How to write a info engine task to fetch the metadata of an attribute

HI ,

Please help me to write an info engine task that could fetch the metadata of an attribute on a subtype. I am new to info*engine architecture.

I am using Windchill 10.2 M020 for PDM and CEM module. I have a subtype of "Customer Experience" object. I have defined an attribute "SourceSystem" on this subtype.

I am trying to fetch the constriants, default values etc.. for this attribute.

Thanks
