EXAMPLE: Applying an N3 patch.

@prefix solid: <http://www.w3.org/ns/solid/terms#>.
@prefix ex: <http://www.example.org/terms#>.

_:rename a solid:InsertDeletePatch;
  solid:where   { ?person ex:familyName "Garcia". };
  solid:inserts { ?person ex:givenName "Alex". };
  solid:deletes { ?person ex:givenName "Claudia". }.
This N3 Patch instructs to rename Claudia Garcia into Alex Garcia, on the condition that no other Garcia family members are present in the target RDF document.

'text/n3' patchContent can use inserts, deletes and where. N3 notation is a turtle content with graph objects.
    @prefix solid: <http://www.w3.org/ns/solid/terms#>.
    @prefix : <#>.
    @prefix ex: <http://example.com#>.
    <> solid:patches <fileUrl>;
          solid:deletes { <> a :test. };
          solid:inserts { <#new> ex:temp :321; ex:temp1 :200, :300. }.

if triples <#new> ex:temp1 :250 exists. The solid:inserts clause can be expressed as :

          solid:where { ?a ex:temp1 :250. };
          solid:inserts { ?a ex:temp :321; ex:temp1 :200, :300. }.
