Get keyword metadata information from layer using REST

[uniomni]

Each layer in GeoServer has a list of keywords that can be manually entered and read through the GeoServer web interface.
The Risk in a Box Server will be using these to signify the type of each data layer - e.g. keyword type:exposure would indicate that the layer is an exposure data layer. Other types could be type:hazard, type:boundaries, type:impact, ....

How can these fields be obtained programmatically presumably using REST?
