Globus simplifies research data management across multiple institutions and facilities by enabling reliable and secure data transfers without moving files to cloud storage. It allows researchers to assemble datasets, describe them with metadata, share them with collaborators, and publish them for broader discovery. The typical workflow involves a principal investigator initiating a transfer, researchers assembling and describing a dataset, a curator reviewing and publishing it, and peers discovering and downloading the shared data. Globus monitors transfers and provides access using campus credentials only requiring a web browser.

Editor's Notes
- April 22 2015 RDAP
- A scientist has just published a paper associated with his research on nanoscale materials. He now wants to go ahead and publish the data associated with this publication. Using the Globus publication system, he is able to select the Argonne community, and the Center for Nanoscale Materials (CNM) collection. He elects to publish his data He describes the submission with both publication (Dublin core) and scientific metadata The CNM collection has been preconfigured with its own storage provided at Argonne As part of this submission, a unique endpoint is created for the scientist; the endpoint is created so that only the scientist can write to it The scientist now “assembles” his dataset on this endpoint by transferring files from one or more locations (e.g. lab server, personal laptop, supercomputing facility) He can assemble this dataset over a long period of time and can return to the submission workflow when he is happy with the submission. The CNM collection has also been preconfigured with a workflow requiring that an Argonne curator must approve the submission The curator is able to view and edit the metadata and files of the dataset Once approved, the submission is published in the CNM collection with a DOI Other users (with permission to view the collection) can then discover published datasets by their DOI or using the Globus discovery interface to find datasets by their metadata These users can choose to browse published datasets and download datasets to other resources (local campus systems, personal computers, etc.)
