What is the NBII<br />
A broad, collaborative program designed<br />
to provide access to data and information<br />
on biological resources

What is a Data Set<br />
• A collection of data that is raw or<br />
statistically analyzed<br />
– Generally data sets are defined as:<br />
• Spatial – a collection of logically related features<br />
arranged in a prescribed manner such as GIS map<br />
layers, water features, etc<br />
• Tabular – a file, spreadsheet, data in a table<br />
– Elements in a data set can include:<br />
• Values, measures, points, coordinates, conditions,<br />
qualities, frequencies, or attributes that are a result<br />
of an observational study
Information Management: Describing the Dataset<br />
Federal Geographic Data Committee (FGDC) Content Standard for<br />
Geospatial <strong>Metadata</strong>
The <strong>Metadata</strong> Process:<br />
(did someone say metadata!)
To create FGDC compliant metadata records:<br />

standard
Enter information using an electronic tool
When creating a record, address the 7 Sections<br />
of the Standard:<br />
1. Identification Information<br />
2. Data Quality Information<br />
3. Spatial Data Information<br />
4. Spatial Reference Information<br />
5. Entity and Attribute Information<br />
6. Data Distribution Information<br />
7. <strong>Metadata</strong> Reference<br />

Become a <strong>Clearinghouse</strong> partner:<br />
• Upload records to a<br />
web-accessible folder<br />
• Records should be<br />
in .xml format<br />
• Inform NBII of folder<br />
location (one-time only)<br />
Note: Contact Viv Hutchison<br />
(vhutchison@usgs.gov) for<br />
assistance in this process<br />
• NBII will harvest<br />
records weekly

Nuts and Bolts of the NBII <strong>Clearinghouse</strong><br />
The NBII <strong>Clearinghouse</strong> is powered by Mercury:<br />
- metadata harvesting, search and retrieval tool<br />
- single portal to information contained in disparate data<br />
management systems<br />
- originally developed for NASA, with continuing development<br />
funded by NASA, USGS, and DOE for a consortium of projects<br />
Mercury supports various metadata<br />
standards:<br />
- XML, Z39.50, FGDC, Dublin-Core,<br />
Darwin-Core, EML, and ISO-19115<br />
- based on open source and Service<br />
Oriented Architecture (Solr and Lucene)<br />
to provide multiples search services
Preparing for ISO…<br />
The international community,<br />
through the International<br />
Organization for<br />
Standardization (ISO) has<br />
designed a standard for<br />
geospatial metadata.<br />
The NBII is prepared to accept ISO metadata<br />
records once the North American Profile is<br />
approved.<br />
The “North American Profile” (NAP) will<br />
replace the current Version 2 FGDC<br />
Standard, and essentially become Version 3
Preparing for ISO…<br />
Tools and crosswalks<br />
are being prepared for<br />
the transition to ISO<br />
by the FGDC.<br />
The NBII<br />
<strong>Clearinghouse</strong> will add<br />
a “View ISO <strong>Metadata</strong>”<br />
button to the record<br />
results page<br />
The NBII is moving toward greater participation in the<br />
<strong>Clearinghouse</strong> from the international community.<br />
Efforts being made in South America, Central America,<br />
Asia and Europe
