  • re provenance, there's a draft report from W3C's incubator group on this topic which might be interesting: http://www.w3.org/2005/Incubator/prov/wiki/Final_Report_Draft

  • Transcript for slides 5-6, since Slideshare doesn't have one yet:
    'Tools to support and encourage the reuse of terms, concepts, schemas, ontologies (eg., metadata registries, and more)
    Widespread, cross disciplinary adoption of a common metadata approach (Linked Data)
    Query languages for the open web (SPARQL) are not fully mature
    Trust and provenance Infrastructure 
    Nothing missing... just use RDF, Linked Data, and the open web.  The key is broad adoption, and that requires better tools and applications.  Its a social problem, not a technical problem
    The ability to identify 'universals' across languages, disciplines, and cultures - revive Ranganathan's facets?
    Terminology services have long been proposed as important services, but they are expensive to create, curate, and manage, and the economic models are weak
    Stuff that does not work is often obvious. We need usage data to see what does work, and amplify it
     
    The soundbites:
     
    The Web has what we need in infrastructure (mostly)
    The key is broad adoption of standards, conventions, and common practice

Missing pieces in_the_global_metadata_landscap

  1. 1. Missing Pieces in the  Global Metadata Landscape Stuart Weibel, Ph.D. InfoCom International Symposium Tokyo December 8, 2010
  2. 2. Fifteen years later... <ul><li>Dublin Core metadata emerged 15 years ago, and one of the major hopes of that early effort has gone unrealized: </li></ul><ul><li>   </li></ul><ul><ul><li>A world-wide, Web-wide metadata infrastructure effective  across domains, cultures, languages and political boundaries </li></ul></ul><ul><ul><li>  </li></ul></ul><ul><li>We have succeeded to a degree, but... </li></ul><ul><li>  </li></ul><ul><li>What is still missing? </li></ul>
  3. 3. Three Questions <ul><ul><li>What is the most important missing infrastructural link in establishing globally interoperable metadata systems? </li></ul></ul><ul><ul><li>Are there conceptual or theoretical impediments that remain to be solved? </li></ul></ul><ul><ul><li>What are the organizational or institutional impediments that must be overcome to improve prospects? </li></ul></ul>
  4. 4. The Respondents: Some practitioners, some theoreticians, mostly who were at DC 2010 <ul><li>Emmanuelle Bermes, BNF </li></ul><ul><li>  </li></ul><ul><li>Karen Coyle </li></ul><ul><li>  </li></ul><ul><li>Gordon Dunshire </li></ul><ul><li>Kai Eckert, Mannheim University </li></ul><ul><li>  </li></ul><ul><li>Muriel Foulonneau </li></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>  </li></ul><ul><li>Alex Haffner, DDB  </li></ul><ul><li>  </li></ul><ul><li>Diane Hillmann & Jon Phipps </li></ul><ul><li>  </li></ul><ul><li>Andy Powell, Eduserv </li></ul><ul><li>  </li></ul><ul><li>Jodi Schneider, DERI </li></ul><ul><li>  </li></ul><ul><li>Paul Walk, UKOLN </li></ul><ul><li>  </li></ul><ul><li>Jeff Young, OCLC </li></ul>
  5. 5. What is the most important missing infrastructural link for globally interoperable metadata systems? <ul><ul><li>Tools to support and encourage the reuse of terms, concepts, schemas, ontologies (eg., metadata registries, and more) </li></ul></ul><ul><ul><li>Widespread, cross disciplinary adoption of a common metadata approach (Linked Data) </li></ul></ul><ul><ul><li>Query languages for the open web (SPARQL) are not fully mature </li></ul></ul><ul><ul><li>Trust and provenance Infrastructure  </li></ul></ul><ul><ul><li>Nothing missing... just use RDF, Linked Data, and the open web.  The key is broad adoption, and that requires better tools and applications.  Its a social problem, not a technical problem </li></ul></ul>
  6. 6. Missing Infrastructure (continued) <ul><ul><li>The ability to identify 'universals' across languages, disciplines, and cultures - revive Ranganathan's facets? </li></ul></ul><ul><ul><li>Terminology services have long been proposed as important services, but they are expensive to create, curate, and manage, and the economic models are weak </li></ul></ul><ul><ul><li>Stuff that does not work is often obvious. We need usage data to see what does work, and amplify it </li></ul></ul><ul><li>  </li></ul><ul><li>The soundbites: </li></ul><ul><li>  </li></ul><ul><ul><li>The Web has what we need in infrastructure (mostly) </li></ul></ul><ul><ul><li>The key is broad adoption of standards, conventions, and common practice </li></ul></ul>
  7. 7. Are there conceptual or theoretical impediments that remain to be solved? <ul><ul><li>Better research and metrics about what works, what is used </li></ul></ul><ul><ul><li>Research on the management and use of decentralized data </li></ul></ul><ul><ul><li>Choosing vocabularies, or aligning related vocabularies is not well understood </li></ul></ul><ul><ul><li>Working across high level conceptual models (such as RDF, CIDOC, CRM) is difficult: Models are important, but they also impose create silos that are difficult to connect.  There is no universal data model  </li></ul></ul>
  8. 8. Theoretical impediments (continued) <ul><ul><li>Standardized ways to design, describe, and declare application profiles (or ontologies, or domain models) are necessary if reuse is to happen </li></ul></ul><ul><ul><li>The declaration and management of provenance information.  Mashups are fine, but we need to be able to unmash, as well, with transparent accountabilityabout the provenance of data </li></ul></ul>
  9. 9. What are the organizational or institutional impediments that must be overcome to improve prospects? <ul><li>Economic models can cripple broad use.  Metadata is costly to create, and those who create or manage it want to be paid for its use (which, in turn inhibits use, and stifles innovation) Centralized curation is important for quality and persistence, but is costly, and leads to protectionism Funding of ongoing services (metadata maintenance, terminology services, authority services) is difficult to secure, and even harder to keep going   </li></ul>
  10. 10. Institutional Impediments (continued) <ul><li>Getting organizations to move in similar directions (adopting a common model for metadata distribution or disclosure) is very difficult: Institutional inertial is always a problem, especially when the paths are less than clear. </li></ul><ul><li>Standards solutions need to be open, and created and maintained by a broad cross section of practitioners and theoreticians.  Leave domain silos and join the web! </li></ul>
  11. 11. My favorite version of the institutional impediments question  <ul><li>Fear: </li></ul><ul><ul><li>of loss of control </li></ul></ul><ul><ul><li>of commercial exploitation of commons data </li></ul></ul><ul><ul><li>Is the semantic web just another technology du jour ? </li></ul></ul><ul><li>  </li></ul><ul><li>Ignorance: </li></ul><ul><ul><li>of the power of current semantic enabling technologies  </li></ul></ul><ul><ul><li>of terminology issues - common terminologies for modeling, for example </li></ul></ul><ul><li>  </li></ul><ul><li>Bemusement: </li></ul><ul><ul><li>about modeling </li></ul></ul><ul><ul><li>lack of agreement on recommended practices </li></ul></ul>
  12. 12. The short version of this talk <ul><ul><li>Better tools and applications  </li></ul></ul><ul><ul><li>Alignment of economic models and funding with the new technological environment </li></ul></ul><ul><ul><li>Identify research and applications that will promote better sharing capabilities </li></ul></ul><ul><ul><li>Understand and address provenance issues </li></ul></ul><ul><ul><li>Improve understanding and acceptance of the benefits (and weaknesses) of data modeling </li></ul></ul><ul><ul><li>Let no proposed standard escape the critical eye of working code that solves problems </li></ul></ul>
  13. 13. どうもありがとうございました! <ul><li>Thank you for your attention </li></ul><ul><li>And thanks to all my respondents,  who kindly took the time to reply to my questions. </li></ul><ul><li>  </li></ul><ul><li>I hope I did not distort the clarity of their thinking </li></ul><ul><li>[email_address] StuartWeibel on twitter and facebook </li></ul>
