Data format for storing structured data in spreadsheet tables
Parse and manipulate structured data and metadata in a tabular format.
Metatab is a data format that allows structured metadata – the sort you’d normally store in JSON, YAML or XML – to be stored and edited in tabular forms like CSV or Excel. Metatab files look exactly like you’d expect, so they are very easy for non-technical users to read and edit, using tools they already have. Metatab is an excellent format for creating, storing and transmitting metadata. For more information about metatab, visit http://metatab.org.
What is Metatab For?
Metatab is a tabular format that allows storing metadata for demographics, health and research datasets in a tabular format. The tabular format is much easier for data creators to write and for data consumers to read, and it allows a complete data packages to be stored in a single Excel file.
Install the package from PiPy with:
$ pip install metatab
Or, install the master branch from github with:
$ pip install https://github.com/CivicKnowledge/metatab.git
Then test parsing using a remote file with:
$ metatab -j https://raw.githubusercontent.com/CivicKnowledge/metatab/master/test-data/example1.csv
Run metatab -h to get other program options.
The test-data directory has test files that also serve as examples to parse. You can either clone the repo and parse them from the files, or from the Github page for the file, click on the raw button to get raw view of the flie, then copy the URL.
Run python setup.py tests to run normal development tests. You can also run tox, which will try to run the tests with python 3.4, 3.5 and 3.6, ignoring non-existent interpreters.
Development Testing with Docker
Testing during development for other versions of Python is a bit of a pain, since you have to install the alternate version, and Tox will run all of the tests, not just the one you want.
One way to deal with this is to install Docker locally, then run the docker test container on the source directory. This is done automatically from the Makefile in metatab/test, just run:
$ cd metatab/test $ make build # to create the container image $ make test # or just .. $ make
You can also run the container shell, and run tests from the command line.
$ cd metatab/test $ make build # to create the container image $ make shell # to run bash the container
You now have a docker container where the /code directory is the metatab source dir.
Now, run tox to build the tox virtual environments, then enter the specific version you want to run tests for and activate the virtual environment.
# tox # cd .tox/py34 # source bin/activate # Activate the python 3.4 virtual env # cd ../../ # python setup.py test # Cause test deps to get installed # # python -munittest metatab.test.test_parser.TestParser.test_parse_everython # Run one test
Note that your development environment is mounted into the Docker container, so you can edit local files and test the changes in Docker.
