Linking the American Art Museum to the Cloud What is Linked Open Data? (Bear with me…) Data published by exis0ng internet protocols that use a URI (Unique Resource Indicator) as the primary discoverable en0ty for a resource (e.g. person, object, web page, etc.) THE FIVE STARS OF LOD (Tim Berners Lee): ★ make your stuff available on the web (whatever format) under an open license ★★ make it available as structured data (e.g., Excel instead of image scan of a table) ★★★ use non-‐proprietary formats (e.g., CSV instead of Excel) ★★★★ use URIs to iden0fy things, so that people can point at your stuff ★★★★★ link your data to other data to provide context
Linking the American Art Museum to the Cloud What is Linked Open Data good for? For the American Art Museum, Linked Open Data will: • Make our collec0ons data more discoverable on the web • Allow for more sophis0cated queries about our collec0ons • Create connec0ons with other museums • Create connec0ons with other non-‐museum resources • Create connec0ons with our dispersed content on social media • Help us beMer adapt to the changing web
Linking the American Art Museum to the Cloud GeLng Started Our IniMal QuesMons • Will it take a lot of 0me and resources to prepare our data? • How does LOD differ from what a Google search can do? • Is it foolish to be doing this before standards are in place? • What if people do inappropriate things with our data? • Will it be worth the 0me and effort in the end? • How do we handle all of the non-‐public data that we have? The Project • Working with the Informa0on Sciences Ins0tute (ISI) and Department of Computer Science at
the University of Southern California. • Goal: Publish 5-‐star Linked Open Data of our complete collec0ons data. • Project Phases: Prepare the data, Create an ontology, map the data to RDF, link the data to
hub datasets, publish the data.
Linking the American Art Museum to the Cloud The Process Preparing the data • Collec0ons data is stored in TMS • Publish only the data that is already visible on our website • Use an exis0ng output report from TMS • Several fields needed to be interpreted first Designing the Ontology • We built our ontology around exis0ng ontologies
• Europeana Data Model v.2 • SKOS • Dublin Core • RDA Group 2 Elements • schema.org
Linking the American Art Museum to the Cloud The Process Mapping the Data to RDF (Resource DescripMon Framework) • Used KARMA tool to model the data (hMp://www.isi.edu/integra0on/karma/)
Linking the American Art Museum to the Cloud The Process Linking the Data to External Data • Verify matches before publishing
Linking the American Art Museum to the Cloud The Process Linking the Data to External Data (cont…) • Have already linked ar0sts to:
• DBPedia -‐ 2,194 • New York Times -‐ 70
• Addi0onally, can link ar0sts to: • GeMy Union List of Ar0st Names -‐ 2,110 (ULAN is not yet published as LOD, but will be) • Rijksmuseum dataset – 551 (links are not yet verified)
• In the works: • Linking places • Linking concepts • Linking to datasets from other museums • Linking to social media content
Publishing • Plan to publish complete dataset under a CC0 license
Linking the American Art Museum to the Cloud Conclusions • Able to convert data for en0re collec0on • Using KARMA to model the data and verify links reduced 0me and resources • LOD eliminates the “noise” of a Google search What’s next? • Embed LOD on our website • Improve representa0on of ar0sts on Wikipedia • Create an ongoing maintenance plan • Tag object-‐ and person-‐related museum content on social sites • Inves0gate mapping and linking an artwork’s subject • Expand the LOD in ways that will enhance research • Create a tool that allows users to “curate stories”:
