Metadata schema and elements: required, recommended, optional.

OCLC multi-site server, aggragated Blacklight catalog –

Apache Solr – java based search index. highly scalable
complications: multiple metadata formats, but variations of Dublin core.
Solr is not a relational dbase, so management of separate partners’ records in a single Solr index was issue to make it relational.

Metadata is basis of the work of DPLA. We rely on a growing network of hubs that aggregate metadata from partners, then we, in turn, aggregate the hubs’ metadata into the DPLA datastore. As we continue to grow our hub network, we have found the practical matter of how to aggregate partner metadata and deal with quality control over the resulting aggregated set becomes our biggest challenge. If your organization is interested in becoming a part of the DPLA network, or if you are interested in how the DPLA works with metadata, we will be hosting a webinar on January 22nd, at 2pm Eastern, about our workflows, and our future development in this area. The webinar will examine the aggregation best practices at two of our DPLA Service Hubs, as the basis of a conversation about metadata aggregation practices among our Hubs. In addition, DPLA has been working on some new tools for metadata aggregation and quality control that we’d like to share. We’ll preview some of our plans and hope to get feedback on future directions.
