Transcript of "What flavor of linked data is best for your collection? "

  1. 1. What  flavor  of  linked  data  is   best  for  your  collec6on?   Debra  Shapiro   UW-­‐Madison  SLIS    
  2. 2. 2   …  using  other   methods.   …  useful   It  builds  upon  standard  Web  technologies  such  as  HTTP,   RDF  and  URIs,  but  rather  than  using  them  to  serve  web   pages  for  human  readers,  it  extends  them  to  share   informaHon  in  a  way  that  can  be  read  automaHcally  by   computers.  This  enables  data  from  different  sources  to  be   connected  and  queried.

  20. 20. To  summarize:   •  Linked  data  is:   •  Method  for  gecng  authoritaHve  descripHve   data  from  Libraries,  Archives  &  Museums  out   onto  the  web,  so  that  it  can  be  recombined   with  all  the  other  data  stuff  garbage  out  there   •  Two  main  problems    brain  benders  for  LAMs   community:   •  Linked  data  is  atomized   •  Lined  data  is  dynamic   20  
  21. 21. Just  two  flavors  today   1.  RDFa/HTML  microdata   –  Schema.org   –   OCLC’s  deployment  of  Schema.org   2.  RDF/XML   – BIBFRAME   – Europeana         23  
  22. 22. What  is  Schema.org?   “ html  tags,  that  webmasters  can   use  to  markup  their  pages  in  ways   recognized  by  major  search   providers  ” 24  
  23. 23. 27  
  24. 24. 28  
  25. 25. 29  
  26. 26. 30  
  27. 27. What  is  BIBFRAME?   “In  addiHon  to  being  a  replacement  for  MARC,   BIBFRAME  serves  as  a  general  model  for   expressing  and  connecHng  bibliographic  data.   A  major  focus  of  the  iniHaHve  will  be  to   determine  a  transiHon  path  for  the  MARC  21   formats  while  preserving  a  robust  data   exchange  that  has  supported  resource  sharing   and  cataloging  cost  savings  in  recent  decades.” 31  
  28. 28. 35  
  29. 29. 36  
  30. 30. 37  
  31. 31. 38  
  32. 32. RDFa/HTML  vs.  RDF/XML   •  Linked  data  in  HTML  way  to  enrich  the  html  of  web   pages  –  that  can  be  displaying  collecHon  informaHon   –  Schema.org  originally  designed  for  e-­‐commerce;   vocabulary  being  extended  for  cultural  heritage   informaHon   –  OCLC  doing  this  automaHcally     •  RDF/XML  way  to  re-­‐encode  metadata  in  a  linked  data   consumeable  way   –  BIBFRAME  is  an  experiment  to  convert  MARC  to  linked   data  in  RDF/XML   –  ExisHng  MARC  data  can  be  batch  transformed  to   BIBFRAME;  Europeana  also  harvests  metadata  &  re-­‐ encodes   39  
  33. 33. What  I  recommend   •  Become  a  joiner  –   –  Expose  metadata   –  Big  iniHaHves  like  europeana  and  DPLA  can  ingest  all   kinds  of  metadata  –  including  MARC   –  OCLC  is  shiling  everyone  to  the  WorldShare   Metadata  CollecHon  Manager  –  MARC,  MARCXML,   MODS,  DC,  all  kinds  of  data  from  publishers  and  Hathi   Trust  …   •  Educate  yourself  –  see  bibliography   •  Advocate  for  openness   40  
  34. 34. What  I  believe   •  Don’t  lose  sleep!   •  Linked  data  is  for  discovery   •  Content,  Data  &  ProperHes  -­‐  RULE   •  <  >,  encoding,  screens  &  screens  of  RDF,  Do   not  ma[er  as  much  as  Quality  metadata  that   can  be  shared   •  CONTEXT  Linked  data  is  HUGE  opportunity  for   librarians,  archivists,  collecHon  managers     41  
  35. 35. Why  should  we  be  interested  in  doing   this  again?   •  Get  LAMs  data  out  on  the  open  web?   •  Make  Google  happy?   •  Context?   •  Openness  and  accessibility?   •  Torture  librarians  &  collecHon  managers  ….   "    All  of  the  above   42
