Im using WSO2 Governance Registry 5.2.0.
When I create a new artifact type, it containt a lot of new fields (You create and define this XML in the CARBON ADMIN CONSOLE).
As far as I understand your in the development phase of the project that you have to create registry extensions(RXTs) and showing up the data in G-Reg Store. As far as I know there is no easy dynamic way that you can do this, either you have to extend the default hbs files. Like you have done using Malintha's blog. This is okay if there is a minor change to be done, However this is not the recommended way because if there is a migration to do such as moving to all new WSO2 G-Reg 5.3.0 you might face lot of trouble if you updated the out of the box files in G-Reg 5.2.0, Therefore I suggest you to write asset extensions(GREG_HOME/repository/deployment/server/jaggeryapps/store/extensions/assets
) for each and every rxt that you are going to introduce. There is plenty of blog posts that can help you.
Please find the below list of blog posts(I will update the list if I found any).

Overriding default "look and feel" of GREG - 5.3.0
Note:
There is no much difference between 5.1.0 and 5.2.0.(5.2.0 is more stable)
You can start(learn) creating a new extension by simply extending restservice.rxt and the relevant asset extension(GREG_HOME/repository/deployment/server/jaggeryapps/store/extensions/assets/restservice), I prefer you to use this blog post and start from there.
If there is a lot of development to be done I prefer you to seek help from WSO2 experts from they're official portal, if not you can always stick to stackoverflow.
