| Welcome to the Spoken tutorial on Taxonomy.  

| In this tutorial, we will learn about:

  Taxonomy and Adding a Taxonomy.  

| To record this tutorial, I am using:Ubuntu Linux Operating System Drupal 8 and Firefox Web browser. You can use any web browser as per your choice.  

| Now that we have all of our Content types and fields built, we need to add categorization. And, that’s where Taxonomy comes in.  

| Taxonomy is nothing else but Categories.  

| Going back to our IMDB example, recall that we had a Movie Genre field on the IMDB site.

| Well, here’s the way it works in Drupal’s taxonomy.  

| Movie genre would be a vocabulary and that’s the term for the main category.  

| And in that vocabulary, we have Terms.  

| So, on the screen, we have ACTION, ADVENTURE, COMEDY, DRAMA and ROMANCE.

| And then under COMEDY, we have ROMANTIC, ACTION, SLAPSTICK and SCREWBALL.  

| We can have unlimited nested categories or terms in a Drupal vocabulary or taxonomy.  

| One area that many sites fail on is -using the built-in tagging widget or the tag vocabulary to categorize their content.  

| While it is great to be able to add categories on the fly, it has some inherent problems.  

| So, "energy" – e n e r g y isn’t the same as e n r e g y and Drupal doesn’t know the difference.  

| So, suddenly we will have 2 categories and the content is no longer connected.  

| That’s why we always recommend a closed taxonomy, like the one on the screen.  

| For now understand that Taxonomy can be used in so many ways.  

| We’ve already seen how it creates lists of content. But we can also use taxonomy to filter and sort all kinds of Views, if we use it correctly.  

| Well, let’s dive into taxonomy now.  

| We will set up a taxonomy for our 'Events' Content type.

| Click on Structure, scroll down and click on Taxonomy.

| As you probably remember, we have been setting up tags all along.  

| But as I mentioned earlier, we want to have a closed taxonomy- something that we can control and not something that people can easily add terms to.  

| So, we will click on Add vocabulary. Let’s name this as "Event Topics".  

| In the Description, we will type - "this is where we track the topics for Drupal events".  

| Click Save. Now we can add terms to our vocabulary.Click on Add a term.  

| On the screen, you see a list of the terms that we are going to add –

  Introduction to Drupal, Site Building,  

| Module Development,

Theming and Performance.  

| Let’s add those – Introduction to Drupal and click Save.

| And, it brings us back to this Add screen again.  

| Now, I’ll type "Site Building" and click Save.

| "Module Development" and click Save. "Theming". I’m just pressing Enter and it automatically saves.  

| And then the last one is "Performance" and click Save.  

| We can add complex vocabulary here, but we’ll just keep this simple for now.  

| Clicking on Taxonomy here and listing the terms in the Event Topics.

| We now have Introduction, Module Development, Performance, Site Building and Theming.

| So, I’m going to move Module Development down, Site Building up.  

| And, I am going to put Theming after Site Building and then Performance at the very end.  

| Just click and drag these. Always remember to save your changes.   

| Otherwise Drupal won’t remember them after you leave the screen.  

| So, click Save. And there we have our terms in the order that we want.  

| We have added the taxonomy but our Content type doesn’t know about this yet.  

| So, let’s go and click on Structure, Content types.

| And let’s manage our Fields and the 'Events' Content type. Then click Add field.

| Selecting a field type in this case is a Reference to the Taxonomy term, in the vocabulary that we just created.  

| So, choose Taxonomy term and let’s name this Event Topics. Click Save and continue.  

| And now it’s going to ask us which Type of item to reference.  

| Since we have already chosen that, be careful here. We will change it to Unlimited because an event can have more than one topic.  

| Click Save field settings.

| And down here, we need to make sure that we choose the correct Reference type.  

| Let’s choose Event Topics. Here, this is going to allow us to create references entities if they don’t already exist.  

| This is called Inline entity reference. Basically it means, if there was a topic that wasn’t in our listing, then any user can add it on the fly. വുന്നതാണ്

| Click Save settings.  

| We need to set up our URL patterns and we usually do this before we add content.  

| This ensures that the content we add has the correct human-friendly URL.  

| In this tutorial, we have learnt about:Taxonomy and Adding a Taxonomy.
