Help! I have no metadata
------------------------

Generate Metadata Templates

This example shows how GSPy can help when you are just getting started with no metadata files at all, only partially complete metadata files, or large data files and need to do the tedious task of filling out the variable metadata.

GSPy provides a ``metadata_template`` function to generate a template YAML file either for ``Survey`` for ``Dataset`` metadata. These templates contain placeholder metadata dictionaries with default values of "not_defined" to help users get started filling in their survey or data variable metadata. Below are multiple example scenarios demonstrating how to generate the desired metadata templates.

   Example snippet of what the output template YAML file contains. For a dataset's metadata template, each variable in the data file (e.g. columns in a CSV file) is given a dictionary of attributes with the default values of "not_defined" that the user can then go through and update.

Generate the Survey Metadata Template
+++++++++++++++++++++++++++++++++++++

.. GENERATED FROM PYTHON SOURCE LINES 33-34

No existing Survey metadata, start with making a generic Survey template

Partial existing Survey metadata file, generate a combined template to see what might be missing

    # Pre-existing Survey metadata file

Generate the Variable Metadata Template for My Dataset
++++++++++++++++++++++++++++++++++++++++++++++++++++++

.. GENERATED FROM PYTHON SOURCE LINES 81-82

Zero existing Dataset metadata file, start with making an empty Dataset metadata template

.. GENERATED FROM PYTHON SOURCE LINES 84-86

Pass the data file (in this case a CSV) to make the template variable-specific.
Each column in the CSV file becomes a variable by default.

.. GENERATED FROM PYTHON SOURCE LINES 86-91

.. code-block:: Python

    data_path = '..//data_files//resolve'
    data = join(data_path, 'data//Resolve.csv')
    template = Dataset.metadata_template(data)
    template.dump("template_md_resolve_empty.yml")

Combine with a partial existing Dataset metadata file

.. GENERATED FROM PYTHON SOURCE LINES 103-104

Here we have a CSV data file and a partial metadata file (missing the variable attributes)

.. GENERATED FROM PYTHON SOURCE LINES 104-107

.. code-block:: Python


    metadata = join(data_path, 'data//Resolve_data_md_without_variables.yml')








.. GENERATED FROM PYTHON SOURCE LINES 108-110

Generate the template for this CSV dataset by combining the existing
partial file with an empty template based on the dataset's variables

.. GENERATED FROM PYTHON SOURCE LINES 110-114

.. code-block:: Python


    template = Dataset.metadata_template(data, metadata)
    template.dump("template_md_resolve_partial.yml")
