# OpenRefine Task Runner (💎+🤖)
|
|
|
|
[](https://www.codacy.com/gh/opencultureconsulting/openrefine-task-runner/dashboard) [](https://mybinder.org/v2/gh/opencultureconsulting/openrefine-task-runner/main)
|
|
|
|
Templates for OpenRefine batch processing (import, transform, export) using the task runner [go-task](https://github.com/go-task/task) and the [openrefine-client](https://github.com/opencultureconsulting/openrefine-client) to control OpenRefine via [its HTTP API](https://docs.openrefine.org/technical-reference/openrefine-api).
|
|
|
|
The workflow is defined in [Taskfile.yml](Taskfile.yml) and can be executed either locally (`task default`) or with [GitHub Actions](.github/workflows/default.yml).
|
|
|
|
## Features
|
|
|
|
* 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](https://github.com/opencultureconsulting/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](https://docs.openrefine.org/manual/running/#reusing-operations) from given JSON file(s)
|
|
* export to CSV, TSV, HTML, XLS, XLSX, ODS
|
|
* [templating export](https://github.com/opencultureconsulting/openrefine-client#templating) 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)
|
|
|
|
## Requirements
|
|
|
|
* GNU/Linux (tested with Fedora 34)
|
|
* JAVA 8+ (for OpenRefine)
|
|
|
|
## Typical workflow
|
|
|
|
**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](http://kb.refinepro.com/2012/06/google-refine-json-and-my-notepad-or.html) 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:
|
|
|
|
```sh
|
|
task
|
|
```
|
|
|
|
* 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.
