| 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.

 

| Let us open our website which we created earlier.  

| 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'''.  

| Now, here’s one thing that is really important.  

| 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.  

| What happens if someone types a typo?  

| 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'''.  

| It’s easy to set up and we are going to do that later on, in this series.  

| 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'''.

| And, they’re in alphabetical order.  

| But, I want to arrange them in the order of difficulty.  

| 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.  

| We don’t want anyone to do that. So, we will leave that unchecked.  

| Click '''Save settings'''.  

| There is one more step before we add content.  

| 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'''.  

| We’ll do that later on, in this series. With this, we come to the end of this tutorial.  

| Let us summarize.  

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