Bibliographic Class
• Tools you would expect to find with bibliographic systems
• Scalability (e.g., 17 million citations in Times Index)
• Simplicity: less than an hour to put a collection online

Finding Aids (pre-Class)
• Driven by EAD application guidelines

Origins of this Work
• Mediating role of DLPS
– Host services
– MESL work
– Production responsibilities at UM (since 1996)
– Integration in Library (e.g., Preservation)
• Work with many resources
– (> 30 distinct systems; > 20 DTDs before reconciliation)

Why Open Source DL toolkit?
• Does it make sense to have $300k “products” that are essentially closed?
• Distributed development with many contributors.
• Coordinating appropriate free, open source tools with effective low-cost commercial tools
• Balancing commercial (e.g., Oracle for AuthN/AuthZ) and Open Source (mySQL for object management)
![Page 31: The Digital Library Extension Service An Open Source Production Digital Library Access System.](https://reader030.fdocuments.us/reader030/viewer/2022032606/56649eb55503460f94bbd9f6/html5/thumbnails/31.jpg)
XPAT
• low cost licensed tool
– $15k one-time
– $5k/year for support and updates
• great support/development
• high functionality
