It is the mission of the Texas Digital library (TDL) to enable digital initiatives in support of research, scholarship, and learning in Texas. As a part of this mission, the TDL endeavors to collect, preserve, and disseminate scholarly materials for the benefit of both producers and consumers of academic research and scholarship. TheTexas Data Repository, TDL’s instance of the Dataverse Networksoftware, encompassing each all of the dataverses Dataverse collections of its member institutions, is the digital resource intended to address a consortium-level need for publishing, managing, and providing access to research-generated data sets. The following Digital Preservation Policy describes the extent to which the TDL will support sustainable access to the digital research data and related content deposited in the Texas Data Repository.

...

Part of the TDL’s vision in establishing a consortium Dataverse repository installation is to make research materials freely available to anyone, anywhere, and at any time. The TDL is an advocate for open access to scholarly work including research data. The incentives to researchers for publishing and preserving their research data in the Texas Data Repository are:

...

The TDL accepts the responsibility to preserve and provide access to research data, including associated metadata and documentation that is properly deposited in the Texas Data Repository. This responsibility includes the provision of digital means to preserve and ensure ongoing access to said content for a minimum period of ten years after it is deposited in the TDR Dataverse repository. Long-term preservation of TDR Dataverse repository content, beyond the ten-year retention period, is subject to the TDL’s selection criteria, appraisal of the content, and budgetary and technical support of resources necessary to meet this goal. Metadata for content removed from the TDR Dataverse repository, regardless of reason or retention period, may be preserved for an undetermined period of time after said content’s removal.

...

The TDL systems also provide security services key to basic digital preservation, namely access control, network monitoring and protection, encryption, and system updates (see Information Security Policy). There are currently no institutional limitations to the overall quantity of data that can be stored on TDL servers, only limitations on the size of individual files (4 GB) uploaded via the Texas Data Repository application and a recommendation for datasets not to exceed 10GB.
