Consideration 1 - A Dynamic Scholarly Record

•  The scholarly record is extending with a wide range of non-
   traditional assets emerging from eScience and eHumanities
   endeavors.
     •  e.g. datasets, software, ontologies, workflows, online debate,
        slides, blogs, videos, collaborative environments, etc.

•  Many of these non-traditional assets:
    •  Do not have the sense of fixity that traditional assets such as
       journal articles or books have.
    •  Have a wide range of dependencies on other assets.

•  Even traditional assets are becoming increasingly dynamic and
   dependent on other assets, which may themselves be dynamic.

What is the Scholarly Record?

     •  It becomes challenging to define what the scholarly record is: where
        does it start and where does it end?
          •  Transforming from a stack of journals or a bunch of PDF files
             into a dynamic network of interconnected assets and actors.




“An article about computational science in a scientific publication is not the
  scholarship itself, it is merely advertising of the scholarship. The actual
  scholarship is the complete software development environment, [the
  complete data] and the complete set of instructions which generated the
  figures.” David Donoho, “Wavelab and Reproducible Research,” 1995

                   EMTACL 2012, Trondheim, Norway, October 1 2012
Fixity is Challenged …

•  The ever-evolving nature of some assets challenges the notion of
   fixity as “forever frozen” and begs considering the notion of the
   “state of the scholarly record at a specific moment in time”.
     •  Evolution from the version of record to a version of the
         record.

•  Whatever the boundaries of the scholarly record are, it will be
   essential to be able to look back at certain assets in order to
   understand how findings came about.

Consideration 2 – The Web as the Infrastructure

•  For quite some time, the Web has been the conduit for scholarly
information. But, the scholarly endeavor is increasingly embedded into,
native to, the Web.
     •  From PDF to HTML.
     •  Social component: Contributors taking a central role.
     •  Machine component: Semantic, Linked Data technologies.

•  The Web is becoming the infrastructure for the Scholarly Record.
     •  Long Term Sustainability: Reuse of infrastructure (network, software,
     platforms, standards, etc.) that the entire world depends on.
     •  Integration of scholarly discourse with other Web-based discourse.

•  The special requirements of Scholarly Communication (certification,
archiving, persistence, trust, annotation, metrics, …) must be addressed in
an interoperable manner within the Web infrastructure, not in some parallel
scholarly universe.

The HTTP URI is the Identifier
•  At the core of the Web are HTTP URIs.

•  The Web-based scholarly record works because of HTTP URIs.

•  Even when persistent identifiers are assigned to assets, contributors,
and institutions they need to be instantiated as HTTP URIs in order to do
anything useful with them on the Web.
     •  cf. http://dx.doi.org/…
     •  same for ORCID, I2, pmid, etc.

•  Many non-traditional assets are born with an HTTP URI and never
obtain a persistent identifier.
     •  cf. presentations on SlideShare, software, ontologies, workflows,
     etc.

The Web Exists in the Perpetual Now

The lack of temporal capabilities of the Web has shaped our
expectations.

•  We don’t object to prior versions not being available. We tolerate
   404s.

•  Reviewer of Memento paper at WWW 2010:
    •  Is there (sic) any statistics to show that many or a good number
       of Web users should like to get obsolete data or resources

•  Web archives are destinations, not integrated in the Web browsing
   experience.

•  Archival approach and infrastructure to deal with dynamic,
   interdependent content

•  Referencing scholarly assets

•  Recreating a version of the scholarly record

Recreating a Version of the Scholarly Record
•  Is it possible to reconstruct the Web-based scholarly record as it was at
a certain point in time?

•  For example, given a paper can one see the referenced/linked assets
as they were at the time of publication of the paper?

•  The ability to reconstruct a version of the scholarly record will
become increasingly important as the scholarly endeavor and
discourse becomes increasingly dynamic and Web-based.

But … the DOI Resolver Exists in the Perpetual Now

•  The latest information indicates that the DOI redirection history is
   currently not maintained

•  The situation is aggravated by multiple consecutive redirects at
   publisher’s end (which are likely not archived because of strict
   robots.txt rules)

•  While HTTP DOIs help achieve long-term workable links, they
   exist in the Perpetual Now like the rest of the Web’s URIs

Referencing Scholarly Assets

•  With Memento, the same HTTP URI can function as the reference to
   temporally evolving resources

•  But in order to reference the appropriate temporal version, both the
   HTTP URI and the desired time are needed.
    •  Essential for referencing resources in annotations

•  A few possibilities:
    •  Express URI and time as is currently done in citations – human
       readable, not machine actionable
    •  Turn the reference into a tuple: URI and machine-actionable
       annotation of the URI – allows expressing fragments of
       resources too
    •  Use DURI scheme

Archival Approach

•  Archiving via a combination of “curated”, “at point of interaction”,
   and “in the wild” approaches:

    o    CMS, wikis, datawikis with solid versioning mechanisms can
         play a significant role as archival hubs

    o    Archiving the linked context at the time of publication (cf.
         WebCite), when submitted into institutional repository, etc.

    o    Archiving at the moment of interaction with assets: reading,
         commenting, annotating, liking, tweeting, executing, etc.

    o    Web archives come to the rescue for “in the wild” materials.

Conclusions

•  Scholarly assets are increasingly dynamic and interdependent
•  The existing scholarly archiving infrastructure is about fixity and
   boundary

•  Scholarly communication, and, as a matter of fact, the entire
   scholarly endeavor is increasingly Web-native
•  The Web exists in the perpetual now

•  This brings along significant challenges …

    Consideration 1 -A Dynamic Scholarly Record •  The scholarly record is extending with a wide range of non- traditional assets emerging from eScience and eHumanities endeavors. •  e.g. datasets, software, ontologies, workflows, online debate, slides, blogs, videos, collaborative environments, etc. •  Many of these non-traditional assets: •  Do not have the sense of fixity that traditional assets such as journal articles or books have. •  Have a wide range of dependencies on other assets. •  Even traditional assets are becoming increasingly dynamic and dependent on other assets, which may themselves be dynamic.

    What is theScholarly Record? •  It becomes challenging to define what the scholarly record is: where does it start and where does it end? •  Transforming from a stack of journals or a bunch of PDF files into a dynamic network of interconnected assets and actors. “An article about computational science in a scientific publication is not the scholarship itself, it is merely advertising of the scholarship. The actual scholarship is the complete software development environment, [the complete data] and the complete set of instructions which generated the figures.” David Donoho, “Wavelab and Reproducible Research,” 1995 Herbert Van de Sompel Paint-Yourself-In-The-Corner Infrastructure EMTACL 2012, Trondheim, Norway, October 1 2012
  • 10.
    Fixity is Challenged… •  The ever-evolving nature of some assets challenges the notion of fixity as “forever frozen” and begs considering the notion of the “state of the scholarly record at a specific moment in time”. •  Evolution from the version of record to a version of the record. •  Whatever the boundaries of the scholarly record are, it will be essential to be able to look back at certain assets in order to understand how findings came about. Herbert Van de Sompel Paint-Yourself-In-The-Corner Infrastructure EMTACL 2012, Trondheim, Norway, October 1 2012
  • 11.
    Consideration 2 –The Web as the Infrastructure •  For quite some time, the Web has been the conduit for scholarly information. But, the scholarly endeavor is increasingly embedded into, native to, the Web. •  From PDF to HTML. •  Social component: Contributors taking a central role. •  Machine component: Semantic, Linked Data technologies. •  The Web is becoming the infrastructure for the Scholarly Record. •  Long Term Sustainability: Reuse of infrastructure (network, software, platforms, standards, etc.) that the entire world depends on. •  Integration of scholarly discourse with other Web-based discourse. •  The special requirements of Scholarly Communication (certification, archiving, persistence, trust, annotation, metrics, …) must be addressed in an interoperable manner within the Web infrastructure, not in some parallel scholarly universe.

    The HTTP URIis the Identifier •  At the core of the Web are HTTP URIs. •  The Web-based scholarly record works because of HTTP URIs. •  Even when persistent identifiers are assigned to assets, contributors, and institutions they need to be instantiated as HTTP URIs in order to do anything useful with them on the Web. •  cf. http://dx.doi.org/… •  same for ORCID, I2, pmid, etc. •  Many non-traditional assets are born with an HTTP URI and never obtain a persistent identifier. •  cf. presentations on SlideShare, software, ontologies, workflows, etc. Herbert Van de Sompel Paint-Yourself-In-The-Corner Infrastructure EMTACL 2012, Trondheim, Norway, October 1 2012

    But … theDOI Resolver Exists in the Perpetual Now •  The latest information indicates that the DOI redirection history is currently not maintained •  The situation is aggravated by multiple consecutive redirects at publisher’s end (which are likely not archived because of strict robots.txt rules) •  While HTTP DOIs help achieve long-term workable links, they exist in the Perpetual Now like the rest of the Web’s URIs Herbert Van de Sompel Paint-Yourself-In-The-Corner Infrastructure EMTACL 2012, Trondheim, Norway, October 1 2012

    Referencing Scholarly Assets • With Memento, the same HTTP URI can function as the reference to temporally evolving resources •  But in order to reference the appropriate temporal version, both the HTTP URI and the desired time are needed. •  Essential for referencing resources in annotations •  A few possibilities: •  Express URI and time as is currently done in citations – human readable, not machine actionable •  Turn the reference into a tuple: URI and machine-actionable annotation of the URI – allows expressing fragments of resources too •  Use DURI scheme Herbert Van de Sompel Paint-Yourself-In-The-Corner Infrastructure EMTACL 2012, Trondheim, Norway, October 1 2012

    Archival Approach •  Archivingvia a combination of “curated”, “at point of interaction”, and “in the wild” approaches: o  CMS, wikis, datawikis with solid versioning mechanisms can play a significant role as archival hubs o  Archiving the linked context at the time of publication (cf. WebCite), when submitted into institutional repository, etc. o  Archiving at the moment of interaction with assets: reading, commenting, annotating, liking, tweeting, executing, etc. o  Web archives come to the rescue for “in the wild” materials.
