Hi,

I have an older ePub, also built in Sigil, that I am trying to update in this latest version. The requirements for the opf have changed; for example:

Code:
<dc:creator role="aut">Author</dc:creator>
now needs to be:

Code:
<dc:creator opf:role="aut">M. A. Demers</dc:creator>
Problem is, when I try to change my older content opf to read this, as soon as I hit the Save button, Sigil erases the changes and reverts to the old code. This then fails validation because the "opf:" is missing from the element.

I have tried everything I can think of to fix this: saving the file to a new name then making the changes, saving the file as a copy then making the changes, erasing the content via Metadata Editor then re-inputting the data ... nothing is working. Sigil continually erases the new code.

How am I to update this older ePub without having to start from scratch?
It looks like you are trying to convert this ePub from an ePub 2 ePub to an ePub 3 ePub as that sample you gave is not valid ePub 2 code. The solution (in this case) is to do it by hand (text editor) to make the changes. Sigil is not ePub 3 compliant.
