The above article covers vocabulary creation, but does not address how to update existing vocabularies. This article explains how to update existing vocabularies.
Creating a Vocabulary# As an example, we will create the following vocabulary.

Accessing the above URL will download the following TTL file. Here, we have added a custom property called myprefix:mySpecificProperty.

Select the modified file as follows.
On the next screen, you can confirm what changes will be made.
After approval, you can update the content of the registered vocabulary as follows.
Summary# Updating vocabularies requires going through an RDF file, which involves a somewhat complex procedure as described above. I hope you find this helpful.
