OpenRefine batch processing (openrefine-batch.sh)
Shell script to run OpenRefine in batch mode (import, transform, export). This bash script automatically...
- imports all data from a given directory into OpenRefine
- transforms the data by applying OpenRefine transformation rules from all json files in another given directory and
- finally exports the data in TSV (tab-separated values) format.
It orchestrates OpenRefine (server) and a python client that communicates with the OpenRefine API. By restarting the server after each process it reduces memory requirements to a minimum.
If you prefer a containerized approach, see a variation of this script for Docker below.
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 and save it as file (e.g. transform.json).
- Step 2: Put your data and the json file(s) in two different directories and execute the script. The script will automatically import all data files in OpenRefine projects, apply the transformation rules in the json files to each project and export all projects in TSV-files.
Install
Download the script and grant file permissions to execute: wget https://github.com/felixlohmeier/openrefine-batch/raw/master/openrefine-batch.sh && chmod +x openrefine-batch.sh
That's all. The script will automatically download copies of OpenRefine and the python client on first run and will tell you if something (python, java) is missing.
Usage
mkdir input
cp INPUTFILES input/
mkdir config
cp CONFIGFILES config/
./openrefine-batch.sh -a input/ -b config/ -c OUTPUT/
INPUTFILES
- any data that OpenRefine supports. CSV, TSV and line-based files should work out of the box. XML, JSON, fixed-width, XSLX and ODS need one additional input parameter (see chapter Options below)
- multiple slices of data may be transformed into a into a single file by providing a zip or tar.gz archive
- you may use hard symlinks instead of cp:
ln INPUTFILE input/
CONFIGFILES
- JSON files with OpenRefine transformation rules)
OUTPUT/
- path to directory where results and temporary data should be stored
- Transformed data will be stored in this directory in TSV (tab-separated values) format. Show results:
ls OUTPUT/*.tsv - OpenRefine stores data in directories like "1234567890123.project". You may have a look at the results by starting OpenRefine with this workspace. Delete the directories if you do not need them:
rm -r -f OUTPUT/*.project

Logging
The script prints log messages from OpenRefine server and makes use of ps to show statistics for each step. Here is a sample:
[14:46 felix ~/openrefine-batch]$ ./openrefine-batch.sh -a examples/powerhouse-museum/input/ -b examples/powerhouse-museum/config/ -c examples/powerhouse-museum/output/ -f tsv -i processQuotes=false -i guessCellValueTypes=true -RX

Docker
A variation of the shell script orchestrates a docker container for OpenRefine (server) and a docker container for the python client instead of native applications.
Install
- Install Docker and a) configure Docker to start on boot or b) start Docker on demand each time you use the script:
sudo systemctl start docker - Download the script and grant file permissions to execute:
wget https://github.com/felixlohmeier/openrefine-batch/raw/master/openrefine-batch-docker.sh && chmod +x openrefine-batch-docker.sh
Usage
mkdir input
cp INPUTFILES input/
mkdir config
cp CONFIGFILES config/
sudo ./openrefine-batch-docker.sh input/ config/ OUTPUT/
Why sudo? Non-root users can only access the Unix socket of the Docker daemon by using sudo. If you created a Docker group in Post-installation steps for Linux then you may call the script without sudo.
Todo
- howto for extracting input options from OpenRefine GUI with Firefox network monitor
- add option to delete openrefine projects in output directory
- provide more example data from other OpenRefine tutorials
