+ <h1 class="title">Refactor</h1>
+ <p>The Refactor is a service which allows to interpret rules in order to
perform refactoring of RDF graphs. For the refactoring the set of rules in the
recipes are interpreted and run as SPARQL CONTRUCT in which the where clause is
derived from the body of the rule and the construct clause is derived from the
head of the rule. The output of a refactoring is a transformed graph which
satisfies the constraints expressed in the rules. The refactoring in useful for
tasks of semantic harmonization of RDF graphs expressed with different
ontologies/vocabularies towards their representation with a single ontology or
vocagulary. The output of a refactoring is a transformed graph which satisfies
the constraints expressed in the rules. </p>
+<h2 id="terminology">Terminology</h2>
+<ul>
+<li>A <strong>Recipe</strong> is a set of rules defined according to a
specific task. Rules are written in a specific syntax, and can then be executed
for refactoring (as SPARQL queries) or through reasoning services.</li>
+<li><strong>Refactoring</strong> is the task aimed to perform the
transformation of RDF graphs. The transformation is driven by refactoring
rules, basically Stanbol Rules interpreted as SPARQL CONSTRUCT clauses.</li>
+<li><strong>Reasoning</strong> is the activity of interpreting axioms for
inferring new knowledge, classifying, checking the consistency of an ontology,
etc...</li>
+</ul>
+<h2 id="usage_scenarios">Usage Scenarios</h2>
+<p>Supposing we have configured the IKS (i.e. Stanbol EntityHub) in order to
fetch entities about persons from DBpedia. Now we want to represent these
entities adopting the vocabulary from schema.org and produce schemaOrg Rich
Snippets in order to provide to the IKS search engine optimization
capabilities. What we need to do is to write a recipe and calling the Refactor
via HTTP REST passing to it the recipe itself and the entities we have fetched
from Linked Data.</p>
