Ryan Scherle Dryad Digital Repository

What is Dryad?

A data repository, working closely with scientific journals. •data tightly connected to articles •broad disciplinary scope •broad interpretation of “data” •nonprofit, with Data Publication Charges

Sample content in Dryad

Why does Dryad use DSpace?

For the robust metadata model? For the extremely clean architecture? Just one reason… workflow

Issues to consider

File sizes File types Structured objects Versioning Timing of data release Additional metadata Sensitive data

File sizes

Allow submission of large files Provide curators ways to inspect large files Be aware of time required for automated processes

File types

DSpace doesn’t care, but the users do. Steer submitters to preferred types. Give curators tools to read varied types. Develop methods to look for common issues in a variety of types.

Structured objects

Changing the data model affects all parts of DSpace

•Submission •Identifiers •Curation •Item display •Search results •APIs

Articles are relatively static, but data is often reused, revised, and expanded!

Determine what constitutes a version, and how to cite it.

Timing of data release

Are data independent of the publication or synced with it?

Develop embargo policies for both metadata and bitstreams.

Technical challenges in DSpace

The most important technical issues to address when adding data to DSpace are:

•Data model •Submission/curation workflow •Processes for large files •Embargo and access control

What is Edinburgh DataShare?

● Institutional research data repository

●DSpace 5.2, with the XMLUI Mirage interface

●First deposit was accessioned in 2008

●Now contains 1,912 data items

●Very broad disciplinary spread

Metadata

●We use Dublin Core

●We mint DataCite DOIs

Big Files

Our researchers wanted to deposit files over 1 GB, which was difficult to do via the web submission form. So our developer ported the HTML5 upload facility from JSPUI to XMLUI. Now, users can upload up to 20 GB via their browser. EDINA’s code is available: https://github.com/edina/DSpace/tree/xml-html5-upload

Request-a-copy

Issues:

●Spam

●When the depositor leaves the

institution

File-level embargo

Issues:

●Policy clash

●Item embargo date ambiguous

Tombstoning

When withdrawn item

●ds.withdrawn.tombstone

File Format Registry

●343 file formats

●Scope for improvement
