FIGURE 2.10: A list of type rdf:Seq in RDF
blank nodes can be abbreviated in various serializations of RDF. Containers
introduce two additional changes:
• The triples of a list are denoted by standard identifiers instead of using
specific URIs such as ex:amount in Fig. 2.7.
• It is possible to assign a class to a list, hinting at the desired (informal)
interpretation.
An example of a corresponding list is the following specification of this
book’s authors:
<rdf:Description rdf:about="http://semantic-web-book/uri">
<ex:authors>
<rdf:Seq>
<rdf:li rdf:resource="http://semantic-web-book.org/uri/Hitzler" />
<rdf:li rdf:resource="http://semantic-web-book.org/uri/Krötzsch" ...
