How to sequence, numerate and interject files to maintain order

Hello:

I am new to Omeka and we have a question as to how to numerate, interject and sequence files to maintain a specific order in the collections side of Omeka. We are currently using the first four letters of the artist's name and following, a suffix of 001-100. For example, raph003.jpg for the third image of the Raphael collection. We can name all our files sequentially and I am hoping the Omeka will preserve the order that we name them in. Is this correct? And our second most significant question: there are times that we find additional images to interject into our collection. We thought of the idea of adding an a-z at the end of the file name to preserve the order of the collection. An example of this interjection would be raph003b.jpg for the second image interjected after Raphael image number 3. Will Omeka respect this numeration? Or do you have a better idea how to sequence properly files with the ability to continually interject additional files? Thank you very much for our considerations and response.

It depends a little bit on how you structure the site, but one way or another what you describe can happen.

Items in Omeka can have any number of files associated with them, and the files can be rearranged into whatever order you need.

When files are added to items, internally they get a new filename, but the original filename is also maintained in the database.

With the ItemOrder plugin, you can also reorder the items within a collection.

The upshot is that Omeka pretty much ignores original filenames, though they are still present. Instead ordering happens manually either on files within an item, or on items within a collection.
