  Context  –  obtain  links  to  online  data  that  may  be  relevant  to  your  own  

  Discovery  –  users  can  find  your  data    by  following  links  on  other  partners’  sites  

  Reuse  –  the  Pelagios  API  provides  machine-­‐readable  representa3ons  (JSON,  RDF)  to  enable  mashups  and  other  forms  of  3rd  party  re-­‐use

How  to  link  data|  The  Pelagios  three  steps  to  heaven    

15

1.  Make  your  data  available  over  the  Web  with  stable  URIs  

2.  Map  your  place  references  to  the  Pleiades  Gaze]eer  of  the  Ancient  World1  

3.     Publish  place  references  as  RDF    

  Pelagios  considers  place    references  to  be  “annota3ons”  on  your  data  –  use  the  Open  Annota<on2  RDF  vocabulary  

  Use  Vocabulary  of  Interlinked  Datasets  (VoID)3  for  dataset  metadata  

1  hVp://pleiades.stoa.org/  2  hVp://www.openannota3on.org/spec/beta/    3  hVp://www.w3.org/TR/void/    

Warning:  that‘s  the  tough  part!  

Remember:  this  is  separate  from  your  data!  

Challenges  |  Issues  Iden3fied  So  Far…  

  Aggrega<ng  Data  –  no  two  datasets  are  the  same  (and  we  are  only  collec3ng  place  references…)  

  RDF  dumps  –  1  dumpfile  vs.  1.000s  of  dumpfiles  vs.  SPARQL  

  How  to  label  appropriately?  (references,  data  containing  the  reference)  

  Dataset  par<<ons  –  no  subsets  vs.  mul.ple  levels  of  hierarchy  

  Dataset  versioning  –  if  you  update  your  data…  

  Conceptualizing  Data  –  how  to  express  the  rela3on  between  data  &  place  

  Find  spot  vs.  origin,  “depicts”,  etc.  

  Uncertain  references  (probably made in…,  from the vicinity of…)  

  Granularity  &  vague  references  (South Italy,  Greek Islands)  

  Pelagios  has  been  taking  an  (extreme?)  “Keep  it  Simple”  approach  

  “We should grow the Web of Data, not build it” 16

17

Reflec<ons  |  Growing    a  Web  of  Data  

1.  Linked  Data  can  be  simple  and  useful  

2.  Using  a  common  vocabulary  should  precede  using  a  common  grammar  

3.  The  Web  is  a  two-­‐way  street,  not  a  broadcast  medium  

4.  We  shouldn’t  try  to  build  the  Linked  Data  Web  all  at  once  or  all  ourselves.    

  Introduce  complexity  through  simple  ini<a<ves  that  add  immediate,  mutual  benefit  

  Find  your  own  role  within  the  wider  ecology
