“Using Schema and Value Vocabularies to Provide Consistency Across Structured Content” Panel
Description: Schema vocabularies specify the properties and attributes related to the vocabulary’s application, while value vocabularies specify the valid instances for those properties and attributes. Schema vocabularies can point to existing schemas such as SKOS (Simple Knowledge organization Scheme), RDFS (RDF Schema), Dublin Core, FOAF (Friend of a Friend), Schema.org, etc.
Value vocabularies can be simple controlled vocabularies, or taxonomies, ontologies, or other types of terminologies. Value vocabularies are crucial for consistency, discoverability, and reusability. Whether tagging, filtering, or defining relationships between concepts, value vocabularies bring clarity and reduce ambiguity.
This panel will discuss the interplay between schema vocabularies that structure content with value vocabularies that provide consistency across structured content, and particularly how automation can optimize the linked data ecosystem.
Panelists are: Lief Erickson, Heather Hedden, Noz Urbina, and Peter Winstanley, with Joseph Busch moderating.

“Taxonomies in Support of Search”
Description: Taxonomies and search have often been considered as different, competing tools for information findability. When people think of taxonomies, they might consider only displayed hierarchies or facets, and users might prefer to simply use a search box. Taxonomies, and more broadly controlled vocabularies, can support search in multiple ways, using synonyms/variants, search refinements, hierarchies, search-suggest terms in a drop-down, and a search thesaurus. The presentation will address and show examples of each of these ways that taxonomies can support search, and it will go into detail on the options for search refinements (facets). Finally, the role of AI with taxonomies and search will be discussed.

Book Sale and Signing Events

Heather Hedden signs copies of The Accidental Taxonomist, offered for sale at a conference discount at many of the conferences at which she speaks. Some conferences, such as KMWorld, have a book sale table. At other conferences listed above, Heather Hedden will have a few books along to sell and sign when meeting informally at the conference.
Heather Hedden will have on hand a few copies for sale at the DCMI conference in Barcelona in October and a full book sale and signing event at KMWorld in Washington, DC in November.
