2.5 Layer metadata
|
For a 2 star accredited service, ALL OneGeology layers must conform to these naming protocols. |
The OneGeology portal is layer-level based, rather than service-level based. It is the layer metadata that is shown to the users in the portal itself. It is therefore important to add as much metadata as possible to each of the layers. Even if most of your metadata is the same for your layers and for your service, you should replicate that data in the layer metadata.
It is worth starting this section by noting the differences between titles and names (applicable to services and layers) in the GetCapabilities response. A name is a short string (containing no spaces) used by computers to identify the data, whereas a title is a human readable phrase.
To simplify the rules for the user and to avoid name duplication in the registry, for the OneGeology Portal WMS profile, layer titles and layer names are used to encapsulate exactly the same information, the only difference being the style described above, and that we may shorten or abbreviate the information in the name. In the name we take any spaces that exist in the title and replace with the underscore character (_).
The metadata information required by the layer name and the layer title are (in order):
[Geographical extent] of the data in the layer, then [Data owner organization] (not service provider), then [Language code] (if non-default as per service naming conventions), then [Scale], then [Theme] (we decided not to call this FeatureType because that is too closely linked with GeoSciML).
