Create RDF

Start      Previous      Next  

At this point we have everything needed to generate the RDF for each  EduRecord . We will create RDF/XML that describes each as an instance of the class vivo:EducationalTraining . This object is identified by a URI as are the educational institution conferring the degree and the recipient. Each instance is further enriched by other data properties. The special  local:weakAttribution  predicate is used when the recipient has no netid. The full transform can be found in mkEduRDF.xsl , the main parts are shown in the next two figures.


mkEduRDF.xsl Fragment 1 - Figure 15a


mkEduRDF.xsl Fragment 2 - Figure 15b

The results of this step can be found in  example/rdf/ED.rdf .

Create RDF for New Persons and Organizations

This part of the process is needed to provide RDF that describes the new people and organizations discovered in earlier steps. The transforms are mkAccPeopleRdf.xsl  and  mkAccOrgRdf.xsl  . These transforms are fairly simple and are applied to the  NewPers.xml  and  NewOrgs.xml  respectively. The output of these transformations can be found in  example/rdf  in the files  NewPers.rdf  and  NewOrgs.rdf . These RDF files must be asserted using the VIVO user interface so that the data model of Figure 2 can be traversed and so that when  Per0.xml  and  Org0.xml  are reconstructed for the next round of ingest the new people and organizations names together with their URIs are available for matching and assignment. Otherwise duplicates with different URIs are likely to be created.

Add Predicates and RDF to VIVO

The VIVO user interface should now be used to add the two new predicates to the local ontology before adding the RDF files. If this isn’t done first you won’t get another chance until the RDF in  ED.rdf  is retracted. At this point the  ED.rdf  file can be asserted, followed by the  NewPers.rdf  and  NewOrgs.rdf  files.
