Overview

This proposal is to add the option to harvest service and observation offering metadata from the GetCapabilities document returned from an SOS server to the OGC WxS Harvester.

This proposal also adds the ability to specify schema specific mappings for OGC WxS harvesters including plugin profiles (this harvester was originally designed for the iso19139.mcp profile).

Motivations

The marine community in Australia is increasingly looking to make use of OGC Sensor Observation services to publish marine data with many services already being made available. The addition of an SOS harvesting option to geonetwork will facilitate the discovery and access of these services via the Australian Oceans Data Network (AODN) by making it a simple process to publish service details to the AODN's service/dataset catalog (the ANZ-MEST/geonetwork).

Proposal

This proposal adds to the existing OGC WxS harvester. For more details on what this harvester currently does and how it works refer to the existing documentation on this harvester or the original proposal to add this harvester to geonetwork.

Schema Specific Harvesting

This proposal adds the ability to define schema specific harvesting of OGC WxS GetCapabilities metadata. In particular, the stylesheets to be used to harvest metadata for a particular OGC service type for a particular target output schema are placed in the convert/OGCWxSGetCapabilitiesto19119 directory for the schema or schema plugin. e.g.

For a schema plugin:

  schemaPlugins/iso19139.mcp-1.4/convert/OGCWxSGetCapabilitiesto19119/
    OGCSOSGetCapabilitiesLayer-to-19139.xsl
    OGCSOSGetCapabilities-to-ISO19119_ISO19139.xsl

For one of the core geonetwork schemas:

  xml/schemas/convert/OGCWxSGetCapabilitiesto19119/
    OGCCSWGetCapabilities-to-ISO19119_ISO19139.xsl
    OGCSOSGetCapabilitiesLayer-to-19139.xsl
    OGCSOSGetCapabilities-to-ISO19119_ISO19139.xsl
    OGCWCSGetCapabilitiesLayer-to-19139.xsl
    OGCWCSGetCapabilities-to-ISO19119_ISO19139.xsl
    OGCWFSGetCapabilitiesLayer-to-19139.xsl
    OGCWFSGetCapabilities-to-ISO19119_ISO19139.xsl
    OGCWMSGetCapabilitiesLayer-to-19139.xsl
    OGCWMSGetCapabilities-to-ISO19119_ISO19139.xsl
    OGCWPSGetCapabilities-to-ISO19119_ISO19139.xsl

When a particular OGC Service type is selected in the OGC WxS harvester, all registered schema directories will be scanned to determine which schemas support harvesting metadata for that particular type and the user will be able to select the target schema to use in the harvester:
