A tool to manage identities

Project description


A tool to manage identities.

Sorting Hat maintains an SQL database with identities coming (potentially) from different sources. Identities corresponding to the same real person can be merged in the same unique identity, with a unique uuid. For each unique identity, a profile can be defined, with the name and other data to show for the corresponding person by default.

In addition, each unique identity can be related to one or more affiliations, for different time periods. This will usually correspond to different organizations in which the person was employed during those time periods.

Sorting Hat is a part of the GrimoireLab toolset, which provides for Python modules and scripts to analyze data sources with information about software development, and allows to produce interactive dashboards to visualize that information.

In the context of GrimoireLab, Sorting Hat is usually run after data is retrieved with Perceval, to store the identities obtained into its database, and later merge them into unique identities (and maybe affiliate them).

Source code and contributions

All the source code is available in the Sorting Hat GitHub repository. Please, upload pull requests if you have proposals to change the source code, and open an issue if you want to report a bug, ask for a new feature, or just comment something.


usage: sortinghat [--help] [-c <file>] [-u <user>] [-p <password>]
                  [--host <host>] [--port <port>] [-d <name>]

Run 'sortinghat <command> --help' to get information about a specific command.


From pypi

You can install sortinghat as a package from the pypi repository:

$ pip install sortinghat


You can install sortinghat just by running script:

$ python install

This will install it in the python default directories in your system.

If you don’t install sortinghat with root privileges, or don’t want to install it in the default directories, you can also use the source code directory, as cloned from the main git repo. It is enough to configure your $PATH and $PYTHONPATH so that sortinghat, and the Python modules it needs, are found.

Add to your $PATH the directory which contains the sortinghat executables:

$ export PATH=$PATH:sortinghatdir/bin

In $PYHTONPATH, you need to include sortinghat as well. If sortinghatdir is the path where sortinghat is installed:

$ export PYTHONPATH=$PYTHONPATH:sortinghatdir

You are ready to use sortinghat!


You can use our image from DockerHub (grimoirelab/sortinghat) and skip the docker build step. If you prefer to build the image yourself execute:

$ docker build -t grimoirelab/sortinghat .

Next step would be to start a MySQL docker container for data storage:

$ docker run --name mysql \
             -e MYSQL_ROOT_PASSWORD=sortinghat \
             -d mysql

Run the sortinghat docker container in interactive mode:

$ docker run -i -t --rm \
             --link mysql:mysql \
             -e SORTINGHAT_DB_HOST=mysql \
             -e SORTINGHAT_DB_PASSWORD=sortinghat \
             -e SORTINGHAT_DB_DATABASE=sortinghat \
             grimoirelab/sortinghat \

Now you can initialize sortinghat with the database name sortinghat:

$ sortinghat init sortinghat

You are ready to use sortinghat and explore the commands documented below. Have fun!


Set the database parameters via the config command:

$ sortinghat config set <mysql-host>
$ sortinghat config set db.user <user>
$ sortinghat config set db.password <password>
$ sortinghat config set db.database <name>
$ sortinghat config set db.port <port>

Alternatively you can set environment variables:

$ export SORTINGHAT_DB_HOST=<mysql-host>
$ export SORTINGHAT_DB_USER=<user>
$ export SORTINGHAT_DB_PASSWORD=<password>
$ export SORTINGHAT_DB_PORT=<port>

After this initialize a new database:

$ sortinghat init <name>

Compatibility between versions

SortingHat databases previous to 0.3.0 are no longer compatible. The seed used to generate identities UUIDs changed and for that reason, these ids should be re-generated.

The next steps will restore the database generating new UUIDs for each identity but keeping the data and relationships between them.

  1. Export data

    $ sortinghat export --orgs orgs.json
    $ sortinghat export --identities identities.json
  2. Remove the database and/or create a new one with sortinghat init

  3. Load data, this will regenerate the UUIDs

    $ sortinghat load orgs.json
    $ sortinghat load identities.json

Basic commands

  • Add some unique identities ``` $ sortinghat add –name “John Smith” –email “” –username “jsmith” –source scm New identity a9b403e150dd4af8953a52a4bb841051e4b705d9 to a9b403e150dd4af8953a52a4bb841051e4b705d9
