2. Prizms Overview By Tim Lebo from the TWC A pipeline of tools for taking data from CSV to linked open data ready for visualizations. –CSV2RDF4LOD and Semantic Annotator for conversion –DataFAQs for quality management –LODSPeaKr by Alvero Graves for data publication 1 Organizes data with a Source-Dataset- Version schema Captures provenance information at each step of data processing Prizms on github: https://github.com/timrdf/prizms/

3. CSV to RDF CSV2RDF4LOD is a powerful tool for converting tabular data into linked open data, able to represent many complex relationships between data fields –Command-line based –Requires prior knowledge of RDF Semantic Annotator provides a graphical user interface for this converter, building up conversion parameters in the background. –Browser-based –Still in development, currently not as powerful 2

4. CSV to RDF 2 3 Data Enhancement parameters RDF

5. Hosting Data on LODSpeaKr Quick statistics for each dataset SPARQL endpoint Ability to plug in to other semantic web services, such as SADI 4

6. The Goal Allow a scientist… –to convert data from CSV to RDF –to record provenance information about the original dataset and conversion transformation –to receive RDF immediately, for use in visualizations or other semantic applications –to point collaborators to the dataset where it is hosted on the repository 5
