Open Education Search is a project of ccLearn. You can find more information on the project at http://learn.creativecommons.org/projects/oesearch/.

This page documents ways in which developers may use the data gathered by the project for other purposes, including integration and customization.

Data Gathered

The Open Education Search (OES) project is a web-scale search of Open Educational Resources (OER). As such, it utilizes a web-wide index, promoting results which have been identified as OER. ccLearn is serving as an aggregation point for other organizations which have identified or produced OER. At this time we gather:

  • URLs or URL patterns
  • Subject annotations, sometimes called labels

We are not currently attempting to aggregate rich metadata sets.

The data gathered is currently available in a format suitable for use in a Google Custom Search Engine; ccLearn is committed to making it available in a "raw" format for further reuse.

Integrating Open Education Search

Any site may include Open Education Search on their website by pointing to our CSE context definition. For example, the following block of HTML will produce a search box with the same semantics as Open Education Search. For more information on customizing the results format, etc, see the Linked CSE documentation from Google.


<form id="cref" action="http://google.com/cse">
  <input type="hidden" name="cref"
    value="http://oercloud.creativecommons.org/api/posts_context"
    />
  <input type="text" name="q" size="40" />
  <input type="submit" name="sa" value="Search" />
</form>
<script type="text/javascript"
   src="http://google.com/coop/cse/brand?form=cref"></script>

Customizing OE Search

Another re-use scenario is the reuse of the dataset, with adjustments made to result weighting. We use labels for subject annotations, as well as annotating the source of the URL. For example, URLs received from Connexions are labeled with connexions.


<Label name="ocw" mode="BOOST" weight="0.8"></Label>
