Software for creating web applications for collaborative linguistic fieldwork.
The Online Linguistic Database (OLD) is software for creating web applications dedicated to multi-user, collaborative documention of natural (and usually endangered or understudied) languages. An OLD web application helps contributors to create a consistent, structured, and highly searchable web-based repository of language data. These data consist of textual representations of linguistic examples (words, morphemes, and sentences with analyses and annotations), associated and embedded media files, and exportable representations of texts (e.g., research papers, narratives, etc.)
See a demo OLD application at www.onlinelinguisticdatabase.org.
- Multi-user, concurrent read/write access to a server-side language database.
- Interlinear glossed text (IGT) representations of data with integrated feedback on lexical consistency or morphological analyses.
- Powerful searches over the data set.
- Authentication and authorization to control access to data.
- Export to LaTeX, CSV, and plain text.
- Media file support: many-to-many associations of audio, video, and/or image with content embedded in data representations.
- IGT text creation.
- Automatic orthography conversion.
- Inventory-based transcription input validation.
Note that there are currently two distinct versions of the OLD: 0.2.X and 1.0.
Version 0.2.X is a standard Pylons web application. Its source can be found on GitHub at https://github.com/jrwdunham/old-webapp.
Version 1.0. includes functionality for creating morphological parsers, provides improved search functionality, and implements a shift to a more modular and reusable architecture (i.e., a RESTful HTTP/JSON web service with a SPA GUI). However, there is currently no GUI for the OLD 1.0. Its source can be found on GitHub at https://github.com/jrwdunham/old.
While version 0.2.X is still being maintained, primary development has moved to version 1.0.
Get, Install & Serve
When installing the OLD 0.2.X, it is recommended that you use an isolated Python environment using virtualenv. (Note that the OLD 0.2.X has been tested with Python 2.5 and 2.6, but not 2.7. Depending on your system Python version, it may be necessary to install Python 2.5 or 2.6 using pyenv or pythonbrew.) Once virtualenv is installed, issue the following commands to create the isolated environment and to make sure you are using its Python:
virtualenv env source env/bin/activate
To install with easy_install:
pip install "OnlineLinguisticDatabase==0.2.9"
To create the config file, generate the default values, and serve the application:
mkdir my_old_webapp cd my_old_webapp paster make-config onlinelinguisticdatabase production.ini paster setup-app production.ini paster serve production.ini
The default configuration (.ini) file uses a local SQLite database, which is probably fine for exploring the system initially. However, a deployed OLD 0.2.X application should use MySQL.
First login to MySQL using your root account and create a MySQL database and a user with sufficient privileges. Something like this (replacing dbname, username, and password with sensible values):
mysql> create database dbname default character set utf8; mysql> create user 'username'@'localhost' identified by 'password'; mysql> grant select, insert, update, delete, create, drop on dbname.* to 'username'@'localhost'; mysql> quit;
Then comment out the SQLite option in the OLD 0.2.X configuration file (e.g., production.ini) and uncomment the two MySQL lines, changing values as appropriate:
sqlalchemy.url = mysql://username:password@localhost:3306/dbname sqlalchemy.pool_recycle = 3600
Now the system is set up to use MySQL. Run the setup-app command again to generate the default values in the MySQL db:
paster setup-app production.ini
See The Pylons Book for further details on serving and configuring Pylons-based web applications.
Running paster setup-app creates three users with the following usernames and passwords.
- username: admin, password: admin
- username: contributor, password: contributor
- username: viewer, password: viewer
Use the admin account to create a new administrator-level user and delete all of the default users before deploying an OLD application.
Note that if you are running Debian or Ubuntu and get an error like EnvironmentError: mysql_config not found after running python setup.py develop, then you probably need to install libmysqlclient-dev:
sudo apt-get install libmysqlclient-dev
If you get an error page when using the browser-based interface, re-saving the system settings should solve it. I.e., go to Settings > System Settings > Edit System Settings and click the “Save Changes” button.
