Add this meeting to your schedule:

We have two exciting programs that will discuss strategies and workflows
for and challenges associated with large-scale metadata aggregation.

"The Other Side of Linked Data: Managing Metadata Aggregation," presented
by Diane Hillman.

Most of the current activity in the library LOD world has been on
publishing library data out of current silos. But part of the point of
linked data for libraries is that it opens up data built by others for use
within libraries, and has the potential for greater integration of library
data within the larger data world. The sticking point for most librarians
is that data building and distribution outside the familiar world of MARC
seems like a black box, the key held by others.  Traditionally, libraries
have relied on specialized system vendors to build the functionality they
needed to manage their data. But the discussions I've heard too often
result in librarians wanting vendors to tell them what they're planning,
and vendors asking librarians what they need and want. In the context of
this stalemate, it behooves both library system vendors and librarians to
explore the issues around management of more fine-grained metadata so that
an informed dialogue around requirements c
 an begin. As part of this dialogue, there are a number of questions about
goals that could be addressed:
    * Will expression in MARC (and/or RDA and/or BibFrame) be part of the
    * How does non-library data fit in (dbpedia, nytimes, amazon, onix)?
    * How does and RDFa fit into the picture?
    * Will some data be indexed and not displayed, and vice-versa?
    * Who will decide what pieces of available data will be valued and what
pieces required?
    * Will there need to be an aggregation workflow in addition to a
cataloging workflow, or are they best integrated?

To assist in discussion about what happens after those basic decisions,
Diane will discuss a framework for managing aggregation of atomic level
(fine grained) metadata. Drawing on experience aggregating metadata for the
National Science Digital Library, she will describe specific tasks,
workflow, data improvement strategies and other issues.

"Harvesting and Normalization at the Digital Public Library of America:
Lessons from a Diverse Aggregation," presented by Kristy Berry Dixon
(Digital Library of Georgia), Sandra McIntyre (Mountain West Digital
Library) and Amy Rudersdorf (Digital Public Library of America).

The Digital Public Library of America currently works with more than 21
digital collections hubs to crosswalk, enrich, and normalize their metadata
to align with the DPLA Metadata Application Profile (
Metadata is shared in a variety of formats, standards, and readiness and is
ingested and made available through the DPLA JSON-LD API ( In developing the DPLA data model, DPLA
staff worked closely with metadata designers from the Europeana Digital
Library and from leading U.S. institutions, and has refined the model since
launch in April 2013 in response to the experience of working with diverse

This talk will introduce and outline the challenges of aggregating
disparate metadata flavors from the perspective of both DPLA staff and
representative hubs. We will review next steps and emerging frontiers as
well, including improvements to normalization at the hub level and wider
adoption of controlled vocabularies and formats for geospatial metadata and
usage rights statements. Finally, we will share plans for implementing
Linked Data throughout the aggregated national network and discuss how that
will expand opportunities for DPLA and its partners.

We hope to see you in Philadelphia!
