The I3N Cataloguer was distributed free of charge by I3N Project Management to any participant who requests it. This tool provides a simple way to create data descriptions—called metadata—and to share these with others. The Cataloguer  presents forms on which information about databases is entered to create records, but it also transforms the records into XML-tagged text files that can be accessed by others if the files are posted on a Web server. Utilities to harvest, query, and display the information from all web servers are being developed. Read more about the I3N Cataloguer Concept, installation instructions, or visit the Developer's page for more information.

NOTE: Participants are strongly encouraged to use the I3N Database on Invasive Alien Species instead of the I3N Cataloguer. But if you still want to obtain a copy of the last version of the I3N Cataloguer (version 2.3), please email Andrea Grosse (agrosse@usgs.gov).
