OSM Fieldwork contains a few standalone utility programs for converting data from ODK Collect and the ODK Central server, and a few support modules. You can install from the source tree using: pip install .
or you can install the package from PyPi.org:
pip install osm-fieldwork
The make_data_extract.py program is used to extract OpenStreetMap
(OSM) data for use with the select_one_from_file function in ODK
Collect. This function allows users to select from a list of options
generated from an external file. The make_data_extract.py program
creates a data extract that can be used as an external file with the
select_one_from_file function. There is more detailed information on
the program for making data extracts here.
CSVDump.py is program converts a CSV file downloaded from ODK Central to OpenStreetMap (OSM) XML format. The tool can be useful for users who want to work with OpenStreetMap data and want to convert ODK Central data into a compatible format. There is more detailed information on the program for converting ODK to OSM here
parsers.py is a program for conflating the OSM XML file produced from CSVDump.py into with the data extract. This merges tags that have been added or changed by ODK Collect with exiting OSM data, The result can be loaded into JOSM and after validation, uploaded to OSM.
This module creates mbtiles or sqlitedb files for basemaps. It's just a wrapper around the existing sqlite3 module to create the output files.
Osmfile.py is a module that writes OSM XML files for JOSM. It assumes the data has already been converted using CSVDump. This module is only used from within CSVDump.py. OSM XML format is needed as it's the only format that supports conflation with upstream OSM data. More on writing OSM XML is here.
filter_data.py is a program for filtering data extracts. Since an extract can only include tags and values in the XLSform, thuis scans the XLSForm, and is used to remove anything not included in the choices sheet. While usually used as a module, if run standalone it can also compare an XLSForm with the taginfo database to help modify the data models.
The convert.py module is part of the osm_fieldwork package and provides functionality for converting ODK forms between different formats using a YAML configuration file. More detailed information on this module is here
This reads in the yaml config file with all the conversion information into a data structure that can be used when processing the data conversion. More detail on this module is here.
Odk2csv.py is a command-line tool that is part of the osm-fieldwork package. Its main purpose is to convert an ODK XML instance file to CSV format, which can be easily imported into ODK Central for analysis. This is primarily only used when working offline, as it removes the need to access ODK Central.

-v, --verbose - verbose output
-i INSTANCE, --instance INSTANCE - The instance file from ODK Collect
ODKDump.py is a Python module that is part of the OSM-Fieldwork toolset for converting ODK data into various formats. It is used to parse the contents of an ODK Collect Instance file into a readable format. This module currently is not finished, instead use the CSVDump.py utility instead.
ODKForm.py parses the XLSXForm, and creates a data structure so any code using this class can access the data types of each input field. This module currently is not finished. It turns out know the input data types is not probably neccesary if we stick to processing the CSV files.
ODKInstance.py parses the ODK Collect instanceXML file, and creates a data structure so any code using this class can access the collected data values. This module currently is not finished, instead use the odk2csv.py utility instead.
