Anyone who has ever taken one of my classes knows that I like Omeka. It is very easy to use, and has many nice features. However, one limitation is that it can be difficult to do rapid data entry on many items. For example, if you use the Dropbox plugin to bring in several hundred pictures, and you want to quickly add metadata for them, or if some of the metadata fields are exactly the same (like author of photographer), there is no way (at least that I am aware of) to easily add this data. Thus, I created what I call the quick metadata entry form, which allows you to update Title, Description, Date, Creator, and Rights fields, and allows you to make all values in a collection the same for a given field. Unfortunately, it was not developed as an Omeka plugin.
