About the Scholarly Data Share (SDS) service
On this page:
Overview
The Scholarly Data Share (SDS) is a managed data-sharing service developed by the UITS Research Data Services team. It provides access to large, curated research datasets stored in the Scholarly Data Archive (SDA). A lightweight web interface provides for search and browse. Data is delivered asynchronously for download to authorized users. Both restricted and open access are supported. SDS is designed for sustainability in cost and effort over time, using existing tool chains and open-source software.
System access
Each instance of the SDS service has its own access rules, ranging from being fully open to both IU researchers and the public, to restricted authorization to members of a specific team or lab. All instances of SDS are integrated with IU Login to manage authentication. IU students, faculty, staff, and affiliates with appropriate access can log into an instance of SDS using their IU username and passphrase. Others can create an IU Guest account to access SDS instances with open data or when they have been granted access by the SDS administrators.
Download data
Logged-in users can browse and search the collections in an SDS instance. Most collections can be searched using a variety of metadata. You can download items within a collection (including metadata) by selecting the link on the item page. This initiates an asynchronous job on a server that retrieves the archive file, and then notifies you via email when the file is ready to download.
Each instance of SDS has a "My Downloads" tab which lists all of your download requests, including their statuses and download links (if available). Downloads are available for 24 hours after a request is completed; downloads that are no longer available will no longer appear on the "My Downloads" tab.
Each SDS instance is integrated with the IU SDA, which provides long-term, disaster-tolerant data archival and distribution capabilities to petabytes of IU data. Because the SDA employs both disk- and tape-based storage, there may be a delay between the download request and the time the file is ready to download; depending on the size of the file, this delay could range in length from a few minutes to several hours while the SDA's robotic tape drive locates and mounts the tape(s) storing the requested file, and then transfers the data to disk.
Acknowledge grant support
The Indiana University cyberinfrastructure, managed by the Research Technologies division of UITS, is supported by funding from several grants, each of which requires you to acknowledge its support in all presentations and published works stemming from research it has helped to fund. Conscientious acknowledgment of support from past grants also enhances the chances of IU's research community securing funding from grants in the future. For the acknowledgment statement(s) required for scholarly printed works, web pages, talks, online publications, and other presentations that make use of this and/or other grant-funded systems at IU, see Sources of funding to acknowledge in published work if you use IU's research cyberinfrastructure.
