Hello,
Currently we have 3 component frameworks in Talend Studio. The Talend Component Kit (TCOMPv1 / TCK) that you started to develop on, TCOMPv0 which is deprecated, and the JavaJet based components that you're asking of.
DBRow / tMap:
These are standard DI components hence they are under the tdi-studio project:
https://github.com/Talend/tdi-studio-se/tree/master/main/plugins/org.talend.designer.components.loca...
(You can find the same folder in your studio. plugins/*localprovider* )
There are multiple localproviders depending on the product / license.
Some bigdata components are also available for Data Integration jobs:
https://github.com/Talend/tbd-studio-se/tree/master/main/plugins/org.talend.designer.components.bigd...
As for the TCOMPv0 components the open source ones are here:
https://github.com/Talend/components/tree/master/components
And the TCOMPv1 / Component Kit based ones are here:
https://github.com/Talend/connectors-se
For this we have the starter-toolkit that should help designing the UI interface and generate the skeleton: https://starter-toolkit.talend.io
I hope this helps.
