Advancing metadata practice: Quality, Openness, Interoperability

Following up on DC-2016 in Copenhagen, with its look towards the changing role of metadata in the Second Machine Age, this year's conference will focus on technologies and practices that are advancing how we can create and manage good metadata. Interoperability and openness have been guiding principles of the DCMI community for over twenty years, and these principles have evolved through the development of Semantic Web standards and Linked Open Data. A deluge of new data sources is magnifying the perennial challenge of metadata quality but also inspiring the development of innovative tools, practices, and solutions, the focus of this year's conference.

In conjunction with each conference, the DCMI community holds an Annual Meeting at which DCMI citizens discuss ongoing work in areas such as vocabulary management, website design, and RDF validation. Together, the Conference and Annual Meeting provide opportunities for seasoned professionals, newcomers, students, apprentices, and early career professionals to share knowledge and experience. The meeting is a venue for practitioners in public- and private-sector initiatives to network and compare notes. Following the pattern of last year's conference in Copenhagen, DC-2017 will overlap with the annual meeting of ASIS&T, providing additional opportunities for professional interaction.

These gatherings advance DCMI's mission of promoting the interoperability and harmonization of metadata, from element schemas and Semantic Web vocabularies to application profiles, ontologies, and knowledge organization systems.

Special Sessions

Taming the Graph: Profiles over Linked Data

Title: Taming the Graph: Profiles over Linked Data
Day/Time: Friday, 8:30-5:30
Venue: TBA

Abstract: The idea of application profile was proposed at a Dublin Core workshop in 2000 as a way to customize metadata for specific application domains, mixing-and-matching multiple metadata vocabularies as needed, and to share these customizations within communities of practice. This day-long event will start with a look back at how the discourse around profiles has evolved since 2000, then it will examine new technologies that can help us tame the boundless sea of Linked Data with controlled metadata. This event is sponsored by the DCMI, which participates in W3C efforts to develop standards relevant to profiles and seeks direction for its future work, and by LD4, a coordinated program to advance the use and utility of linked data in research and cultural heritage organizations, especially libraries.

Linked Data for Production

Title: Linked Data for Production (LD4P): Technical services workflow evolution through Tracer Bullets
Day/Time: Thursday, 1:30-3:00
Venue: TBA

Abstract: Linked Data for Production (LD4P) is a Mellon-supported collaboration between six institutions (Columbia, Cornell, Harvard, Library of Congress, Princeton, and Stanford) to begin the transition of technical services production workflows to ones based in Linked Open Data (LOD). This first phase of the transition focuses on the development of the ability to produce metadata as LOD communally, the enhancement of the BIBFRAME ontology to encompass the multiple resource formats that academic libraries must process, and the engagement of the broader academic library community to ensure a sustainable and extensible environment. As its name implies, LD4P is focused on the immediate needs of metadata production such as ontology coverage and workflow transition. The focus of LD4P is on the identification, evaluation and adaption of existing viable tools to immediate production needs. A related project, LD4L-Labs, focuses on solutions that can be implemented in production at research libraries within the next three to five years. Their efforts focus on the enhancement and development of existing or new linked data creation and editing tools, exploration of linked data relationships, analysis of the graph to directly improve discovery, BIBFRAME ontology development, piloting efforts in URI persistence, and metadata conversion tool development needed by LD4P and the broader library community.

As part of LD4P, Stanford is leading the development of a Performed Music Ontology and is converting four key technical services production pathways from MARC-based to RDF-based in a project called the Tracer Bullets. In this panel, we will discuss our work on these projects, highlighting achievements and difficulties of current efforts, as well as plans for future work.

Philip Schreur, Stanford University
Workflow Analysis
Arcadia Falcone, Stanford University
MARC Data Enhancement and Conversion

Workshops & Tutorials

NKOS Workshop

Workshop Title: NKOS Workshop
Day/Time: Saturday, 8:30-5:30
Venue: TBA

Workshop Facilitators:

Joseph Busch, Consultant
Gail Hodges, Information International Associates


Abstract: The 11th U.S. Networked Knowledge Organization Systems (NKOS) Workshop will include: (1) Presentations, typically 20 minutes plus discussion time on work related to the themes of the workshop (see below); and (2) Demonstration on work related to the themes of the workshop.

Announcement of the Presentations and Demonstrations will be made in mid-August.

Workshop Themes:

Research Data Management

Issues related to controlled vocabularies, name authority, taxonomy, and other KOS to enable access to collections, e.g., in order to be able to replicate scientific results. What are the KOS requirements related to data storage and preservation; and communication, coordination and collaboration to support librarian and researcher needs?


The objective of linked open data is to provide distributed access to vocabularies and content that uses vocabularies. Actually using vocabularies to aggregate distributed content is a special case that reconstructs collections that are now dispersed. Examples include Renaissance artist sketchbooks, natural history collections from enlightenment humanists, etc.

Metadata Enrichment.

This theme relates to reusing existing metadata sources and adding additional controlled vocabularies, name authority, taxonomy, and other KOS to create new resources. E.g., building a new data resource based on selecting content from the Code of Federal Regulations and enriching the collection by adding new vocabularies.

Authority Control.

How does authority control work in a global linked data community? What agencies should and are willing to be responsible for the names of public agencies, companies, subsidiaries, brands and trademarks, and artists who constitute a national group based on birth place and/or area of activity.

Metrics and Quality.

How are controlled vocabularies, name authority, taxonomy and other KOS quantified and qualified? What are the appropriate dimensions of use and validation. Does Google Analytics have a role? Are there other methods and practical applications?

Life Cycle Management.

What is the common lifecycle of terms within controlled vocabularies, name authority, taxonomy and other KOS? What are the downstream impacts and best practices for handling of vocabulary changes?

Metadata 2020: Accelerating Scholarly Discovery

Workshop Title: Metadata 2020: Accelerating Scholarly Discovery
Day/Time: Saturday, 8:30-12:30
Venue: TBA

Workshop Facilitators:

Clare Dean, Community Outreach Manager, Metadata 2020
Chuck Koscher, Director of Technology, Crossref
Patricia Feeney, Product Support Manager, Crossref


Abstract: All of those who are involved in scholarly communications have the same end goal: to conduct, facilitate and/or communicate research, and have that research be discoverable. Whether they’re funders, authors, preprint servers, publishers, libraries, repositories; or the numerous tools seeking to add value through search, discovery, annotation, or analyses; so many of these organizations contribute along the way but often important details get mistyped, misrepresented, or missed out entirely.

We all face the same problem—how to include as much useful information as possible. This includes basic information but also license information, funding/grant data, ORCID iDs, organization IDs, clinical trial data, and—along the way—corrections and retractions. How can we manage the efficient entry and use of clean and complete metadata, in a way that can grow and permeate through other systems usable by all in the scholarly communications chain?

We envision a future with better metadata, not only increasing discoverability of content, but also benefiting reputation management, attribution, discoverability, efficiency, data reproducibility and reusability, in addition to future services that don’t yet exist!

A group of organizations (including Crossref, DataCite, ORCID, OpenAIRE, California Digital Library, Wikimedia, OCLC among others) have come together to rally the community around this critical issue in scholarly communications: sharing richer metadata.

Metadata 2020 is a collaboration that advocates richer, connected and reusable metadata for all research outputs with the understanding that:

  • Richer metadata fuels discoverability and innovation;

  • Connected metadata bridges the gaps between systems and communities;

  • Reusable metadata eliminates duplication of effort.

We seek input from librarians, publishers, aggregators, service providers, funders, data repositories and researchers, to share user stories and insights about the journey that metadata takes, and to help prioritize goals and tactics for Metadata 2020. Metadata 2020 is a campaign that is bigger than just one organization or sector, but a collective responsibility shared by us all.

This workshop invites contributions from specialists in the librarian community to help advance the library element of a metadata maturity model. This element will contribute to a larger maturity model in service of the wider scholarly communications community.

Using Omeka S To Create and Share Cultural Heritage Linked Open Data

Workshop Title: Using Omeka S To Create and Share Cultural Heritage Linked Open Data
Day/Time: Saturday, 1:30-5:30
Venue: TBA

Tutorial Instructor:

Patrick Murray-John, Roy Rosenzweig Center for History and New Media, George Mason University


Abstract: Omeka S is a fundamental rewrite of the popular Omeka Classic web publishing system for cultural heritage organizations. In this tutorial, we will describe the decisions we made in our renewed effort to improve metadata creation and dissemination. We will also have hands-on time for participants to use Omeka S and provide feedback on our metadata creation workflow.

In 2012, the Roy Rosenzweig Center for History and New Media (RRCHNM) at George Mason University (GMU) started developing a new version of our popular open-source web-publishing platform, Omeka (Classic), that was designed specifically with the principles of Linked Open Data (LOD) in mind. Developed for medium and larger GLAMs, Omeka S uses JavaScript Object Notation-Linked Data (JSON-LD) as its native data format, which makes it possible to enmesh Omeka S in the LOD world. Every Omeka S Resource (item, item set, media) has a URI, and the core software includes the following Resource Description Framework (RDF) vocabularies, which maximizes its data interoperability with other data publishers: Dublin Core Metadata Initiative (DCMI) Terms, DCMI Type, The Bibliographic Ontology (BIBO), and The Friend of A Friend Vocabulary (FOAF). In our progress toward ensuring and maintaining interrelationships between humanities data, connectors between Omeka S and other systems will ensure that LOD is maintained. For example, the connector to Fedora fosters import of both Fedora's own vocabulary, and the W3C Recommendation Linked Open Data Vocabulary that it rests on. Together, these features prepare data in Omeka S to be fully embedded in the semantic web.

In this tutorial we will walk through these and other aspects of Omeka S Item creation, with emphasis on LOD principles. We will also look at the features of Omeka S that ease metadata input and facilitate project-defined usage and workflows. In accordance with our commitment to interoperability, we will describe how the API for Omeka S can be deployed for data exchange and sharing between many systems. Finally, we will describe how add-on modules can expand on these metadata features, including use of Library of Congress and Getty authority data, Rights Statements, and data expansion from Linked Open Data endpoints.
