TDL releases Vireo ETD System as open-source software

The Texas Digital Library (TDL) is pleased to announce the open-source release of its Vireo submission and management system for electronic theses and dissertations (ETDs). Developed by the TDL with partial grant funding from the Institute of Museum and Library Services, Vireo addresses all steps of the ETD process, from online submission to publication in an institutional repository.

As of September 1, 2010, Vireo became available for download on, the world’s largest open-source software development site. It is released under a New BSD License and is available at

As a result of the release, institutions and developers outside of the TDL consortium may download and use Vireo. Developers may also alter the code and submit fixes and enhancements back to the Vireo community via SourceForge. When such enhancements are submitted, TDL will evaluate and potentially integrate them into future Vireo open-source releases, which will occur twice yearly.

Information for TDL members

The release of Vireo as an open-source product will not change how TDL member institutions access and use Vireo.

  • The Texas Digital Library will continue to actively support its members’ Vireo installations through development, optional hosting, user support, and training.
  • TDL will release Vireo bug fixes and enhancements to members ahead of the release schedule for the open-source Vireo community.
  • TDL members will continue to have a voice in TDL development efforts related to Vireo through the TDL Vireo Users Group. (  
  • TDL will continue to harvest ETDs from member repositories into the federated Texas ETD Repository and preserve them in the TDL Preservation Network.
  • The release of the software may result in additional development on Vireo that will benefit members.

About Vireo

Vireo is an Electronic Thesis and Dissertation (ETD) Submission and Management System developed by the Texas Digital Library. Vireo consists of two main interfaces: (1) a student interface that allows students to easily submit their theses and dissertations online, and (2) an expert management interface that lets graduate offices and libraries move the ETD through the approval workflow and publish it in an institutional repository.

The Texas Digital Library created Vireo with partial grant funding from the Institute of Museum and Library Services (IMLS Grant Number: LG-05-07-0095-07). Vireo was developed using DSpace Manakin’s capabilities for creating new workflow functionality within DSpace repositories.
