Because writing metadata

should be fun!

Well, maybe that’s a bit much to ask…but shouldn’t writing high quality metadata be easy? So you don’t know the difference between ISO 19139 and FGDC CSDGM? No problem! The mdEditor requires no special expertise or knowledge. If you can use a web browser, you can use the mdEditor.

The main goal of the editor is to promote the creation and use of metadata by lowering the level of technical expertise required to produce archival quality metadata.

The User Manual is intended to be a companion to users as they author metadata with the assistance of mdEditor. This manual will discuss how to use mdEditor. Topics generally covered include workflow and how to perform specific tasks within mdEditor.


1. You’ll need a recent version of a modern web browser.

Any of these should work:

Note: Internet Explorer <=11 is not supported by default. If you need IE support let us know.

2. Point your browser at https://go.mdeditor.org

3. Start writing metadata!


Frequently Asked Questions

  1. What metadata formats are supported?
  2. Is my metadata saved on the website?
  3. Where is my metadata saved?

  1. What metadata formats are supported?

    The native format used by the mdEditor is mdJSON. However, the mdEditor can export to other metadata formats using the mdTranslator. How mdTranslator works

  2. Is my metadata saved on the website?

    No, actually mdEditor runs inside your browser (it initially loads from our website). Your metadata is not kept on our website, and the mdEditor will not transmit your metadata without you telling it to (e.g. translating or publishing).

  3. Where is my metadata saved?

    By default, the edited metadata is saved within the browser itself, in the localStorage cache, which allows the data to persist between page loads. This will retain the metadata until the cache is cleared. You can also easily export the metadata to your local disk in mdJSON format at any time, or load an mdJSON file from disk.
