This page contains basic technical information regarding how this digital collection and web site were created. More detailed information will be made available in the weeks and months to come.
Indexing and searching
All of the information about the Hoagy Carmichael Collection has been encoded following Standard Generalized Markup Language (SGML) guidelines. There are, however, three separate sources of information for the Hoagy Carmichael collection that use three different markup languages and document type definitions (DTD):
Each of these documents has been indexed using the OpenText search engine (v5.0). The search and display mechanisms employ modified versions of perl scripts developed at the University of Michigan Humanities Text Initiative.
All items in the Hoagy Carmichael Collection were digitized at Indiana University by IU Libraries and Archives of Traditional Music staff.
The following items were scanned in the Digital Media and Image Center of the IU Digital Library Program:
Sound recordings were digitized by staff in the Archives of Traditional Music.
Lyric sheets and some typescripts were scanned as part of a previous project by the IU Libraries Preservation Department, using a Xerox Documents on Demand (XDOD) imaging workstation with Xerox DocuImage 620S scanner. This work was supported by a grant from the Indiana Humanities Council.
Information on digitization procedures is available on the Digital Media and Image Center web site.
Storage and delivery
All images are stored in the IU Digital Library Program's Fedora digital repository, running under RedHat Enterprise Linux on an IBM 8863-3RU server. A Java-based loader program was developed as part of this project to easily load images, descriptive metadata extracted from the EAD finding aid, and administrative metadata extracted from the image files themselves and from spreadsheets compiled by the scanning technicians.
Access to the images in Fedora repository is provided by a Java servlet and Java Server Pages developed by IU which use the Apache Struts framework. These servlets and JSPs operate under an Apache Tomcat server.
Sound files for Internet access are stored and served from an IBM Netfinity 5000 server running RedHat Linux 6.1 and RealServer G2 from RealNetworks.
OCLC's PURL (Persistent Uniform Resource Locator) Resolver software is used to provide unique persistent identifiers for all items in the collection.
