<p>
Several properties capture provenance information, including within the citation and title, but the primary link to a formal description of the project is through <a href="#Property:dataset_wasgeneratedby">prov:wasGeneratedBy</a>.
A terse description of the project is shown as a <a href="http://www.w3.org/ns/prov#Activity">prov:Activity</a>, though this would not necessarily be part of the same catalog.
Note that as the project is ongoing, the activity has no end date.
</p>
<p>
Further provenance information might be provided using the other <i>starting point properties</i> from PROV, in particular <a href="http://www.w3.org/TR/prov-o/#wasAttributedTo">prov:wasAttributedTo</a> (to link to an agent associated with the dataset production) and <a href="http://www.w3.org/TR/prov-o/#Property:wasDerivedFrom">prov:wasDerivedFrom</a> (to link to a predecessor dataset). Both of these complement Dublin Core properties already used in DCAT, as follows:

Details about how to describe the activity that generated a dataset, such as a project, initiative, mission or survey, are out of scope for this document. <a href="http://www.w3.org/ns/prov#Activity">prov:Activity</a> provides for some basic properties such as begin and end time, associated agents etc. Further details may be provided through classes defined in applications. A number of ontologies for describing projects are available, for example VIVO for academic research projects [[vivo-isf]], DOAP (Description of a Project) for software projects [[doap]], and DBPedia for general projects [[dbpedia-ont]] which are expected to be suitable for different applications.
