1. Forward in Reverse A Gentle Overview Of Forward System Architecture Eric, Mike & Steve – WiLSWorld 2010

2. Outline • Intro to Forward with Demo • Batch Processing (Backend) • Web Application (Frontend) • Challenges • Q&As throughout

3. Intro & Demo

4. http://forward.library.wisconsin.edu

5. Batch Processing

6. We have gobs & gobs of data.

7. 1) Extract it

8. 1a) ILS Data

13. Sort, Deduplicate, Merge

14. Antique Style Key By Stars*Go*Blue http://www.flickr.com/photos/artbydebora/1406682449/

15. Common Identifier = OCLC Number

16. Catalog Extract Processing Details • 14 Voyager Instances • 13M MARC bibliographic records extracted • Approximately 14 hours • Local C code • Sorted, deduplicated and merged output: • 8M records • 10GB Raw MARC data

17. Why Merge? • URLs • Formats • Holdings

18. 1b) Digital Collection Data

20. Fedora Extract Processing Details • 1 Fedora Repository • 13K “First Class” XML Objects extracted • Approximately 4 hours • Repository query language • XML output: • METS XML package • Structural XML • MODS Bibliographic XML • 41MB XML data

21. 2) Index it

22. We take raw library data and process it with MARC/XML parsing tools and local parsing rulesin order to build a Solr search index.

23. Raw data (MARC & METS XML) • Parsing libraries (Java code: marc4j, SAXParser) • Local code that defines parsing rules • Solr index

24. 1. Raw data
