About the Open Source METS Metadata Editor
One of the newest of the continual upgrades to the UF Digital Collections is online metadata editing. To make that fully operational our programmer, Mark Sullivan, revised the current standalone METS Metadata Editor application to ensure it remained in parallel. In doing so, Mark noticed that he could quickly adapt our METS Metadata Editor to serve the needs of all of the State University Libraries in Florida. Mark made those updates and the METS Metadata Editor is now available for download here.
The METS Metadata Editor is an Open Source .NET application and features:

• METS Object and METS Reader
  • Good object-oriented example, plug and play for .NET users
  • METS mappings
  • MARC ? METS/MODS ? MARC
  • METS/MODS ? Greenstone file
  • METS/MODS ? Dublin Core (could easily include Dublin core ? METS/MODS)

The METS Metadata Editor is available as an Open Source download for the Windows application from here.
In the near future, the code for the METS Metadata Editor Web application will also be available for download. The code for the  METS Metadata Editor Web application is already powering online metadata editing for the UF Digital Collections, but it’s still new and we’re gathering and incorporating user feedback to further optimize the interface right now. Once released, the METS Editor Web Application will allow users to enter and edit METS files. It probably will not include a logon system, but will instead save into a folder by IP or session number. Then, users will be able to create an item, view it, edit it, download METS, MARC, etc. A bulk importer from MARC and spreadsheets will also be available as a bundled part of the standalone and web application. The Digital Library Center already uses the importer as part of our production toolkit.
As we release more Open Source tools, please note that we’re revising our documentation but it may have different names for some of the same tools until we finish editing. The different names are all for our production toolkit, which is sometimes referred to as the DLC Toolkit, the UFDC Toolkit, the Digital Library of the Caribbean or dLOC Toolkit, and the SobekCM Toolkit. The SobekCM Toolkit has many names because the coding is brilliantly architected and modular, with the same code powering multiple tools and customized tool sets, multiple production scenarios, and multiple versions of the same applications customized for the different user groups.  Translating among the names our users know for their tools and the system components causes confusion, so we’re now referring to the collections by their names and the system-parts by the name SobekCM. The CM is for collection and content management, and Sobek is the name of an Egyptian crocodile god (because even crocodiles are Gators in Gainesville).
To help aid with any possible confusion on terminology, we have definition pages for general terms and for specific metadata fields. We’re still working on the pages for the metadata fields, because they provide a lot more than just a definition.
