CCIN Interoperable Web Services

1. OAI – PMH (Open Archives Initiative Protocol for Metadata Harvesting)

Our OAI–PMH service currently offers the PDC Metadata XML files in two formats: the FGDC-STD-001-1998 standard and the North American Profile (NAP) of ISO-19115.

a. OAI-PMH link for harvesting CCIN’s metadata (currently 2540 records) into a remote server:

The above link will not work in a browser. It must be accessed via an interoperable OAI-PMH tool such as jOAI (further information on OAI-PMH software can be found at or by other harvesting software such as GeoNetwork.

2. GeoServer

CCIN utilizes GeoServer for interoperability purposes, to dynamically share geospatial data. All spatial data are shared using open standards from the Open Geospatial Consortium (OGC). The WMS and WFS links below are used for Map Services and are not viewable in a web browser. a. Selected geospatial datasets from the Polar Data Catalogue are converted into shapefiles (from their original formats) and made available via WFS in GeoServer: WFS link (this can be opened in GIS software to see the layers that are available):

KML, GML, and Metadata* (*visible in browser) links for a sample dataset:

b. The PDC Metadata collection is also being made available via WMS:

3. GeoNetwork

As a pilot project, GeoNetwork is being configured to serve the PDC Metadata collection as a Catalogue Service for the Web (CSW), to provide additional flexibility and options for metadata interoperability. Warning: This service is not official yet, and the metadata files are not up-to-date. GeoNetwork test link:
