Catalog Service

Geoportal Extension Catalog Service

If the Geoportal extension was a car, the Geoportal extension Catalog Service would be its engine, controlling other components, managing transactions, and providing the central interface for the discovery, publishing, and validation of metadata. Starting at version 9.3, the Geoportal included an implementation of the Open Geospatial Consortium (OGC) Catalog Service for the Web (CS-W) 2.0.2 interface specification. The link to this service will typically follow the format below: 

http://serverName:port/geoportal/csw?Request=GetCapabilities&Service=CSW&Version=2.0.2
where The Geoportal extension CS-W service makes possible support for arbitrary metadata schemas without complicating the search component of the Geoportal. When a metadata document is published to the Geoportal, the original metadata is retained unchanged and is used when editing the metadata in the online form or when displaying the full metadata as part of search results. At the same time, the Geoportal is able to extract searchable elements into a uniform structure, standardize domain values across metadata standards, determine the topic category codes or content types of the metadata document, select key content for connecting to online resources, and assign a unique identifier to the record. The capabilities of the Geoportal extension CS-W implementation will be described and sample requests and responses included in the sections below. See Geoportal extension WSDL for information about the web service definition files.

Details of the CS-W Interface

  1. SUPPORTED OPERATIONS: The Geoportal extension CS-W implementation supports the mandatory CS-W requests as well as the optional GetRecordsById and Transaction. The Transaction requests publish or update entire documents only. The Transaction delete request is based on file identifier alone. Geoportal publisher permissions for executing Transaction requests must be included in the HTTP header in the client application that submits the CS-W request. The client application's header and credentials must follow HTTP Authorization standards. The GetDomain and Harvest operations are not supported at this time.
    NoteNote:

    In the table below, the Obligation column indicates if the operation is mandatory or optional. Mandatory operations are required for the service to be minimally compliant with this CS-W specification. Optional operations are not required by the CS-W specification.

  3. CORE QUERYABLES: The Geoportal extension CS-W implementation supports CS-W core queryable properties, the ones defined in the CSW ISO Application Profile and additional queryables (applicable to ISO metadata only). The Geoportal extension information model is backed by XML documents and a spatial database. Its XML documents contain FGDC, ISO 19139, Dublin Core, or other XML elements and attributes. Below is a table, mapping OGC Catalog Core Queryables to items in the Geoportal extension information model. The remaining queryable properties relying on ISO 19115 and ISO 19119 metadata are faithfully following the names and mappings defined in OpenGIS® Catalogue Services Specification 2.0.2 - ISO Metadata Application Profile and Technical Guidance to implement INSPIRE Discovery Services Technical Guidance Version 2.12 .

    • The geometry operands supported for spatial queries are:
      1. gml:Envelope

  7. RETURNABLES:

    For the csw:Record output schema, the records returned contain a selection of the core returnables, of which the subset is dependent on the element set. When request=GetRecordById, outputSchema=original, and ElementSetName=full, the Geoportal extension CS-W interface returns the original metadata document as it was published to the Geoportal. For the gmd:MD_Metadata output schema, the records returned contain a selection of ISO metadata elements, of which the subset is dependent on the element set as defined in the OGC CSW ISO Application Profile.
