About

This package contrains a tabular source file with an abbreviation and name for US States, a RDF file in Turtle syntax generated after using GRefine + DERI RDF extensions reconciliation against the reference.data.gov SPARQL endpoint to determine the identity URI for each state, and finally the editing history of how the original tabular data was mapped to the output RDF data, contributing to the overall provenance (to include the CKAN History).

Each tag given has also been identified with an URI that defines it's intended use or relation semantics as a predicate key or it's value as a Subject/Object. For example, the /dataset/states has a 'primaryTopic' key with a 'State' value, where the predicate and State URI's have been given.

This package was created using the CKAN Google Refine extension from DERI.

GRefine Source Datacsv662 B
This is a simple test file, and the original tabular file loaded into GRefine with DERI RDF and CKAN extensions. The file contained only a 'State_CD' column with row cell values having 2 letter state abbreviations, and a 'State' column with row cell values having names of States. This source data file was used with the DERI GRefine RDF extension and the reference.data.gov/sparql endpoint to reconcile the given State_CD and State column header cell values as properties (like rdfs:label, rdf:type, rdfs:comment, etc.) of their corresponding identity URIs on reference.data.gov, writing out whatever additional key=value pairs (predicates and objects) we wanted to attach to each State identity URI. For some reason I haven't figured out yet, the output from GRefine / import into CKAN gave a 'null (from Google Refine)' value for this 'Description' field.
