In the past I have been entering keywords in "Edit Layer" section of GeoServer. These keywords have shown up on a per layer basis in the "KeywordList" section of a WMS GetCapabilities response, which has allowed me to create a layer tree for my map application. I have recently moved over to using WMTS GetCapabilities requests, however these responses do not show the "KeywordList" section. Is there a way to get this metadata to show up in WMTS GetCapabilities responses?
I have seen there is a "INSPIRE extension" for GeoServer which says it can expand WMTS metadata requests, however after installing it successfully, I have been unable to get the "KeywordList" section to show up. Does anyone have any suggestions?
