Creating a Dublin Core (DC) Document

Previous Top Next

To create a Dublin Core (DC) document in SemanticWorks, you will need an ontology of the DC vocabulary. The application folder C:/Documents and Settings/<username>/My Documents/Altova/SemanticWorks2008/SemanticWorksExamples/Tutorial contains an OWL Lite ontology of the DC vocabulary, called DCOntology.rdf.

Creating a DC document involves the following two steps, both of which are described in detail in the respective subsections:

•	Referencing the DC Ontology;

•	Creating the DC Metadata.

Note on the Dublin Core ontology delivered with SemanticWorks

The following points should be noted:

•	The ontology is an OWL Lite ontology

•	The DC vocabulary covered is the DC Simple set of 15 basic elements.

•	The DC elements have been created as properties in the ontology.

•	No datatypes have been defined for DC elements. If you wish to assign datatypes, then select the required datatype in the GUI when entering the object definition. (Note that defining the datatype in the ontology is not sufficient to create the metadata in the RDF document as that datatype.)

Note on the Dublin Core template delivered with SemanticWorks

The following points should be noted:

•	The DC template is called DCTemplate.rdf and is located in the application folder: C:/Documents and Settings/<username>/My Documents/Altova/SemanticWorks2008/SemanticWorksExamples/Tutorial.

•	The template is intended to be used as a starting point for building RDF documents providing metadata while using the DC vocabulary.

•

The template references the DC ontology (DCOntology.rdf) using an absolute path. You will need to change this absolute path so that it correctly points to the file DCOntology.rdf in the folder: C:/Documents and Settings/<username>/My Documents/Altova/SemanticWorks2008/SemanticWorksExamples/Tutorial.
