        <p>Baseprint document successions offer benefits beyond preprints.
This allows the research community to cite specific fixed versions
while also having the option to discover newer versions.</p>
        <p><b>STAGE</b>: Updated future edition planned. Feedback welcome.</p>

      <h2>Summary</h2>
      <p>Baseprint document successions are preserved in
  <a rel="external" href="https://en.wikipedia.org/wiki/Git">Git</a>-compatible <sup>
          <xref rid="ref-enwikiU003Agit" ref-type="bibr">1</xref>
        </sup> repositories and archives.
  Three such examples are the <a rel="external" href="https://softwareheritage.org/">Software Heritage Archive</a>,
  <a rel="external" href="https://github.com">GitHub</a>, and <a rel="external" href="https://gitlab.org">GitLab</a>.
  See the <a href="#relationship-to-git">Relationship to Git</a> section for more details.
  The data archived is the machine-readable content of a document, separated from
  how it is visually presented.
  The benefits of this separation are discussed in the <a href="#diversity-of-reading-venues">Diversity of Reading Venues</a> section.
  A key component to making this separation possible is discussed in the
  <a href="#document-succession-identifiers">Document Succession Identifiers</a> section.
  These identifiers can be used for bibliographic references similar to a
  <a rel="external" href="https://en.wikipedia.org/w/index.php?title=Digital_object_identifier">DOI</a> <sup>
          <xref rid="ref-enwikiU003Adoi" ref-type="bibr">2</xref>
        </sup>.
  This extends one of the great features of traditional academic publishing,
  namely, the ability of researchers to reference
  a static archived document long into the future.</p>

      <h2>Document Succession Identifiers</h2>
      <p>A Document Succession Identifier (DSI) <sup>
          <xref rid="ref-DSI_spec" ref-type="bibr">3</xref>
        </sup>
  is an <a rel="external" href="https://www.softwareheritage.org/2020/07/09/intrinsic-vs-extrinsic-identifiers/">intrinsic persistent identifier</a> <sup>
          <xref rid="ref-intrinsic_extrinsic_identifiers" ref-type="bibr">4</xref>
        </sup> of a Baseprint document succession.
  It is a textual identifier similar to a
  <a rel="external" href="https://en.wikipedia.org/w/index.php?title=Digital_object_identifier">DOI</a> <sup>
          <xref rid="ref-enwikiU003Adoi" ref-type="bibr">2</xref>
        </sup>
  or a web address URL.
  This document itself is archived as a Baseprint document succession with DSI:</p>
      <pre>dsi:wk1LzCaCSKkIvLAYObAvaoLNGPc</pre>
      <p>This is a <i>base DSI</i>, which identifies all snapshots within a Baseprint document succession,
  both current and future.
  Similar to textbooks and preprints,
  Baseprint document successions contain multiple editions (or versions) of a Baseprint document,
  each encoded as a
  <a rel="external" href="https://baseprints.singlesource.pub">Baseprint document snapshot</a> <sup>
          <xref rid="ref-what_is_baseprint" ref-type="bibr">5</xref>
        </sup>.
  A base DSI identifies all the editions of a document added to a Baseprint succession.
  Usually, readers are interested in the latest edition in the Baseprint succession.</p>
      <p>An edition number can follow a <i>base DSI</i> to identify a specific static edition.
  For instance:</p>
      <pre>dsi:wk1LzCaCSKkIvLAYObAvaoLNGPc/1.1</pre>

      <h2>Conclusion</h2>
      <p>As of late 2023, Baseprint successions have been
  implemented and used by the author for over a year.
