Validation rules in field

[David Orbelian]

Hi there.

My name is David and I am an ASP.NET developer. I am interested in using Siren for a little framework over AspNetCore I am currently developing. My target is to develop some tools for rapid developing a RESTful APIs. Ideal will be only creating models, marking them by special attributes and configuring the framework. 

I find Siren a good format for that purpose, but I also think there are some missing features which will make it more comprehensive. One of such things is to pass front-end validation rules within a field for an action. What do you think about it?

Best regards, David.
