About Catalog Toolkit
Catalog Toolkit is a fast and easy way of setting up the UI for your catalog to meet your business needs -- that is adding custom fields and sections to the UI, adding custom resources, creating subtypes for glossary terms.
Your installation is setup with 4 organizations:
Catalog Configuration organization: Where you will create the metadata profile.
Catalog Sources organization: This is where you upload your data via collectors, connection manager etc.
Catalog Sandbox organization: This is a preview or QA environment where you can check if you did the setup correctly.
Catalog Main organization: This is the production organization that the end users see.
The data.world team will help set up the initial metadata profile for you in the Configuration organization. This documentation will walk you through the process of maintaining the configurations.
