1.  Background  

•  at  a  minimal  level  – hold  scheme  informa<on  –  list,  describe,  iden<fy,  and  point  to  sets  of  KOS  and  other  types  of  vocabularies  available  for  use  in  informa<on  systems  and  services  

 •  at  a  higher  level  – hold  the  member  terms,  classes,  concepts,  and  rela<onships  contained  in  a  vocabulary  (either  monolingual  or  mul<lingual)  

-­‐-­‐  based  on  several  UKOLN  studies,  TRSS  project,  etc.

Efforts  of  the  NKOS  Community  NKOS  efforts  for  developing  the  specifica<on  of  the  minimum  (core)  set  of  data  elements  to  be  used  to  describe  structured  vocabularies  in  a  KOS  registry  since  1998:  •   NKOS  Registry  –  Dra1  Set  of  Thesaurus  A8ributes  of  1998  

(NKOS,  1998)  •  Dublin  Core  (DC)-­‐based  NKOS  Registry  –  Reference  document  

for  data  elements  of  2001  (Vizine-­‐Goetz,  2001)  •  JISC  Terminology  Registry  Scoping  Study  (TRSS)  report  (Golub  

and  Tudhope,  2008)  •  DCMI-­‐NKOS  Applica<on  Profile  Task  Group  established  in  

2009  (Zeng  &  Hodge,  2011)  •  developing  a  Dublin  Core  applica<on  profile  for  describing  and  accessing  KOS  resources  (KOS-­‐AP)  since  2009      

1.  Background  

Page 8: Managing&and&Sharing&KOS&& through&& …1.&Background& • ata &minimallevel – hold&scheme&informaon& – list,&describe,&iden

2.  Developing  the  KOS  Applica<on  Profile      

2.1  Use  Scenarios    2.2  The  Conceptual  Model    

o A  model  built  based  on  the  characteris<cs  of  the  KOS  resources  

o Main  en<<es  of  the  KOS-­‐AP  conceptual  mode    o Basic  rela<onships      

2.3  Core  elements        

Page 9: Managing&and&Sharing&KOS&& through&& …1.&Background& • ata &minimallevel – hold&scheme&informaon& – list,&describe,&iden

2.1  Use  Scenarios    •  The  owner(s)/creator(s)  of  a  KOS:    •  publish,  share,  and  allow  reuse  and  mapping  of  their  product(s);  

•  expose  the  KOS  product(s)      •  Other  KOS  developers    •  reuse  a  KOS;  •  get  an  example  of  good  prac<ce.    •  They  may  create  deriva<ve  works    based  on  an  exis<ng  KOS.  

•  Informa<on  retrieval  system  (IRS)  developers    •  reuse,  implement,  and  evaluate  a  KOS,    •  apply  a  KOS  to  a  collec<on  to  support    searching  and/or  naviga<on.  

•  End  users  and  researchers    •  may  be  involved  in  terminology-­‐related  research  and  exploraHon  within  a  subject  domain  

•  evaluate,  align,  or  compare  KOS  resources      

Page 10: Managing&and&Sharing&KOS&& through&& …1.&Background& • ata &minimallevel – hold&scheme&informaon& – list,&describe,&iden

User  tasks  •  FIND:  reduce  the  set  of  KOS  resources  to  a  manageable  size  using  aXributes  and  rela<onships  

•  IDENTIFY:  understand  exactly  the  nature  of  the  KOS  resource  described  by  metadata  

•  SELECT:  among  the  relevant  KOS  resources  choose  the  ones  which  are  suitable  in  a  par<cular  context  

•  OBTAIN:  get  access  to  the  KOS  resource  

•  EXPLORE:  browse  the  collec<on  to  get  acquainted  with  it  and/or  locate  interes<ng  resources    

Page 11: Managing&and&Sharing&KOS&& through&& …1.&Background& • ata &minimallevel – hold&scheme&informaon& – list,&describe,&iden

•  A  model  built  based  on  the  characteris<cs  of  the  KOS  resources  

•  The  conHnuity  of  KOS  works    •  The  diversity  of  the  ‘family’  members    •  The  shared  authorship    •  The  complexity  of  rela<ons  among  KOS  resources    •  Tendency  towards  micro-­‐level  management

3.  The  KOS-­‐AP  for  Embedded  Metadata  Use    

What  an  aggregator  will  get  is  usually  manifesta<on-­‐based  

iden<fica<on,  publisher,  format,    serviceOffered,  [date]issued  

Work  and  Expression  data  would  be  with    some  elements,  e.g.:  

<tle,  subject,  kosType,  audience,    descrip<on,  language,  contact,  sizeNote,    updateFrequency,  sample  

Alterna<ve  formats  are  available  for  the  same  expression:    

 N-­‐Triples,  RDF-­‐XML,  RDFa,  turtle    

 

Q:  Would  this  mul<-­‐layered  model  work  with      html  <meta>,  microdata,  &  RDFa  on  Webpages?  

Page 23: Managing&and&Sharing&KOS&& through&& …1.&Background& • ata &minimallevel – hold&scheme&informaon& – list,&describe,&iden

Three  Templates    to  be  Tested:    

1.  html  <meta>  in  <head>  sec<on    

2.  RDFa  for  html  documents    

3.  Microdata  for  html  documents  

Page 24: Managing&and&Sharing&KOS&& through&& …1.&Background& • ata &minimallevel – hold&scheme&informaon& – list,&describe,&iden

4.  Conclusion    •  It  is  real:  a  Dublin  Core  Applica<on  Profile  for  KOS  

Resources  (KOS-­‐AP)  developed  by  a  DCMI  Task  Group  is  developed  and  will  ask  for  comments  soon.  

•  It  is  useful:  in  addi<on  to  general  uses,  it  is  essen<al  for  Linked  Data,  which  success  depends  heavily  on  using,  sharing,  and  interlinking  of  standardized  value  vocabularies.  

•  It  is  applicable  for:  –  KOS  registries,  –  RDFa,  Microdata,  html  <meta>  of  individual  KOS  websites,  &    –  other  types  of  resources  (frequently  updated,  translated,  and  derived  handbooks,  technical  manuals,  and  schemas).
