TreeBASE Submission Integration
Authors who submit content to Dryad have the option to forward their Dryad submission to TreeBASE. This saves the author time by automating the submission of data to multiple repositories, and creates an explicit link between the entries in the two repositories for easier data reuse.
Alternately, authors who initially submit content to TreeBASE may create a link from a Dryad data package to the relevant item in TreeBASE.
When a submitter decides to submit data to Dryad, and logs into the Dryad submission process, there are three simple stages to the submission process:
- Describe the publication
- Upload and describe the data files
- Approve data for publication
The TreeBASE submission integration options occur at steps two and three, depending on whether the data is first being submitted to Dryad or has already been submitted to TreeBASE.
Initial submission to Dryad
This process is the most common. The submission is initially deposited with Dryad. Data files are then forwarded from Dryad to TreeBASE.
At the second stage of the Dryad submission process, a submitter will see the option to "choose file" from their local machine. This will upload the data into Dryad. When this has happened, the submission form's page will change to indicate the file size of the uploaded data file.
If a file has been uploaded through the "choose file" interface, at the last stage in the submission process, the author will be given the option to upload the file that has been uploaded to Dryad to TreeBASE as well. Checking the checkbox and selecting TreeBASE from the repository dropdown will initiate the file's upload to TreeBASE.
The author will receive two email messages:
- A confirmation of the Dryad submission, including the DOI that Dryad has assigned to the submission.
- A notification that TreeBASE has received the forwarded data files. In this message, there will be a URL for accessing the submission within the TreeBASE system.
The author will need to follow the URL from the second message. After logging in to TreeBASE, the author will be able to complete the TreeBASE description of the data files, entering information that was not already part of the Dryad submission.
NOTE: If files are embargoed when they are deposited at Dryad, these embargo settings will not carry over to TreeBASE by default. The author must select appropriate embargo settings in each system.
Initial submission to TreeBASE
Authors may choose to deposit their data with TreeBASE first, and link the submission to a Dryad deposit.
After the TreeBASE submission has been completed, the author will login to Dryad and begin a Dryad submission. At the second stage of the Dryad submission process, the author will be asked to provide the appropriate data file(s). At this point, rather than uploading a new copy of the file(s), the author may enter an identification number for the data and the name of the repository in which the data has been submitted.
So, if the data has already been uploaded to TreeBASE, instead of uploading the data again, a submitter may just enter the TreeBASE identifier and select TreeBASE as the remote repository from the dropdown menu in the submission form. This will create a link between the Dryad data record and the data stored in the remote repository.
More detail on the TreeBASE/BagIt handshaking can be found on the Dryad BagIt Handshaking page.
This integration is based on the following technologies:
- BagIt -- A lightweight format for packaging digital content and ensuring that it is transferred intact.
- OAI-PMH -- A protocol developed by the digital library community to allow harvesting of metadata from remote repositories.
We are evaluating the SWORD protocol to manage the transfer of BagIt packages, but we have not yet determined whether SWORD will be lightweight enough to justify its use.
For information on design decisions, look at the BagIt and OAI-PMH pages listed in the Technical documentation and at the TreeBASE OAI Provider page on this wiki. We also looked at ADMIRAL: A data management infrastructure for research across the life sciences
