Chado Light

Chado is a modular schema for handling all kinds of biological data. It is intended to be used as both a primary datastore schema as well as a warehouse-style schema. It has been implemented for PostgreSQL databases.

This module provides a simple bridge between Chado and Drupal. It allows you to map any Chado content to Drupal entities in a couple of clicks, using external entities module to directly access Chado data. No data synchronization or indexation is needed.

Features

• Easy Chado content mapping through a graphical user interface
• Multiple database support
• Chado content mapping can be modified and customized at any time
• Mapped content can include non-Chado data (either stored in Drupal or in another data source such as a file system, another database or through REST services)
• BrAPI compatible (using the BrAPI module)

Post-Installation

If the Chado schema is not stored in the same database as the Drupal one, you will need to add your database access credentials to your site "settings.php".

Additional Requirements

External Entities, Database cross-schema query API (with the PostgreSQL driver enabled), External Entities Database storage.

Recommended modules/libraries

BrAPI, External Entities Manager, External Entities Multiple Storages, Imagecache External, External Entities Views Plugin.

Similar projects

Tripal: Tripal 3 is for Drupal 7 and Tripal 4, designed for Drupal 8+, is not available yet at the time this module is being created. So there is no complete solution to serve Chado data on a Drupal 8+ site currently. However, once Tripal 4 will be out, a converter to convert Chado Light entities into Tripal entities will be considered.

External Entities Database storage: while you can use xnttdb module to serve Chado data, the admin interface requires manual SQL queries and fields need to be mapped manually, one by one.
