Authority data: the good, the dirty and the semantic

Description:

A presentation at Samvera Connect 2019, originally titled"Questioning Authority, Questioning authority is a Samvera developed gem that provides a standard way of accessing external authority controlled vocabularies. As part of the Mellon Foundation-funded Linked Data for Production (LD4P) project, this gem was expanded to include a module for general processing of authorities that provide linked data regardless of ontology. This module leverages the existing normalized data format of QA and expands it to include extended context allowing for more accurate selections. Also part of this work was the development of QaServer which is an engine from which you can build a standalone Rails app acting as a service point for submitting queries to QA. The QaServer includes a management UI to explore the availability of authorities and the performance of requests. We will look at recent enhancements to QA, the QaServer UI, a caching system for linked data authorities without an API, metadata entry using extended context, and how we’ve leveraged linked data in some of our user facing applications., and Connecting to Authorities through Linked Data", described thus

Efficient and Reliable Access to Authorities with Contextual Lookup

Description:

Want to move beyond a simple autocomplete field for controlled vocabularies? Want a more accurate selection process? We will look at a Hyrax demo app that uses questioning authority to search linked data authorities and extracts multiple predicate values from search results to provide additional context in a lookup table to help with the selection process from a controlled vocabulary. The presentation will include direct access to OCLC Fast, locally cached access to Library of Congress and GeoNames, as well as others. and A presentation given at Connect 2017 originally advertised as "Lookup with Context to select metadata values from a controlled vocabulary" and described thus
