Description: RDF123 is an application and web service for converting data in simple spreadsheets to an RDF graph. The spreadsheets must consist of a single table with or without header rows. Users control how the spreadsheet's data is converted to RDF by constructing a graphical RDF123 template that specifies how each row in the spreadsheet is converted as well as metadata for the spreadsheet and its RDF translation. The template can map a spreadsheet cell to a new RDF node or to a literal value. Labels on the nodes in the map can be used to create blank nodes or labeled nodes, attach a XSD datatype, and invoke simple functions (e.g., string concatenation). The graph produced for the spreadsheet is the union of the sub-graphs created for each row. The template itself is stored as a valid RDF document encouraging reuse and extensibility.

The software is available in four versions:

• WIndows application
• Linux application
• Java application
• Web service

The development of RDF123 was supported by NSF Award 0326460, ITR: Science on the Semantic Web -- Prototypes in Bioinformatics.
