Duckling, the Collaboration Environment Software Suite for e-Science
Text Size: A A A

Duckling, the collaboration environment software suite for e-Science, is an Internet-based software suite developed by CERC to meet the rapid progress of the CAS e-Science. The goals of Duckling include integrating various resources such as digital hardware, software and data, and building a high efficient and easy-to-use environment over Internet for scientists distributed in different positions to enable a new mode for scientific activities.
On May 26, 2009, Duckling 1.1 was released. It takes the Duckling Markup Language (DML) developed by the CERC as its document format. By the DML, users can online edit the document more easily, and the edited pages would have a good vision effect. Duckling 1.1 provides several user templates and the UI. Moreover, the performance also was improved rapidly.
On September 8, 2009, Duckling 1.2 was released. With the PORTLET JSR286 standard, Duckling 1.2 reconstructed the Document Collaboration Tool (DCT), Collaboration Library (CLB), User Management Tool (UMT) and the Universal Communication Tool (UCT). Duckling 1.2 also published API to develop new application plugins and provided better International language support. 
On March 17 of 2010, CNIC released her first open source software, Duckling 2.0, under the Apache License Version 2.0. The Duckling source code is available as a free download on SourceForge website, the world’s largest provider of hosting for Open Source software development projects, at
