Your First Digital Object
You followed every Deployment step and you have now a local
Archipelago instance. Great!
So what now? It is time to give your new repository a try and we feel the best way is to start by ingesting a simple Digital Object.
This guide will assume Archipelago is running on
http://localhost:8001, so if you wizardly deployed everything in a different location, please replace all
URIs with your own setup while following this guide.
- Running Archipelago (http://localhost:8001)
- 20 minutes of your time.
- Open Mind.
Start by opening
http://locahost:8001 in your favourite Web Browser.
Your Demo deployment will have a fancy Home page with some banners and a small explanation of what Archipelago is and can do. Feel free to read through that now or later.
Log in in the top left corner and use your
demo credentials from the deployment guide.
- user: demo
- pass: demo
(or whatever password you decided was easy for you to remember during the deployment phase)
Log in button.
demo user! This users has limited credentials and uses the same global theme as any anonymous user would. Still,
demo can create content, so let's use those super powers and give that a try.
You will see a new
Menu item under
Tools on the top navigation bar named
Add Content. Click it!
As you already know Archipelago is build on
Drupal 8/9, a very extensible
CMS. In practice that means you have (at least) the same functionality any Drupal deployment has and that is also true for Content Managment.
Drupal ships by default with a very flexible
Content Entity Type named
Nodes are used for creating Articles and simple Pages but also in Archipelago as
Drupal has a pretty tight integration with
Nodes and that means you get a lot of fun and useful functionality by default by using them.
Want to know more about Entities?
Article and a
Digital Object are both of type
Nodes, but each one represents a different
Content Types are also named
An individual Content, like "Black and White photograph of a kind Dog" is named a
Content Entity or more specific in this case a
Digital Object Content types in common and what puts the apart?
- Each Content Type or Bundle has a set of
Base Fieldsand also user configurable set of
Fieldsattached (or bundled together).
Articlehas a title, a Body and the option to add an image.
Digital Objecthas a title but also a special, very flexible one named
Strawberry Field(more about that later).
Fields are where you put your data into and also where your data comes from when you expose it to the world.
Nodes, as any other Content entity have Base Fields (which means you can't remove or configure them) that are used all over the place. Good examples are the
titleand also the owner, named
- Other Fields, specific to a Content Type, can be added and configured per Bundle.
Field Widgetis used to input data into a Field.
- Each field can have a
Field Formatterthat allows you to setup how it is displayed to the World.
- A set of
Field Formatters(the way you want to show your content formatted to the world) is named a
Display Mode. You can have many, create new ones and remove them, but only use one at the time.
- A set of
Field Widgets(the way you want to Create and Edit a
Node) is named a
Form Mode. You can also have many, create new ones but only use one at the time.
Each Content Type can have different Permissions (using the build in
- Each Content Type can have one or more
Display Modes. In Practice this means
Display Modesare attached to
- Each display modes can have its own Permissions
- Each Content Type can have one or more
Form Modes. In Practice this means
Form Modesare attached to
Form Modecan have its own Permissions.
There is of course a lot more to Nodes, Content Types, Formatters, Widgets and in general Content Entities but this is a good start to understand what will happen next.
Below you see all the
Content Types defined by default in Archipelago. Let's click on
Digital Object to get your first Digital Object Node.
What you see below is a
Form Mode in action. A multi-step Webform that will ingest metadata into a field of type Strawberry Field (where all the magic happens) attached to that field using a
Webform Field Widget, an editorial/advanced Block on the right side, and a
Quick Save button at the bottom for saving the session.
Let's fill out the form to begin our ingest. We recommend using similar values as the ones shown in the screen capture to make following the tutorial easier.
Make sure you select
Media Type and all the fields with a red
* are filled up. Then press
Move on to next step at the bottom of the webform to load the next step in line.
Since this is our first digital object we do not yet have a Digital Object Collection for which
My First Digital Object could be a member of. In other words, you can leave
Collection Membership blank and click
Next: Upload Files.
Why does this look different than Repository X?
We assume you come from a world where repositories define different Content types and the shape, the fields and values (Schema) are fixed and set by someone else or at least quite complicated to configure. This is where Archipelago differs and starts to propose its own style. You noticed that there is a single Content Type named
Digital Object and you have here a single Web Form. So how does this allow you to have images, sequences, videos, audio, 3D images, etc?
There are many ways of answering that, Archipelago works under the idea of an (or many) Open Schema(s), and that notion permeates the whole environment. Practical answer and simplest way to explain based on this demo is:
Digital Objectis a generic container for any shape of metadata. Metadata is generated either via this Webform-based widget you're currently using, manually (power-user need only) or via APIs. Because of this, Metadata can take any shape to express your needs of Digital Objects and therefore we do not recommend making multiple Digital Object types. However, if you ever do need more Digital Object types, the option is available.
- The Strawberry field Field Widget allows you to attach any
Webform, built using the
Webform Moduleand Webforms can be setup in almost infinite ways. Any field, combo, or style can be used. Multi Step, single step - we made sure they always only touch/modify data they know how to touch, so even a single input element webform would ensure any previous metadata to persist even if not readable by itself (See the potential?). And Each Webform can be also quite smart!
- The Strawberry field Field Widget will take all your Webform input, process any uploaded files, generate a JSON representation, enrich and complement it with Archipelago specific data and save it for you inside the
We will come back to this later.
As the name of this step suggests; you will be adding all your Linked Data elements here. This step showcases some of the autocomplete Linked Data Webform elements we built for Archipelago. We truly believe in Wikidata as an open, honest, source of Linked Open Data and also one where you can contribute back. But we also have LoC autocompletes and Getty.
Again, enter all fields with a red
* and when you are finished, click
Move on to next step
When entering a location, place or address you will need to click on the
Search OpenStreet Maps button, which is what that big red arrow is pointing to in the screenshot below.
Now we will upload our
Choose Files to open your file selector window and choose which file you would like to ingest.
Once you've uploaded your file, you will see all the Exif data extracted from the image, like so...
Once you've mentally digested all of that data, let's go ahead and click
Wait! Why only the metadata? I'm ready for this Digital Object to be shared with the world!
Save Metadata we are simply persisting all the metadata in the current webform session. The actual ingest of the Object happens when you click
Save on the next and final step,
Alright, we've made it. We've added metadata, linked Data, uploaded our files and now... we're ready to save! Go ahead and change the status from Draft to Published and click
Once you hit save you should see the following green message and your first Archipelago Digital Object!
Congratulations on creating your first digital object! 🍓
