<section id="abstract">
<p>Datasets published on the Web are accessed and experienced by consumers
in a variety of ways, but little information about these experiences is
typically conveyed. Dataset publishers many times lack feedback from
consumers about how datasets are used. Consumers lack an effective way
to discuss experiences with fellow collaborators and explore referencing
material citing the dataset. Datasets as defined by DCAT are a
collection of data, published or curated by a single agent, and
available for access or download in one or more formats. The Dataset
Usage Vocabulary (DUV) is used to describe consumer experiences,
citations, and feedback about the dataset from the human perspective. </p>
<p>By specifying a number of foundational concepts used to collect dataset
consumer feedback, experiences, and cite references associated with a
dataset, APIs can be written to support collaboration across the Web by
structurally publishing consumer opinions and experiences, and provide a
means for dataset consumers and producers advertise and search for
published open dataset usage. </p>
</section>
<section id="sotd">
<p>This document presents the most mature version of the Dataset Usage Vocabulary that could be produced in the lifespan of the <a href="/2013/dwbp/">Data on the Web Best Practices Working Group</a>. At the time of publication, it has remained stable for several months, even after receiving feedback and suggestions from the community. Further clarifications and extensions of this model may be carried out by future working groups.</p>
</section>
<section id="intro" class="informative">
<h2> Introduction</h2>
<p> The Data on the Web Best Practices working group identified
Best Practices [[DWBP]] for citing published data, conveying feedback
between consumers and publishers, and providing descriptive metadata
that provides insights to the consumer about how published datasets can
be used. The dataset usage vocabulary is viewed as an extension to
the Data Catalog (DCAT) vocabulary version 1.0 [[VOCAB-DCAT]] to fill
current existing gaps required to adequately cite, describe usage, and
convey feedback on published datasets and
distributions. <br>
<br>
Broadly speaking the vocabulary is domain-independent and open. As
an open vocabulary the DUV encourages publishers to add descriptive
metadata tailored to meet each publisher’s domain-specific needs.
When publishers and consumers exchange, combine, and reuse published
data, the DUV metadata allows usage information to be clearly identified
and cross-referenced across datasets. Because the DUV heavily
relies on vocabulary reuse descriptive metadata in many cases can be
leveraged from original vocabulary. <br>
<br>
The DUV is modular consisting of four sub-models (DCAT, citation, usage,
feedback) to support different practitioner needs. As
a result the DUV can be used in part (DCAT+citation, DCAT+usage,
DCAT+feedback) or in its entirety depending on the practitioner’s
requirements. The DCAT+usage submodel is loosely defined to either
indicate usage from an informational perspective, or if descriptive
metadata is required, the usage submodel can indicate to find this
information. Additionally, the citation submodel describing basic
electronic citation elements, bibliographic references to dataset, and
citation rationale can be independently used.<br>

<h2>Audience</h2>
<p>The <abbr title="Dataset Usage Vocabulary">DUV</abbr> is intended for
data producers and publishers interested in tracking, sharing, and
persisting consumer dataset usage. It is also intended for collaborators
who require an exchange medium to advertise and interactively convey
dataset usage. </p>
</section>
<section id="scope">
<h2>Scope</h2>
<p> The scope of the <abbr title="Dataset Usage Vocabulary">DUV</abbr>
is defined by the Data on the Web Best Practices (DWBP) Use Case
document [[DWBP-UCR]] based on the data usage requirements about
datasets. These requirements include: citing datasets on the Web,
tracking the usage of datasets, sharing feedback and rating datasets.
These requirements were derived from fourteen real world use cases
examples provided in the use case document. </p>
</section>
<section id="relationship_vocabularies">
<h2> Relationship to other Vocabularies</h2>
<h3>Vocabulary Reuse</h3>
<p>Based on DWBP the <abbr title="Dataset Usage Vocabulary">DUV</abbr>
heavily relies upon is vocabulary reuse to support citation, feedback,
and usage of datasets published on the Web. This section provides our
rationale and approach for vocabulary selection and reuse.</p>
<p>The core DUV begins with reusing the Data Catalog Vocabulary
[[VOCAB-DCAT]] <code>dcat:Dataset</code> and <code>dcat:Distribution</code>
classes and many of their related properties. In fact, the
DUV can be considered an extension of <code>the dcat:Dataset and </code><code>dcat:Distribution</code>
classes. </p>
<p>The Web Annotation Vocabulary [[Annotation-Vocab]] is used to describe <code>duv:Feedback</code>
as a subclass inheriting the behavior of <code>oa:Annotation</code>.
The intent for the <code>duv:Feedback</code> is provided by the <code>oa:motivated_by</code>
property and <code>oa:Motivation</code> subclasses (for example: <code>oa:describing</code>,
<code>oa:questioning</code>, <code>oa:replying</code>). A subset of the
Motivation instances are important to describe feedback to data
publishers, and blogs between dataset consumers. In addition to
supporting <code>duv:Feedback</code>, because the Web Annotation
vocabulary provides a generic way of annotating any Web resource, it is
recommended that Web Annotation vocabulary be used to annotate the <code>dcat:Dataset</code>
for uses beyond the scope of the DUV. </p>
<p> The Semantic Publishing and Referencing [[SPAR]] Ontologies provides a
suite of vocabularies used to related entities to reference citations,
bibliographic records, and describe the publication process along with
other related activities. The DUV directly relies upon the FRBR-aligned
Bibliographic Ontology [[FaBIO]], and Dublin Core [[DC-TERMS]]
ontologies are used to describe citations and references between
datasets and cited sources. In addition to ontologies the research
community provided basic criteria for citing data on the Web
[[MSUDataCite]]. These resources helped scope the DUV citation model
into the minimal requirements for electronic dataset publication.
Finally, data citation principles being adopted [[FORCE11-Citation]] are
also being considered to ensure the DUV is consistent with guidelines
developed by other data citation communities.</p>
<h3>Alternative Vocabulary Considerations </h3>
<p>As discussed earlier, the intention of the DUV is to be thorough enough
to offer a starting point for describing dataset usage and yet be open
to using other alternative classes and properties as required by
developers. For example, duv:Feedback the subclass of
oa:Annotation reuses the object property oa:hasBody. While the [[Annotation-Vocab]]
uses oa:TextualBody as a means to capture textual information, however
what if needed to capture feedback in alternative ways, it is highly
suggested spending time exploring resources such as the Open Knowledge
Foundation, Linked Open Vocabularies [[OKFN]] such as using the Review
vocabulary [[REV]]. This vocabulary features a very lightweight
way to specify ratings. <br>
<br>
While the focus of this document is mainly on representing the DUV using
semantic expressions, a very active effort Schema.org [[SCHEMA]]
provides lightweight data structures that can be used as markup that
commercial search engines recognize, aiding in discovery. Not only
do Schema.org and the DUV rely on many related concepts, efforts are
underway to extend the Schema.org to support additional data structures.</p>

<section id="Vocab_Overview">
<h2>Vocabulary Overview</h2>
<p>This section depicts the vocabulary in its entirety as a conceptual
model. Boxes are used to identify each class. Labeled open arrows
identify object and literal properties. White arrowheads depict class
inheritance with the parent class identified by the arrowhead.
Please note that while most of the properties are reused from other
vocabularies, they are included in the diagram to (1) reduce the
learning curve required by DUV implementers that would otherwise be
spent constantly referencing to third party vocabularies and (2) provide
a starting place to familiarize DUV implementers with the basics needed
to get them started. </p>

<section id="Citation_Model">
<h3>Citation Model</h3>
<p>The citation model was motivated by the UCR requirement <a href="http://www.w3.org/TR/dwbp-ucr/#R-Citable">
R-Citable </a><em> It should be possible to cite data on the Web.</em>
The citation model is largely based on classes, properties, and
recommended approaches taken from the SPAR Ontologies.
<!--The remainder
of the model is composed from the Open Annotation vocabulary, Dublin Core, FOAF and by newly introduced DUV properties. --></p>
<p>The citation model seeks to meet the needs of:</p>
<ol>
<li>Data consumers who cite published <code>dcat:Dataset</code> and <code>dcat:Distribution</code>
<a href="#ex1">(See Example 1)</a> by using basic bibliographic
reference criteria provided by the data publisher. To do
this, DUV extensions are added to the DCAT model in two ways:
First because <code>dcat:Dataset</code> or <code>dcat:Distribution</code>
are forms of electronic media that can be potentially cited, both
use the same citation properties. Secondly, to fill any
information gaps, new properties were created or properties from
other vocabularies were added.

<p>The table below shows how a portion of the DUV properties can be
used to form a bibliographic reference. </p>

<li>Data publishers wanting to annotate <code>dcat:Dataset</code>/<code>dcat:Distribution</code>
with bibliographic references that provide data additional insights
to data consumers <a href="#ex2">(See Example 2)</a>. Data
publishers can also annotate a dataset or distribution with
bibliographic references provided by data consumers <a href="#ex3">(See
Example 3)</a>. For example, a researcher uses a dataset for
performing some experiments and then publishes a paper with the
experimentation's results. The dataset can be annotated with the
bibliographic reference of this paper. include: <code>dcat:Dataset</code>,
<code>dcat:Distribution</code>, <code>biro:BibliographicReference</code>,
<code>fabio:Expression</code>. Properties include: <code><code>frbr:part</code>,frbr:partOf</code>,
<code>biro:references</code>, <code>biro:isReferencedBy</code>.

</li>
</ol>
<p>Note that while the DUV reuses a limited set of [[SPAR]] classes and
properties to support basic [[VOCAB-DCAT]] dataset and distribution
citation requirements, the [[SPAR]] ontologies have a richer set of
classes and properties for more advanced representations. For example
[[FaBIO]] <code>fabio:Expression</code> class has many subclasses
(e.g. <code>fabio:Policy</code>) that help characterize referenced
material. </p>

R-TrackDataUsage </a> <em>It should be possible to track the usage
of data.</em> Sharing and tracking dataset usage can help enhancing
the utility of the datasets by providing help describing how the

Usage could be considered as enabling <span style="font-style: italic;">descriptive</span>
information provided by the data publisher to help the consumer
community make use of datasets and distributions. Based on the use
cases, data usage can help provide guidance information about how to
use the dataset and tools <a href="#ex6">(See Example 6)</a> that
