OpenRefine batch processing (openrefine-batch.sh)

Shell script to run OpenRefine on Windows, Linux or Mac in batch mode (import, transform, export). This bash script automatically...

  1. imports all data from a given directory into OpenRefine
  2. transforms the data by applying OpenRefine transformation rules from all json files in another given directory and
  3. finally exports the data in TSV (tab-separated values) format.

It orchestrates a docker container for OpenRefine (server) and a docker container for a python client that communicates with the OpenRefine API. By restarting the server after each process it reduces memory requirements to a minimum.

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

Linux:

  1. Install Docker
  2. Open Terminal and enter wget https://github.com/felixlohmeier/openrefine-batch/raw/master/openrefine-batch.sh && chmod +x openrefine-batch.sh

Mac:

  1. Install Docker
  2. ...

Windows:

  1. Install Docker
  2. Install Cygwin with Bash
  3. ...

Usage

./openrefine-batch.sh input/ config/ output/

Example

clone or download GitHub repository to get example data

./openrefine-batch.sh examples/powerhouse-museum/input/ examples/powerhouse-museum/config/ examples/powerhouse-museum/output/ examples/powerhouse-museum/cross/ 4G 2.7rc1 tsv --processQuotes=false --guessCellValueTypes=true

Options

./openrefine-batch.sh $inputdir $configdir $outputdir $crossdir $ram $version $restart $inputformat $inputoptions
  1. inputdir: path to directory with source files (multiple files may be imported into a single project by providing a zip or tar.gz archive)
  2. configdir: path to directory with OpenRefine transformation rules (json files)
  3. outputdir: path to directory for exported files (and OpenRefine workspace)
  4. crossdir: path to directory with additional OpenRefine projects (will be copied to workspace before transformation step to support the cross function)
  5. ram: maximum RAM for OpenRefine java heap space (default: 4G)
  6. version: OpenRefine version (2.7rc1, 2.6rc2, 2.6rc1, dev)
  7. restart: restart docker container after each transformation to clear memory (restart-true/restart-false)
  8. inputformat: (csv, tsv, xml, json, line-based, fixed-width, xlsx, ods)
  9. inputoptions: several options provided by openrefine-client

inputoptions (mandatory for xml, json, fixed-width, xslx, ods):

  • --recordPath=RECORDPATH (xml, json): please provide path in multiple arguments without slashes, e.g. /collection/record/ should be entered like this: --recordPath=collection --recordPath=record
  • --columnWidths=COLUMNWIDTHS (fixed-width): please provide widths separated by comma (e.g. 7,5)
  • --sheets=SHEETS (xlsx, ods): please provide sheets separated by comma (e.g. 0,1), default: 0 (first sheet)

more inputoptions (optional, only together with inputformat):

  • --limit=LIMIT (all formats), default: -1
  • --includeFileSources=INCLUDEFILESOURCES (all formats), default: false
  • --trimStrings=TRIMSTRINGS (xml, json), default: false
  • --storeEmptyStrings=STOREEMPTYSTRINGS (xml, json), default: true
  • --guessCellValueTypes=GUESSCELLVALUETYPES (xml, csv, tsv, fixed-width, json), default: false
  • --encoding=ENCODING (csv, tsv, line-based, fixed-width), please provide short encoding name (e.g. UTF-8)
  • --ignoreLines=IGNORELINES (csv, tsv, line-based, fixed-width, xlsx, ods), default: -1
  • --headerLines=HEADERLINES (csv, tsv, fixed-width, xlsx, ods), default: 1
  • --skipDataLines=SKIPDATALINES (csv, tsv, line-based, fixed-width, xlsx, ods), default: 0
  • --storeBlankRows=STOREBLANKROWS (csv, tsv, line-based, fixed-width, xlsx, ods), default: true
  • --processQuotes=PROCESSQUOTES (csv, tsv), default: true
  • --storeBlankCellsAsNulls=STOREBLANKCELLSASNULLS (csv, tsv, line-based, fixed-width, xlsx, ods), default: true
  • --linesPerRow=LINESPERROW (line-based), default: 1

Logging

The script uses docker attach to print log messages from OpenRefine server and ps to show statistics for each step. Here is a sample log:
