LEMONGRAB

Gather company data from mobygames and wikidata and build awesome research datasets and visualizations.This tool provides various commands to fetch data (via cli) and visualize it (via browser).

Requirements

• Python 3.7
• unified api
• diggrtoolbox

Prerequisites

It is recommended to install lemongrab in a virtual Python environment such as Pipenv, virtualenv, or venv.

Installation

Clone this repository and install the package.

$ git clone https://git.sc.uni-leipzig.de/ubl/diggr/general/lemongrab
$ cd lemongrab

Open lemongrab/settings.py with an editor of your choice and edit the value of DIGGR_API to the address of your instance of the UnifiedAPI. Save the file and install lemongrab.

$ pip install .

Initial setup / Create a project

Create a folder and initialize lemongrab.

$ mkdir testproject && cd testproject
$ lemongrab init

This will create two directories, one for the company_networks and on one for the required datasets. Next: Create both the wikidata mapping and the mobygames companies dataset by running:

$ lemongrab build all

Note: If you already build the datasets somewhere else, you can copy those files into the lemongrab_datasets directory and save yourself some time.

Features

The tool provides two main commands company-network and browser. The first command builds a GraphML file to be inspected (e.g. with Gephi). The second command starts a web application which can be used to inspect the companies fetched earlier.

$ lemongrab company-network -c "Japan" -p "Sony PlayStation" --roles
$ lemongrab browser

Every company network is supplied with a log file. To aggreate all logs of your project simply invoke the aggregate-logs command.

$ lemongrab aggregate-logs

This will build a CSV file in your project directory with the contents of all log files in your current project.

Usage
