TDWG Standards hierarchy model (image from <a href="https://github.com/tdwg/vocab/blob/master/hierarchy-model.md">Standards Documentation Standard GitHub repository</a>)</p> <p>The TDWG Standards Documentation Specification (http://www.tdwg.org/standards/147) defines a hierarchical model for components of TDWG Standards (Fig. 1). At the highest level (1st level) are Standards. All TDWG Standards are linked by virtue of a common <em>publisher</em> relationship with TDWG itself. Documents and Vocabularies (2nd level) are the parts of Standards. Vocabularies are composed of Term Lists (3rd level), which correspond roughly to namespaces that define sets of terms. The Term Lists are composed of Terms (4th level), which may be Properties, Classes, or Concepts.</p> <p>Each of the levels in the standards hierarchy are linked to the level above by a <em>isPartOf</em> relationsip, and to the level below by a <em>hasPart</em> relationship.</p> <p><img src="https://github.com/tdwg/vocab/raw/master/graphics/version-model.png" alt="TDWG version model" /> Fig. 2. Version model used to describe standards-related resources (image from the <a href="https://github.com/tdwg/vocab/blob/master/sds/documentation-specification.md">Standards Documentation Specification</a>)</p> <p>Any resource in the hierarchy above can be considered to consist of an abstract resource that persists over time, referred to as a “current resource”. In Fig. 2, the arrow represents a current resource named <em>ex:resource</em>. A current resource has a <em>creation</em> date, and a last <em>modified</em> date.</p> <p>The state of current resources over time is documented by versions of that resource. The versions are “snapshots” of the resource at a particular instant in time. In Fig. 2, the vertical lines represent versions - for example the version named <code class="language-plaintext highlighter-rouge">ex:resource-2009-07-18</code>.</p> <p>The state of most properties of a current resource at the present time are shared by the most recent version of that resource. The properties of a current resource may change when a new version is issued. The <em>issued</em> date of the new version becomes the <em>modified</em> date of the current resource.</p> <p>A current resource is related to each of its versions by a <em>hasVersion</em> relationship. A version of a resource is related to its current resource by an <em>isVersionOf</em> relationship. A version is related to a previous version by a <em>replaces</em> relationship and to a subsequent version by an <em>isReplacedBy</em> relationship.</p> <h2 id="2-iri-patterns"><a name="patterns"></a>2 IRI patterns</h2> <h3 id="21-patterns-for-current-resources-in-the-standards-hierarchy"><a name="patterns-current"></a>2.1 Patterns for current resources in the standards hierarchy</h3> <p>The IRI denoting <a href="http://www.tdwg.org/">Biodiversity Information Standards (TDWG)</a> as an organization is:</p> <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>https://www.grid.ac/institutes/grid.480498.9 </code></pre></div></div> <h4 id="1st-level-iris-denoting-tdwg-standards"><strong>1st level:</strong> IRIs denoting TDWG standards</h4> <p>are in the form:</p> <div class="language-plaintext highlighter-rouge"><div class="highlight"><pre class="highlight"><code>http://www.tdwg.org/standards/nnn </code></pre></div></div> <p>where “nnn” is a number unique to a particular standard.

That file contains the primary metadata about the resources described in that folder. For example, in the <code class="language-plaintext highlighter-rouge">terms</code> directory, the file <code class="language-plaintext highlighter-rouge">terms.csv</code> is the primary metadata file. The corresponding file with name ending in “-column-mappings.csv” maps the columns in the primary metadata file to standard metadata properties (similar in function to the meta.xml file of a Darwin Core Archive). Example: <code class="language-plaintext highlighter-rouge">terms-column-mappings.csv</code>.</p> <p>The current resource directory also contains two files that contain link tables that describe one-to-many relationships between the current resource and related resources. The file with name ending in “-replacements.csv” (example: <code class="language-plaintext highlighter-rouge">terms-replacements.csv</code>) links current resources to other current resources that replace them. The file with name ending in “-versions.csv” (example: <code class="language-plaintext highlighter-rouge">terms-versions.csv</code>) links versions to their corresponding current term.</p> <p>There are other files in each directory that contain configuration information or other information necessary to generate the machine readable metadata for the resources described in that directory.</p> <h3 id="33-files-contained-in-versions-directories"><a name="directories-versions"></a>3.3 Files contained in versions directories</h3> <p>Within each folder describing versions, the primary metadata is in the file whose name corresponds to the containing directory, plus the “.csv” file extension. For example, in the directory <code class="language-plaintext highlighter-rouge">terms-versions</code>, the file <code class="language-plaintext highlighter-rouge">terms-versions.csv</code> is the primary metadata file. The file with name ending in “-column-mappings.csv” (example: <code class="language-plaintext highlighter-rouge">terms-versions-column-mappings.csv</code>) maps the columns of the primary version metadata file to standard properties. The file with name ending in “-replacements.csv” (example: <code class="language-plaintext highlighter-rouge">terms-versions-replacements.csv</code>) is a link table that links versions to versions that replace them. Other files in the directory contain configuration or other information needed to generate machine readable metadata for the versions described in the directory.</p> <h3 id="34-retrieving-machine-readable-metadata-from-the-datasets"><a name="directories-machine-readable"></a>3.4 Retrieving machine readable metadata from the datasets</h3> <p><img src="/rs.tdwg.org/index/dcat.png" alt="TDWG Data Catalog model" /></p> <p>The IRI <code class="language-plaintext highlighter-rouge">http://rs.tdwg.org/index</code> denotes the TDWG Data catalog. When dereferenced with an <code class="language-plaintext highlighter-rouge">Accept:</code> header of <code class="language-plaintext highlighter-rouge">text/html</code>, this document should be served. When dereferenced requesting <code class="language-plaintext highlighter-rouge">text/turtle</code>, <code class="language-plaintext highlighter-rouge">application/rdf+xml</code>, or <code class="language-plaintext highlighter-rouge">application/ld+json</code>, the data catalog should be served in the RDF/Turtle, RDF/XML, and JSON-LD machine-readable serializations respectively. (The machine-readable data catalogs can be retrieved using the explicit IRIs <code class="language-plaintext highlighter-rouge">http://rs-test.tdwg.org/index.ttl</code>, <code class="language-plaintext highlighter-rouge">http://rs-test.tdwg.org/index.rdf</code>, and <code class="language-plaintext highlighter-rouge">http://rs-test.tdwg.org/index.json</code>.) Note that as of 2020-02-03 the JSON-LD representation does not conform completely to the JSON-LD specification and should not be relied upon as a source of machine-readable metadata. It can, however, be consumed as generic JSON.</p> <p>The links in the machine-readable metadata can be followed to determine a <code class="language-plaintext highlighter-rouge">dcat:downloadURL</code> to retrieve a dump of each of the datasets included in the data catalog.
