Using the Geoportal REST API

The REST API in the Geoportal

The Geoportal REST API allows each metadata record in the geoportal catalog to be assigned a unique web-accessible URL. The geoportal's catalog can also be queried through URLs using REST syntax. Accessing individual metadata documents through their REST URLs, or groups of documents that match specific search criteria through a REST-formatted search URL, provides powerful functionality for searching, viewing, and sharing records. For example, you can send the URL to a metadata document or a search to colleagues, and they can access that resource without having to go to the geoportal and conduct their own search. Integrating the URLs into other webpages, or your organization's Content Management System, provides users with quick links to resources again without having to do their own search. Additionally, the REST API allows for easy integration with external applications, as described below.

To see the REST URL for an individual metadata record, click on the 'Details' link for the record in a list of search results, and scroll to the bottom of the Details page. The URL will be formatted similar to the following, with a unique GUID replacing the one shown here in italics.

 /geoportal/rest/document?f=html&id=%7BF6B6CCA6-9013-4018-9FFE-5F8163E27FBD%7D

To see the REST-formatted results for a specific search, scroll to the bottom of the geoportal's search results page after carrying out a search with your criteria of interest. You will see links to viewing the search in the GEORSS, ATOM, HTML, FRAGMENT, KML, or JSON REST format. Each REST format is described in the table below, with an example of how that format can be used in an external application.
