"For the hard graft of linked data processing."
Grafter is a library, DSL and suite of tools for flexible, efficient, ETL, data transformation and processing. Its primary use is for handling Linked Data conversions from tabular data formats into RDF linked data format, but it is equally adept at handling tabular data conversions.
See the official grafter website at grafter.org for more details.
For the Grafter rationale see our blog post: The hard graft of Linked Data ETL.
Grafter is currently in the early stages of development, however we Swirrl have been using it to transform significant amounts of data for our clients within the government.
Grafter is currently an API and a small DSL for converting tabular data into Linked Data. However we have ambitious plans to develop a suite of tools on top of it. These tools are planned to include:
- Command line tools for data processing.
- Import services to load pipelines and execute predefined data transformations.
- A Graphical ETL Tool to assist non-programmers in creating data transformation pipelines.
Grafter is deployed on the standard Clojure build repository Clojars.
To use the Grafter API please add the following to your Clojure projects
project.clj file. For more details on how to do this see the leiningen build tool:
Release candidates are released as
SNAPSHOT builds and our first official release will be
0.2, this will hopefully be released in the coming weeks.
NOTE: We are currently following a
MAJOR.MINOR.PATCH versioning scheme, but are anticipating significant breaking API changes between minor versions at least until we reach
PATCH versions should be close to being backwardly compatible with previous
Releases will be tagged with an appropriate tag indicating their
