| − | 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 or hosting the results on your site, see the [http://google.com/coop/docs/cse/cref.html Linked CSE documentation] from Google.

| − | Another re-use scenario is the use 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 [http://cnx.org Connexions] are labeled with <code>connexions</code>. Using these labels you can promote the results from your site while still maintaining the web-scale breadth of Open Education Search.
| |

| − | Weight adjustment requires publishing a context file which provides the basic definition of your search engine. Within this definition you can define a relative weighting for a label:
| |
| − | | |
| − | <code><pre>
| |
| − | <Label name="connexions" mode="BOOST" weight="0.8"></Label>
| |
| − | </pre></code>

| |
| − | | |
| − | <code><pre>
| |
| − | <Include type="Annotations" href="http://oercloud.creativecommons.org/api/posts/coop?p=0"/>

Data Gathered
The DiscoverEd project is a scalable search of educational resources with a special emphasis on Open Educational Resources (OER). As such, it utilizes a web-wide index, promoting results which have been identified as OER. DiscoverEd.creativecommons.org is serving as an aggregation point for other organizations which have identified or produced OER.
Data are aggregated from several sources, including:
- RSS and Atom feeds (title, description and subject information)
- OAI-PMH repositories (OAI-DC metadata)
- Crawled pages (embedded RDFa)
You can read more details about our metadata specifications. The aggregated information, along with source annotations, is stored in a triple store. This information is available as a SPARQL endpoint.
