OpenRefine Task Runner (💎+🤖)
Templates for OpenRefine batch processing (import, transform, export) using the task runner go-task and the openrefine-client to control OpenRefine via its HTTP API.
The workflow is defined in Taskfile.yml and can be executed either locally (
task default) or with GitHub Actions.
- basic error handling by monitoring the OpenRefine server log
- dedicated OpenRefine instance with temporary workspace (your existing OpenRefine data will not be touched)
- prevent unnecessary work by fingerprinting generated files and their sources
- the openrefine-client used here supports many core features of OpenRefine:
- import CSV, TSV, line-based TXT, fixed-width TXT, JSON or XML (and specify input options)
- apply undo/redo history from given JSON file(s)
- export to CSV, TSV, HTML, XLS, XLSX, ODS
- templating export to additional formats like JSON or XML
- works with OpenRefine 2.7, 2.8, 3.0, 3.1, 3.2, 3.3, 3.4 and 3.5
- tasks are easy to extend with additional commands (e.g. to download input data or validate results)
- GNU/Linux (tested with Fedora 34)
- JAVA 8+ (for OpenRefine)
Step 1: Do some experiments with your data (or parts of it) in the graphical user interface of OpenRefine. If you are fine with all transformation rules, extract the json code and save it as file (e.g. dedup.json).
Step 2: Configure a task to automate importing your data set, applying the json file and exporting to the required output format.
Possible automation benefits:
When you receive updated data (in the same structure), you just need to drop the input file and start the task like this:
The entire data processing (including options during import) becomes reproducible. The task configuration file can also be used for documentation through source code comments.
Metadata experts can use OpenRefine's graphical interface and IT staff can incorporate the created transformation rules into regular data processing flows.
Demo via binder
