The GeoSciML Portrayal schema standardizes the interaction (request/response formats) with layer-based map services. It is best thought of as a view of GeoSciML and O&M data that denormalizes the data and concatenates complex property values into single, human-readable, labels and returns single, representative, values from controlled vocabularies for properties multi-valued properties that can be used when generating thematic maps, or portrayals, of the data. It is separate to, but harmonized with, GeoSciML and O&M and conforms to the level 0 of the Simple Features Profile for GML (link). Labels, will be 'free-text' fields that will be, in robust services, well-structured summaries of complex GeoSciML data, while the representative thematic properties will be URIs of concepts in a controlled vocabulary (for example CGI Simple Lithology). There will also be links, via identifier URIs, providing hooks to full GeoSciML or O&M representations of a the geologic feature in question. Simplified view of a GeoSciML Borehole.
