Data Transformation and Mapping

[mgubaidullin]

We are brainstorming/prototyping the most demanded requirement for Karavan: Data Transformation Mapping.
All aspects: Runtime, Formats, UI/UX, etc.

It would be nice to have operations similar to the data mapper mediator from WSO2.

I Like the green bullet to show there is a connection like in this video: https://www.lobster-world.com/wp-content/uploads/2023/05/Mapping-Engine.mp4

Getting configuration properties from an externally located file and mapping those configurations to the Kamelets or integration components to external upstream/downstream systems.

Even though, this is already supported by referencing the properties present in application.properties within the local workspace for a Karavan project, it would be cool if the Data Transformation/Mapping capability could enable this for configuration files that could be located remotely.

@mgubaidullin a question: are you going to support AtlasMap (I remember some hypothetical plans from your roadmap https://camel.apache.org/blog/2022/10/camel-karavan-roadmap/) , or not? The project looks almost dead, unfortunately. It's quite promising, IMO - but looks abandoned.

Btw, have you checked some alternatives for AtlasMap? Quoting you from the link above:

We are analyzing existing open-source data mapping solutions like AtlasMap that might be embedded into Karavan Designer.

Have you found something in particular? If so, do you mind sharing your findings? I'm looking for the such solution (ideally backed by a Camel component), but the only mapper with the visual representation I could find was only AtlasMap. Or maybe something without UI, but with the same somewhat universal mapping (XML/JSON -> JSON/XML).

Thanks in advance!

Hey. I had archived the AtlasMap in karavan.
It can transfer xml/json/java -> to xml/jason/java.

[guoxunbo]

Because altasMap had many error/warning with use.so I create entityMap point to expands altasmap.

The Mapping view like this. It can use java/json/xml to mapping them later.

I couldn't find entityMap in the component or Kamelet. Are you using a custom component? Could you share some resources on how I can create one as well?

[kondetiramanakumar]

@guoxunbo I am also not able to find the entitymap component in the kamelets. please share the resources on how to create the entity map???

[guoxunbo]

Here can edit the mapping transformation. such as leftpad, rightpad...

Hello, Is this feature ready ? When can we expect this in Karavan to use ?

[mgubaidullin]

This feature is not yet implemented. No due date is planned yet

[rapetum228]

Looks very interesting. We are waiting 😊

[kondetiramanakumar]

Hi all , As a part of my requirement we required the atlasmap similar feature in the karavan for mapping and transforming the fields. any suggestions on my requirement???

[samar-elsayed]

this looks very promising, I hope you can pick it up and release it
it will be handy for my team
