Tim Lebo's csv2rdf4lod is designed for repeatability and scalability. It
was developed to handle transforming the data from data.gov into RDF, and
has been set up to automatically convert thousands of datasets. We even
have one project that regularly updates conversion configurations from
github and be converted and loaded into a triple store automatically via
cron. Further, it supports dataset versioning, where you can keep multiple
versions of data around without URI collisions. It also supports re-using
conversion configurations for multiple files that share a common format.
