Hello J, It's hard to make broad comparisons between DSpace and Fedora as the systems are so very different in nature. And which system you use should likely be heavily based on your local needs, expertise, and goals.
Fedora is a highly flexible data storage architecture/platform, with native linked data support. It natively speaks RDF, and the storage of all objects within Fedora can be highly customized based on local needs. However, few institutions use Fedora directly (as it requires a lot of resources to plan out your local Fedora data model, develop interfaces against it, etc). Instead, most institutions that use Fedora actually choose to use either Samvera (used to be called Hydra) or Islandora, which are full repository solutions (with their own pre-built data models and user interfaces). Samvera provides applications based on Ruby on Rails, while Islandora is essentially a flavor of Drupal (drupal.org) that is built on a Fedora backend. * https://samvera.org/ * https://islandora.ca/ DSpace is an out-of-the-box repository application, with a mind towards allowing institutions to more quickly manage their digital content and disseminate it on the web (i.e. optimized for SEO). It has a built in data model which is similar in nature to Samvera or Islandora, but is *not* based on Fedora. To make it easier to work with and install, its metadata is based on Dublin Core. The metadata is customizable, but it is not hierarchical (like RDF), and instead is limited to the format: [schema].[element].[qualifier] (you can create as many custom schemas, elements or qualifiers as you wish however). DSpace is generally considered an easier application to install/maintain (than those mentioned above), which is why it is the most widely used repository application worldwide (with over 2,000 known institutions using DSpace). DSpace is a Java web application (with a database backend), and is scalable to support large numbers of objects. (Fedora is similarly scalable) As for which is more tailored for a data repository, it also likely depends heavily on your needs/goals. As noted, Fedora is more flexible, but that flexibility requires a lot of management/staff to maintain and support. DSpace is less flexible in terms of data model or metadata, but is generally easier to maintain with less staff. There are some larger scale data repositories built on both platforms (see below). You could consider contacting one (or more) of them to talk about their experiences with either platform. DSpace-based Data Repositories: - DataDryad: https://datadryad.org/ (This system is a custom, open source product based on DSpace that is tailored more towards data repository needs) - Edinburgh Data Share: http://datashare.is.ed.ac.uk - University of Minnesota: https://conservancy.umn.edu/handle/11299/166578 Fedora-based Data Repositories: - University of Alberta, Education & Research Archive: https://era.library.ualberta.ca/ - University of Michigan, Deep Blue Data: https://deepblue.lib.umich.edu/data/ - ICPSR: https://www.datalumos.org/ and https://www.openicpsr.org/openicpsr/ I hope that gives you a decent overview from which to continue your research. - Tim On Wed, Oct 11, 2017 at 5:11 AM J.Dornbusch <[email protected]> wrote: > Hello > I am trying to determine what would be the right research data management > solution for my institution.
