Although EADitor and xEAC are standalone applications, there various ways to link them together.
xEAC lookups in EADitor
Personal, corporate, and family names can be looked up with the RESTful, Solr-based Atom feed in xEAC. Entity URIs are stored in the EAD finding aids and made available when the EAD is serialized into RDF.
xEAC and EADitor can be hooked into an RDF triplestore and SPARQL endpoint. Archival published from either application may be made available through the other, or any other framework that can execute SPARQL queries.
