GeoSciML meeting – Orléans – France 25 & 26 Feb 2008 > 16 Use Case 1: How to access and use SLDs > SLD from a WMS the client knows the WMS URL from the catalogue and the layer name the client requests the WMS capabilities to find SLD available for this layer  The Catalogue should be able to provide the style name and title for the selected layer but this information is not yet stored into the GeoNetwork catalogue (no ISO19115 element for this)  Update the GeoNetwork catalogue with extension ? > “generic” SLD – standalone – stored into the catalogue Search for “SLD” Resource and download the SLD file or use the CSW service – Must have a keyword “SLD” to search with CSW Issues with the use of the “generic” SLD – Must contain the layer name – SLD filter and urn must be mapped to our own servers

GeoSciML meeting – Orléans – France 25 & 26 Feb 2008 > 30 Use case 2 & Use case 3 : WFS query and download To do: To insert into the GeoSciML Client the components tested To add the “draw box” function To highlight selected features on the map? To update our WFS-X to process queries on boreholes (UC3d – attributes “length >x and lithologie is y”) To use WFS profiles? Issues: How to link Layer displayed on the map and WFS to query? – The user knows this link: he selects the WFS in a list (provided by the Catalogue) – This link is defined into the WMS Capabilities for each layer? ( - Eric proposal?) – This link is registered into the Catalogue?

GeoSciML meeting – Orléans – France 25 & 26 Feb 2008 > 31 Use case 4 : Data transport between products (GeoModeller, GSI3D, GDM) Already available: GDM has a GeoSciML parser (v1) Examples for boreholes according to GeoSciML v2 A new 3D viewer (demo) To do: To update the GDM parser to process GeoSciML v2 To take into account “urn” (to use the Gsml Resources service) To process the two possible ways to describe boreholes with GeoSciML To write the Data Product Specification For GDM

GeoSciML meeting – Orléans – France 25 & 26 Feb 2008 > 32 Use case 5: Next steps to satisfy other use cases requirements? To do: To improve the GeoNetwork Catalogue: – to modify the service metadata ID for an easier use – to store style name and title of each layer – to test it for WFS and WCS – to improve our experience of using the CSW interface – to manage Service profiles – query models? To improve the Gsml Resources Service – to process relationships between concepts – to check if the formats of the results meet all requirements Other points: To define the amount of metadata the Catalogue should store: – only to discover the services and datasets, then the client works with the capabilities – or to store much more information, to help the client Need to have “final” vocabularies (at least for lithology and age) What about using an open source tool (available in the “ontology” community) to manage the vocabularies content, and transform it into a GeoSciML format
