Libraries in a data-centered environment
- 1. Libraries in a data-centered environment Jakob Voß (GBV) Ticer Summer School, August 22th, 2012
- 2. Prolegomena The importance of Data The importance of Libraries Summary Appendices
- 4. So what about the Cloud? I It‘s a hype I It’s a buzzword (cloud = bullshit)1 I Better know exactely what is referred to by “cloud” Which notion of cloud do libraries refer to? 1 to impress and persuade, unconcerned with falsehoods (Frankfurt, 2005)
- 5. Three notions of the Cloud
- 6. Figure: Infrastructure as a Service (IaaS)
- 7. Figure: Platform as a Service (PaaS)
- 8. Figure: Software as a Service (SaaS)
- 9. Software as a Service (aka “web application”) I Software that you don’t have to install or update. I Software that hides some of its complexity. Any software is inherently more complex then the task it automates. Don’t expect software to simplify anything!
- 10. Section 2 The importance of Data
- 11. Data vs. Applications “Data matures like wine, applications like fish” — James Governor
- 12. Data vs. Applications I For immediate consumption I Requirements and business logic change I Technical developments and trends I People’s requirements change
- 13. Data vs. Applications I Can be used in different context and times, if it is well done: I respect special properties of data I respect different notions of data
- 14. Special properties of data Bits can freely be rearranged. Eventually, data I can be copied I can be modified very efficiently, without any traces or differences between “original” and “copy”.
- 15. Special properties of data Digital Collections and descriptions of data are data again.
- 16. Data challenges This is where libraries are needed! I Preservation I Authenticity I Provenance I Identity
- 17. Data challenges: Preservation I All data needs a carrier I Unsolved problem in general, but established discipline
- 18. Data challenges: Authenticity I Data modification leaves no traces I Related to preservation but more about trust
- 19. Data challenges: Provenance I Data copy leaves no traces I Digital signatures and trust (again)
- 20. Data challenges: Identity I A single bit changes the whole dataset I Which modifications matter?
- 21. Three notions of data2 Data is also becoming a hype, so better know exactely what is referred to by “data”. I Data as facts I Data as subjective observations I Data as communications 2 As identified by Ballsun-Stanton (2012)
- 22. Data as facts I Hard numbers, product of reproducible measurements, scientific facts I Used to reveal (the real) world
- 23. Data as facts in libraries I Created by libraries I Holding counts I Patron information I Formal metadata I Collected by libraries I research data
- 24. Data as subjective observations I Product of recorded observations, sense-impressions that must be filtered I Used to construct (our) reality
- 25. Data as subjective observations in libraries I Created by libraries I Subject indexing I User studies I Analysis of publication trends I Collected by libraries I research data
- 26. Data as communications I Transferred or stored sign, a container of meaning in form of sequence of bits I Used to describe (any) reality
- 27. Data as communications in libraries digital objects, electronic resources, informational objects, electronic publications, digital documents I Created by libraries I Publications you publish I Collected by libraries I Publications you collect
- 28. Data as communications/documents in libraries A document is not information but a recorded “evidence in support of a fact” (Briet, 1951),3 which can be any possible statement. This notion somehow got lost in the history of library and information science / documentation science (Ørom 2007). I Advice: Don’t mess with data as facts or as observations but treat them as documents, like other (digital) publications! 3 See Buckland (1997,1998) for an introduction.
- 29. Section 3 The importance of Libraries
- 30. What does a library do? A library collects, arranges, and makes available (published) documents (among other services) to meet user needs. This should also apply to digital documents: I collect data I arrange data I make available data
- 31. Collect data Figure: Data needs care
- 32. Figure: How many libraries store digital objects
- 33. The eResource fallacy Libraries that license eResources to be accessed from publisher sites, limit their role to temporary, intermediary retailers. I Advice: Data that cannot be copied and modifed is lost. Libraries must actually collect and process digital documents (or won’t be in the document business anymore)
- 34. Make available data I Digital collections can be made available in different forms and places at the same time I The more libraries share digital document, the more they are perceived as trustful sources of original versions.
- 37. Arrange data I Availability implies methods to link and reuse content I Reuse and connections are already done in documents I Support linking, aggregation, processing (for instance as Linked Open Data) I Track changes when reusing (revision control)

- 41. The situation I In the end all content will be digital – get used to it! I Software is inherently complex and becomes obsolete I Data is more important in the long term, if it can be used in different context and time I Simple access will not be the primary role of libraries What’s the typical reaction to data in your institution? If data activity is outsourced to “tech people”, would you also consider outsourcing book activity to “book people”?
- 42. Care for data! I Do what you do to physical documents I collect digital document I make available digital documents I arrange digital documents I Libraries can respond to the data challenges, because of: I Trust I Neutrality I Persistence I Focus on notion of data as communications instead of digging into details of research data I Ensure that documents can be used as data: I copying must be possible and easy I modification must be possible and easy
- 43. Where to start I Collect digital publications! I Start archiving public websites, blogs, mailing lists etc. I Create and manage data/document repositories (see yesterday’s talks) I Invest in preservation I Exchange digital documents with other libraries and initiatives (see following talk by Herbert van de Sompel, LOCKSS. . . ) I Provide data as accessible as possible (Open Data) I Publish your own digital publications I Allow annotating and connecting with your digital documents

- 50. What about original data from libraries? I Data not used as documents: I facts: library data (holdings, patrons, loans, formal metadata) I observations: subject metadata (descriptions) I communication: your publications I Can be used in other context and times I Example: Authority files, connected via VIAF I Good use of data refers to you as source and authority I Advice: Provide as much as possible your original data and documents. Just publish and care for this documents like any other acquisitions.
- 51. Additional made-up quotes I If libraries still care for documents, they have to care for data. I There is no complete resource management system - the library is the resource management system I Librarians don’t have to read all books, but known all books. The same applies to data: don’t understand all data as facts and as observations, but understand data as publications.
