Metadata files are sent to NAL using a File Transfer Protocol (FTP).
FTP is a standard Internet protocol for transmitting files between computers on the Internet. Like the Hypertext Transfer Protocol (HTTP), which transfers displayable Web pages and related files, and the Simple Mail Transfer Protocol (SMTP), which transfers e-mail, FTP is an application protocol that uses the Internet's TCP/IP protocols. FTP is commonly used to transfer files from your computer to other servers.
Publishers may only send files via FTP using a static IP address. When a device is assigned a static IP address, it does not change. The device always has the same IP address. Most devices use dynamic IP addresses, which are assigned by the network when they connect. If you cannot provide a static IP address please contact NAL for further assistance:
NAL is able to recieve metadata as individual XML files or a set of XML files in a zip archive. Subdirectories or folders should not be created on our FTP server.
When the publisher’s metadata sample has been accepted, the FTP account creation process is as follows:
1. FTP account is created by NAL staff.
2. FTP login ID and the NAL IP address are sent to the publisher in an email. The login ID consists of lowercase letters.
3. A second email containing only the FTP account password is then immediately sent to the publisher. The message will contain the same subject line.
4. Files can be transferred using open-source FTP software such as WinSCP which is available for download at: http://winscp.net/eng/download.php
5. In the URL box type in: ftp.nal.usda.gov. Then supply your assigned user ID and password.
6. NAL IP address is: 188.8.131.52
7. If you are unable to send files via FTP, they can be emailed to: AGRICOLAPublishers@ars.usda.gov
