Can I access metadata (InfoExtension) from my velocity templates

Hello all,

Being fairly new to Cayenne, this may be an obvious question. I would like to know how I can access the metadata stored on an attribute/relationship/entity in the datamap from within my velocity templates (I think in CayenneModeler, this is how the comment field is stored for a datamap item). I think this is the metadata stored via the newish InfoExtension facility.

I see that the DataChannelMetaData can be injected into a DataDomain (and I’m doing that at runtime in my server app), however I cannot see how to get to this metadata from an attribute or relationship or entity in the context of a velocity template. Is this possible? I would think it is since Modeler is able to read/write those comments, but I am having a hard time doing so in a template.

I did see that there is a hook to provide my own tool into the cgen tool. Would this be a potential path to look into if the metadata is not accessible directly in the templates as is? If so, any pointers on where to start?

Thanks for any advice.
