Directors’ Message: The value of TDL software development

Dear TDL members,

TDL co-directors Mark McFarland and John Leggett

While the Texas Digital Library provides its member institutions with a suite of scholarly communications services today  – things like institutional repositories and online journal management tools – it is also engaged in ongoing efforts to create future digital services that meet the consortium’s collective needs for digital publication and preservation.

These eventual new services are in the hands of the TDL’s software development team, a centralized development staff that works on behalf of the entire consortium to develop technologies that benefit our members and the future of Texas scholarship.

In a traditional model, each institution would staff its own software development shop and develop its own set of experts in isolation from other institutions. By drawing on the combined resources of our members, however, the TDL takes this burden off of each individual institution.

This centralized model provides for better allocation of resources by reducing duplication of efforts, creating a center for expertise around digital library technologies, and tackling large-scale projects that each member might not have the resources to accomplish on its own.

The benefits of this centralized approach are especially evident in the development of the TDL Preservation Network. Preservation of digital assets is a key concern of all our members, but creating a geographically dispersed network for long-term storage of fragile digital assets is a large and difficult endeavor that profits from cooperation and the pooling of resources.

You can read about the work our team has already accomplished on PresNet this year in the Development Update later in this newsletter. And as we build on this work to meet the collective business needs of our members, we keep in mind the ultimate goal of ensuring the future availability of digital scholarship produced at Texas colleges and universities.

Development Update: Progress on PresNet, TxLOR in early 2011

Binary codeThe technical team employed by the TDL is a core part of the value that TDL provides to members.  Working as a centralized development staff on behalf of the consortium, the team is working on technical projects that benefit all of the fifteen members of the TDL.

Since the beginning of the year, the team has made significant progress on two key projects: the TDL Preservation Network and the Texas Learning Object Repository. It has also begun organizing work into one-week sprints (i.e. cycles) and holding public sprint reviews each Thursday afternoon, in an effort to foster an open atmosphere with TDL members about the team’s work.

TDL Preservation Network

TDL software developers began the year focused on the TDL Preservation Network. Currently, the PresNet is capable of packaging and delivering all TDL-hosted digital assets to a dark archive at the Texas Advanced Computing Center, which replicates and stores the data with its partners at geographically dispersed locations.

The TDL team has been adding more sophisticated harvesting and scheduling functionality to the foundational processes already in place. In particular, it has begun automating the decision-making process by which the PresNet decides which node of the network should perform the harvesting of content.  The team has also created a web interface for interacting with the PresNet. This new functionality remains in testing and is not yet available as a production service.

Texas Learning Object Repository

The Texas Learning Object Repository (TxLOR) is a project to create a statewide learning object repository that stores and disseminates peer-reviewed materials used in higher education instruction. TxLOR, on which TDL is working closely with investigators at UT San Antonio, is funded by the Texas Higher Education Coordinating Board and the UT System Office of Health Affairs.

An early version of the TxLOR is running on production hardware while the TDL team continues adding functionality. During development work done in February, the team added a workflow through which a peer reviewer rejects a submitted learning object and returns the object to the submitter for revision.

Additionally, the team is moving the most recent version of the TxLOR to production hardware and batch importing a set of learning objects from a prototype repository developed at University of North Texas.

Texas A&M, TDL support researchers with data management resources

Texas A&M logoA growing number of funding agencies require grantees to make their funded research openly available or to plan for managing and preserving data collected in the course of their work. One such requirement, from the National Science Foundation (NSF), requires the submission of a Data Management Plan (or DMP) to supplement any grant proposals. The requirement was announced in the fall of 2010 and affects proposals submitted on or after January 18, 2011.

Since the proposal announcement, Texas A&M University Libraries has been active in efforts to support research faculty at Texas A&M in complying with the policy. Holly Mercer, Head of Digital Services and Scholarly Communication at the Libraries, files this report on their efforts and on the TDL’s role in supporting grant-seekers:

Effective January 18 of this year, the National Science Foundation requires all grant proposals to include a data management plan. This is a change in the implementation of NSF’s long-standing policy that requires grantees to share their data within a reasonable length of time at modest cost. The specifics of the NSF policy are available on the NSF website.

At Texas A&M, the Vice President for Research and Graduate Studies tasked a data management plan committee with determining how best to support Principal Investigators (PIs) in complying with the policy. Members of the committee include representatives from the Council of Principal Investigators, research administration offices, information technology, and libraries. Because researchers at Texas A&M have several options for grant management, the committee is focusing on providing consistent information to all PIs.

The Texas A&M University Libraries is currently working to assist investigators with the storage and data sharing portion of data management plans. The Libraries, through its membership in TDL, provides services faculty can use for access to and preservation of their research. PIs can deposit data in the Texas A&M Digital Repository, and if they wish, their data can be archived using TDL’s PresNet service.  These services are not suited for all data.  For example, disciplinary repositories might be a better option for data sharing, and very large datasets might be better managed in other ways.  Still, the data management plan committee was pleased to learn that the infrastructure for data sharing already existed on campus, and that Texas A&M is part of a multi-institution, geographically distributed network for digital preservation.

The University Libraries’ Digital Services & Scholarly Communication unit began blogging (using TDL blogs) about the NSF’s DMP requirement in May 2010, and will continue to report on developments that affect the TAMU community.  Information on the Libraries’ storage and data sharing options for grant PIs is on the scholarly communication site under “Funding Agency Guidelines.”

To help libraries help their faculty comply with the policy, the TDL has developed a resource guide with general information and links to other useful resources, including the Association of Research Libraries’ “Guide for Research Libraries: The NSF Data Sharing Policy.”
