This posting describes how EAD files are indexed in the "Catholic Portal" with VUFind.
VUFind is a "next-generation library catalog" or "discovery system" application. Its primary purpose is to index bibliographic metadata and provide a reader-friendly interface to the result. The heart of this process is a Solr index made up of many bibliographic-like fields. These fields are the usual suspects including a host of variants on author, title, institution, building, collection, language, format, physical description, publisher, published date, edition, description (note), contents, URL, call number, ISSN, ISBN, OCLC number, series, topic, genre, geographic, era, illustration, full text, and record type. In order for EAD files to be searchable in the Portal, they need to have their metadata extracted, the metadata needs to be mapped to Solr fields, and the metadata needs to be added to the index. The balance of this posting describes this in more detail.
