How to merger two collections into one?

[Stan Orlov]

Greetings!

We have two "Graduate Theses" collections.  The main one is in the "MSVU Theses" community at http://ec.msvu.ca/xmlui/handle/10587/95, but we also created long time ago another one in the "Department of Applied Human Nutrition" community at http://ec.msvu.ca/xmlui/handle/10587/548.  Is there a simple way for us to merge the two collections into one under the main "MSVU Theses" community?

Ideally, it would be great if the existing external links to the applied human nutrition theses could still work after we move them to the main community.  We have "handle" in the URLs, so I wonder whether that is something that would need to be updated too?

Dear Stan,

If you log into DSpace web interface as an administrator and then navigate to a collection you will see the "export metadata" link on the sidebar. This will download a CSV file where one of the columns will be "collection". You can change the collection there and re-upload it to DSpace via the "import metadata" function on the web interface. The items will move to the new collection.

You also have the option to "map" items from one collection to another. When you do this the item stays in its "owning collection" and is simply mapped to the other so it appears in both.

Regarding the links to the handles, they are persistent and will always work for an item no matter where it is in the DSpace hierarchy of communities and collections. Make sure to always use the real Handle links when linking to these items in publications, social media, emails, etc because they will always work even if you change the URL or domain name of your repository: https://hdl.handle.net/10587/1915

Many  thanks, Alan!

That makes it much clearer.  After reading your reply, I examined our setup more closely together with our Archivist, who explained to me the process she uses to submit the Theses.  Turned out that she puts everything into the main Graduate Theses collection and then maps each item to the collection of the department where the student wrote the theses.  So, each item has two entries like this:

Graduate Theses

Department of Education - Graduate Theses

It's just that for the Applied Human Nutrition items it looked like this:

Graduate Theses

Graduate Theses

Thanks to you, we figured out that every thesis is mapped, we just needed to rename one collection, so we now have:

Graduate Theses

Applied Human Nutrition - Graduate Theses

And, of course, as you point out, the Handle links do not change, so we are golden!  Another crisis averted :)
