The goal of the Next Generation Data Environment is to provide a browser-based graphical interface for conversion of CSV files into RDF linked data format. Users will be able to define a schema for their conversion by dragging and dropping classes and properties from OWL ontologies directly onto a CSV data table loaded into the environment.
This week, I focused on familiarizing myself with the CSV2RDF4LOD RDF software, which acts as the backend for the graphical interface I will be working on. I have also been investigating other existing software tools for semantic annotation and linked data conversion.
My mentor also provided links to existing software for semantic annotation and converting to RDF format. I have been testing out Anzo Express (http://www.cambridgesemantics.com/products/anzo-express); the RDF extension to Google Refine (http://refine.deri.ie/); and Morpho (http://knb.ecoinformatics.org/morphoportal.jsp). Reviewing tutorials and documentation for these programs has helped me understand what capabilities are already available, as well as the advantages and limitations of each.
This week, I developed a plan for what features and capabilities we want to include in the graphical user interface. Next week, I plan to draw up some storyboards in order to plan the actual development of these facets of the interface environment.
