Accessing the Data.gov catalog through an open interface

In its first year, Data.gov has grown from 47 datasets to over 270,000 datasets. These datasets aren’t actually hosted at Data.gov. The government agencies making these datasets available, host the files (or web services), and share them with the community through data.gov. But how did these datasets become discoverable at Data.gov?

Actually, the datasets are registered with Geodata.gov, a national catalog of geospatial resources that has been around for some 7 years and that “serves as a public gateway for improving access to geospatial information and data under the Geospatial One-Stop E-Government initiative”.

Geodata.gov provides access to almost 400,000 geospatial resources from over 300 partner collections from federal, state, and local government, as well as academia and commercial providers. Rather than having to sift through as many web sites, users can go to Geodata.gov and perform searches there. Creators of the geospatial resources can register this content with Geodata.gov if they choose to do so.

SDI for Everyone

The topic of verbose metadata versus youtube-style metadata (a title and a video) in the context of Spatial Data Infrastructures is not new. Even publishers of geospatial content struggle with the verbose metadata standards that have been created over the years. Those metadata standards were not written with data discovery in mind. They resulted from the need for analysists to fully understand the data they were about to use to ensure it fit their purpose.

With the advent of the content sharing sites like Youtube or Flickr content sharing no longer was limited to the scientific/professional
