Software and ontology developers are welcome to participate, follow the project, and download code.


The eagle-i software suite consists of 6 web applications:

  • eagle-i Central Search and iPS Cell Search for resource discovery and exploration
  • Institutional search for a single repository search UI
  • Ontology Browser for viewing the eagle-i ontology without any additional applications
  • SWEET (Semantic Web Entry & Editing Tool) for manually entering and managing data in an eagle-i repository
  • RDF repository for storing resource and provenance metadata as RDF triples
  • SPARQLer a SPARQL query entry point and workbench to query an eagle-i repository

Those web applications are serviced by 2 toolkits:

  • ETL (extract, transform, and load) toolkit for batch entry of information to an eagle-i repository in an ontology-compliant manner
  • Data management toolkit for bulk data maintenance and migration

Our software development platform offers comprehensive integrated tools for developers, including: JIRA bug tracking, Confluence Wiki, Bamboo continuous builds, Nexus download repository, Subversion source control, project mailing lists, and other build tools for code coverage and repository monitoring. The BSD-3 open source license allows the eagle-i software to be freely adopted, extended, and modified by third parties — without restriction as to the affiliation of the developer, or as to the ways in which the software can be shared and repurposed.

For details and documentation, open-source community information, and training materials, see the open source project site. If you have an existing application or an idea for a new one that could leverage eagle-i data, please contact us.


eagle-i Linked Open Data is available for consumption by any third party without restriction. The data in eagle-i is contributed by Network member institutions and can be freely accessed using our search tools. The data can also be exported in three additional ways:

You can also add the eagle-i search bar to your own website following these steps:

1. Add this to the <head> section of your page:

<link href="" rel="stylesheet" />
<script type="text/javascript" language="javascript" src="">
    <!-- this initialization is optional; by default the search bar will point to production search -->
    function initSearchBar() {

2. Add this to the area of your page where you want to embed the search bar:

<div id="searchPanel"> &#160;<!-- This space must not be collapsed --></div>

3. To modify the style of your search bar, add the following css styles to your page or css file:

#searchPanel        <div> that wraps whole search bar
.searchLabel        label to left of search bar
.searchBoxHeader    search box
.submitButton       submit button


The eagle-i Research Resource Ontology (ERO) models biomedical research resources. It was developed alongside the eagle-i software and drives the functionality of the data entry and search applications. The ontology includes classes and properties created de novo within the ERO namespace, but also borrows extensively from and harmonizes with existing ontologies, largely from the OBO Foundry suite. The purpose of this approach is to maximize the ability of the eagle-i to share data with external applications.

The eagle-i ontology has now been fully integrated into the VIVO-ISF, which merges and expands upon the eagle-i and VIVO ontologies to represent not only resources but researchers and clinical activities. The eagle-i modules of the VIVO-ISF can be explored using the Ontology Browser application.
