1. What is Fedora Commons, and Why Should You Care? Cole Hudson and Graham Hukill

2. WARNING: Both "Fedora Commons" and "Fedora" will be used interchangeably over the course of this presentation.

13. some technical details...

14. Fedora Commons is a "system“ objects and their datastreams are the building blocks of Fedora RDF statements are used to describe relationships between objects APIs are relied on heavily for ingesting, managing, and accessing items

16. Fedora Commons is a "system" Access APIs *MySQL Mulgara RDF Database Tomcat Web Server Management APIs binary files Metadata Objects Fedora Application Web Admin Graphical Interface Web Admin Graphical Interface

17. Fedora Commons is a "system" image URL: http://fedora-commons.org/download/2.2/userdocs/server/features/images/reposvc.jpg

18. Fedora Commons is a "system“ objects and their datastreams are the building blocks of Fedora RDF statements are used to describe relationships between objects APIs are relied on heavily for ingesting, managing, and accessing items

19. INTERLUDE: objects basic atomistic building block of Fedora represents an intellectual or conceptual "item" aggregates files and pieces that make up "item" fun fact: a collection of images might is often an object too objects are stored as FOXML files: "Fedora Object XML" anatomy of a Fedora object

20. INTERLUDE: datastreams original tiff (ORIGINAL ) thumbnail (THUMB) access copy (ACCESS) RDF Statements (RELS-EXT) Dublin Core (DC) MODS (MODS) PID:: cfai:EB01a045

24. RDF: Resource Description Framework "RDF is intended for situations in which this information needs to be processed by applications, rather than being only displayed to people." -RDF primerRDF primer

25. Diary of an RDF triple In computer speak... subject = predicate = object = In human speak... The ebook object, "Sketches and Scraps", is a member of the Collection "Ramsey". "Sketches and Scraps" "Ramsey" isMemberOfCollection

26. RDF query example Query: select ?object from where ?object Reponse: info:fedora/cfai:EB02a046 info:fedora/cfai:EB02a034 info:fedora/cfai:EB01a072 info:fedora/cfai:EB02a028 info:fedora/cfai:EB01a066 etc.....

33. Aaannnd...Why Should You Care?

34. It's free as in puppies, not as in beer.

35. It's library centric. Image by Phil Bradley. CC BY-NC-SA 2.0. http://www.flickr.com/photos/philbradley/5395526390/ sizes/l/in/photostream/

36. OAI RDF Dublin Core It supports this stuff API Interfaces Digital Preservation

37. Most Importantly Though digital collections aren't getting less complex, only more. And we need software that can handle it.

39. Hurdles / Lessons Learned content modeling & unique identifiers cross-domain requests creation of FOXML ingest files comfort with RDF installation-more difficult than it first seems changing our approach multiple times understanding key concepts
