<p>The Procedure Execution ontology (PEP) defines <tt>pep:ProcedureExecutor</tt>s that implement <tt>pep:Procedure</tt> methods, and generate <tt>pep:ProcedureExecution</tt> activities. Procedures may be linked to some description of the
input and/or the output using object properties <tt>pep:hasInput</tt> and <tt>pep:hasOutput</tt>. Their executions may be linked to some description of the command and/or the result using object properties <tt>pep:hasResult</tt> and
<tt>pep:hasCommand</tt>. If the command or the result are simple RDF literals (a typed UNICODE string), then one may use datatype properties <tt>pep:hasSimpleResult</tt> and <tt>pep:hasSimpleCommand</tt> instead. Procedure executions
made by a specific procedure executor using a specific procedure can be grouped in containers. Figure below overviews the PEP ontology, and illustrates it with an example.</p>
<p><a class="externalLink" href="https://w3id.org/pep/pep-1.1.png"><img src="https://w3id.org/pep/pep-1.1.png" alt="Overview of the PEP Ontology" /></a>.</p>
<div class="section">
<h2><a name="PEP_generalizes_the_core_concepts_of_SOSASSN"></a>PEP generalizes the core concepts of SOSA/SSN</h2>
<p>The procedure execution ontology is a simple extension of the <a class="externalLink" href="https://www.w3.org/TR/vocab-ssn/">Semantic Sensor Network (SSN) Ontology</a> and its core, called <a class="externalLink" href="https://www.w3.org/TR/vocab-ssn/">Sensor, Observation, Sample, and Actuator (SOSA)</a>.
SOSA describe <tt>sosa:Sensor</tt>s that implement <tt>sosa:Procedure</tt>s and make <tt>sosa:Observation</tt>s, which are activities. In parallel to this, it describes <tt>sosa:Actuator</tt>s that implement <tt>sosa:Procedure</tt>s
and make <tt>sosa:Actuation</tt>s. The Procedure Execution ontology defines an ontology pattern as a generalization of these two parallel conceptual models, which accounts for at least one third use case: <i>Web services exposed on the web may be called to trigger the execution of some procedures</i>.
SOSA/SSN defines input, output, results, and PEP introduces the command. </p>
<p>We provide an external document to align with the <a class="externalLink" href="https://w3id.org/pep/SSNAlignment-1.1">the Semantic Sensor Network ontology</a>.</p>

<div class="section">
<h2><a name="PEP_to_describe_Web_services_that_call_lengthy_algorithms"></a>PEP to describe Web services that call lengthy algorithms</h2>
<p>PEP can be used to describe <a class="externalLink" href="http://ci.emse.fr/pep-platform/">Web containers of Web service executions</a> one can call in a RESTful way, and that consume and produce documents with a RDF data model. A
set of such containers are referred to as a <b>Process Execution Platform</b>. </p>
<p>We provide an external document to align PEP with the <a class="externalLink" href="https://w3id.org/pep/RDFPAlignment-1.1">the RDF Presentation ontology</a>. This alignment encourages to describe the input and output of Web services
using <tt>rdfp:GraphDescription</tt>, and the command and result of their execution using URIs to <tt>rdfp:RDFSource</tt>s.</p>
