Hello MODS implementers,

The MODS/MADS Editorial Committee is in the final stages of planning for version 3.4 (very soon now, really!) and one of the outstanding issues before us is whether or not to do more with the <extension> element. We've heard a number of times along the way that it would be helpful to have <extension> not just at the top level but also inside specific MODS elements. We'd like to hear from you about your current practice and needs for <extension> to better plan for how and if this should be implemented.

1) What type of data are you currently putting in the top-level <extension> element?

2) Do you have specific cases in which it would be helpful to you to have <extension> inside a specific MODS element rather than at the top level to convey additional semantics?

3) Have you made changes to the MODS schema locally to allow for additional elements not in the MODS schema?

Thank you,

Jenn Riley, on behalf of the MODS/MADS Editorial Committee
