three Victorian government departments by aggregating, rationalizing, and harmonizing their schemas. 2) Repatriating cultural resources from the Quinkan people by using Dublin Core metadata with local extensions to provide a single access point for internal and external users. 3) The AccessForAll project, which uses metadata to match educational resources to individual learner needs and preferences to ensure equal accessibility. Standards are discussed as a way to balance local specificity and global interoperability.
