Designing the Garden: Getting Grounded in Linked Data

  1. 1. Designing the Garden: Getting Grounded in Linked Data #rwlod Jenn Riley (@jenlrile) Associate Dean, Digital Initiatives McGill University
  2. 2. "Full fathom five thy father lies, Of his bones are coral made, Those are pearls that were his eyes, Nothing of him that doth fade, But doth suffer a sea-change, into something rich and strange, Sea-nymphs hourly ring his knell, Ding-dong. Hark! now I hear them, ding-dong, bell.” --Shakespeare, The Tempest #rwlod Beyond the Looking Glass, ALCTS Preconference 2015

  4. 4. 1. It’s not “our” data and “their” data – it’s one big graph. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  5. 5. It’s about the connections https://linkedjazz.org/network/
  6. 6. Graph-based world views #rwlod Beyond the Looking Glass, ALCTS Preconference 2015 http://ebiquity.umbc.edu/blogger/2015/06/06/querying-rdf-data-with-text-annotated-graphs/
  7. 7.

  8. 8.  Creating so much data!  Where the scope of “library data” ends  What it is and isn’t “our job” to do  Making “complete” descriptions ourselves  Mapping data from “other” vocabularies into “library” vocabularies This means we can stop worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  9. 9.  Learning other metadata cultures  Being Linked Data ecosystem good citizens  How the technology and the data can most effectively work together  Making connections between things  Understanding other vocabularies and communities And start worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  10. 10. 2. We can expect more intelligence in the system. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015

  12. 12. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015 Guido Reni (1575-1642) Hercules Killing the Hydra of Lerna c. 1620-1621 oil on canvas commissioned along with other scenes from the mythology of Hercules in 1617 by Ferdinando Gonzaga, for a room in the Villa Favorita in Mantua, Italy inv. 535 Musée du Louvre, Paris, France
  13. 13.  Mine usage data to enhance relevance and utility in discovery  Start from the most relevant information and provide easy means for quick expansion on demand  Coherently display conflicting information  Give indications of provenance of information What systems must do for users #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  14. 14. If we’re serious about information literacy, we have to give our users tools and then trust them. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  15. 15.  Flag dead ends for review and action  Normalize most string-based data  Highlight potentially conflicting information  Hide complexity (URIs, etc)  Mine and show candidate connections for review What systems must do for metadata maintainers #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  16. 16.  Choosing one authoritative “correct” assertion in the face of conflicting data  Whether or not a given source meets a certain standard for authority  Authorized headings, access points  And textual justifications for them  A large proportion of the data cleanup tasks we used to do  For example, the formatting of strings  But we can expect a new set of these to emerge! This means we can stop worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  17. 17.  How to enhance system algorithms  How users best interact with complicated information  Methods for automated metadata creation and cleanup  Getting large amounts of new data into the system And start worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  18. 18. 3. The information age has provided a new definition of “authority.” #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  19. 19.  Current narrative:  Libraries create good metadata!  Because we’re trained to do so  We’re consistent and follow rules  That’s what makes good data  Other people create bad data  Because it’s not consistent  Using a well built record structure is a key part of good metadata  But…  We don’t read the books we catalogue  We don’t typically have expertise in the subjects of the works we describe  Sometimes we don’t even read or speak the language those works use  Our perspective is pretty different from our users’  Number of things to describe is quickly expanding and our budgets are shrinking Let’s take a good, hard look at our “authoritative” data #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  20. 20.  Remember, we’re looking at more intelligent systems in the LD world  That can deal with inconsistency, masking it or cleaning it up  The LD graph allows us to not worry about metadata structures  So consistency and rules are no longer the primary drivers of good metadata  Which means we can turn large swaths of the creation of metadata over to domain experts Wait, it’s not about consistency and rules? #rwlod Beyond the Looking Glass, ALCTS Preconference 2015

  22. 22. If we’re serious about good metadata, we need to start from expert information. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  23. 23. We need this guy #rwlod Beyond the Looking Glass, ALCTS Preconference 2015 http://www.betterlivingthroughbeowulf.com/scholars-lose-themselves-in-their-research/

  25. 25. Really, it’s going to be OK https://xkcd.com/386/ #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  26. 26. The Linked Data community cares about provenance #rwlod Beyond the Looking Glass, ALCTS Preconference 2015 http://www.w3.org/standards/techs/provenance#w3c_all
  27. 27.  Deep research on materials for which there’s already a knowledgeable community  Descriptions being “complete”  Making sure everything is “right” This means we can stop worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  28. 28.  Mining the data that’s already out there  Promoting voices of those who engage with content  How usable systems can be built to generate Linked Data from activities real people already partake in  Seeding basic information for the rare and unique materials we hold that have never been released  Connecting data from communities operating in different languages And start worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  29. 29. 4. Our job is to tend the garden. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015

  32. 32. A new model – making connections https://thenounproject.com/term/connection/25392/
  33. 33.  “Original cataloguing” and “copy cataloguing”  Getting data into “our systems”  Doing all the work that needs to be done the first time we think about a specific item This means we can stop worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  34. 34.  Understanding the Linked Data environment  Locating large and useful datasets  Understanding vocabularies developed elsewhere  Finding good people that can analyze relationships and make new connections And start worrying about… #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  35. 35.  The data and systems are all in the cloud  Library-based discovery less important but likely still around for a while  Several ways systems can navigate the graph  Crawling  Dereferencing  Query federation  (See http://linkeddatabook.com/editions/1.0/#htoc84) So how will Linked Data systems work?
  36. 36.  This is all the way it should work  It’s going to be a while before we get there  Big effort needed to start connecting up these data sets  Data sets and tools will get better as we start using the data in this way and demand more  The library community can help to shape this evolution, but only if we fully understand and engage with the assumptions and mechanisms in play in the Linked Data community Reality check #rwlod Beyond the Looking Glass, ALCTS Preconference 2015
  37. 37.  This will be hard. But that won’t stop us.  We need to redefine our baseline.  We need to rethink what new models mean for us.  And, most importantly, we need to put the right people in positions to work through these issues and get the details settled. A sea-change? Most definitely. #rwlod Beyond the Looking Glass, ALCTS Preconference 2015 We got this.
