[mapserver-users] Layer Metadata Questions

[Seth G]

Hi all,

I've been looking at using the Layer Metadata as described at https://mapserver.org/ogc/layer_metadata.html

"MapServer’s layer API supports the ISO 19115:2003 geospatial standard" - although looking at https://www.iso.org/standard/26020.html this has now been withdrawn and replaced with ISO 19115-1:2014 - https://www.iso.org/standard/53798.html
I presume there is not much difference between these 2 schemas? There is a ~180 EUR charge to get a copy of the PDF. 
The source code has a comment "Generate an ISO 19139:2007 representation of layer metadata " [1] - so maybe the docs need an update?

The second question regards the mapping of the LAYER METADATA block to the ISO output. There is a good test and expected output at [2] and [3]. 
Looking at the code it appears the "contact" metadata can only be retrieved at the MAP rather than LAYER level [2]. 
Is this something that should be available at LAYER level also, perhaps using "wms_attribution_title"?

Any comments appreciated,

Seth
