This will bring you to the datastream adding form.

4. Fill out the datastream adding form

• Add a datastream -

...

•  Here you will give your datastream an identification (DSID). There are a few preconfigured datastreams that are recognized by different solution packs, but your Fedora repository will accept the ingesting of datastreams with any ID - if they aren't part of the preconfigured list, they will simply exist as an appended file, without additional support by Islandora. You can check the standard list of DSIDs for a particular solution pack in

• the Solution Packs section of Chapter 5 of this manual.
• Datastream Label -

...

•  Though necessary, this label can realistically be anything you choose. Islandora doesn't recognize one label over another; this is simply a human-readable name to be appended to the datastream for quick identification.
• Upload Document -

...

•  This is the standard form to upload a file. It can vary between browsers. This is where you will choose the file to be associated with the datastream you are creating.
• Add Datastream -

•  Once everything is filled out, click this button to start the ingest process.

5. Wait for the ingest process to complete

Once the process is successfully completed, you will see the above message. You can check if your datastream has been added properly by navigating to the datastreams management page of your object and looking for it in the list:

Removing and replacing a datastream

In this example, we will be replacing the 'thumbnail' datastream of a collection, getting rid of the 'folder' icon and uploading a different image in its stead.

1. Choose the object whose datastream you would like to replace

Image Added

In this example, we will be working inside the standard Video Solution Pack collection.

2. Click the collection's 'Manage' tab

Image Added

This will bring you to the collection's management page.

3. Click the 'Datastreams' button

Image Added

This will bring you to the datastreams management page.

4. Delete the original datastream

Image Added

You can do this by clicking the 'delete' button next to the datastream you wish to delete. In this case, we will be removing the 'TN' datastream, which corresponds to the collection's thumbnail image.

Image Added

You will be asked to confirm your deletion; click the 'Delete' button to continue.

5. Fill out the datastream adding form with the same DSID as the one you just deleted

Image Added

You can get to this point by following the same steps as listed in the 'Adding new datastreams' section above.

In this case, we will be adding a new thumbnail icon using a DSID of 'TN', with an accompanying label that makes sense.

6. View your new datastream

Image Added

We can now see that our new thumbnail datastream is associated with the object we attached it to. By simply maintaining the exact same DSID upon ingest, we can replace any datastream for any object using this same method.
