I have a simple issue I'm sure has been solved, but I don't seem to be phrasing my searches right.
In short, I want to enter data once, and then quote/refer to it in the visible text of a page. Specifically, I want to enter ISBN numbers once and refer to them in two different places. One ISBN number will be for the e-book edition (and thus is in the opf metadata), and the other is for the paperback edition (and thus is not in the metadata). It seems like I could create a custom metadata field to use for the paperback ISBN, but in any case, I can't figure out how to echo that data back in my selected location. Suggestions welcome, inc. pointers to threads that solve this. |

As far as I know you can't 'reference' metadata within the document. Metadata is for the device/app to read.
What's wrong with a simple copy/paste?? K.I.S.S. philosophy is the best philosophy as far as ePubs are concerned. |

Theoretically, it might be possible to use JavaScript in epub3 books to extract metadata information, but, IMHO, that'd be overkill.

There can easily be several to many paperback ISBNs.
Same edition in different formats (sizes such as Trade, Mass market). Same edition with a different publisher. Can occur serially (author changes publisher) or simultaneously (Publishers with restricted regions). Slight changes that you'd think of as a full edition issue (even if just typos, commas) can result in a new ISBN. The ebook might not exactly match ANY paperback or hardback edition!

Believe me, I wish I could. I waste more damn time, with customers, giving me the wrong freaking ISBNs and then having to go fix them in 3+ places. I wish there was a simple, one-step solution, but there isn't any way, even inside an eBook, really (never mind in the meta) to enter something once (other than an image) and then have it fetched and displayed. (Yes, as Doits says, there might be a way in ePUB3, but as he also says, it's overkill.) Sorry. Hitch |

While this is not the requested solution I do like this metadata tool EPub Metadata Editor for viewing a fixing the metadata itself.

@Evil Overlord - have a look at the Function mode for Search & replace in the Calibre Editor.

Thanks for the input, all.
As many have noted, none of these really solves the issue without substantial overkill, so I'll just write this off as 'there is no good solution'. That's an answer, so that's helpful. For those who questioned the need - I produced a book/month, and presently refer to the ISBN in two places in each. An automated system would reduce the risk of not entering the ISBN as required, which currently requires pasting in several places - the metadata, a title page reference (potentially to other ISBNs as well - e-book, paperback, hardcover), and a copyright page reference. These aren't all required, of course, but fit my preferences. It would have been easiest to just enter the data once and let it replicate (as is possible in my ODT document), but if it can't be done, it can't be done (easily). The search and replace is the closest practicable answer, and the one I've been using. |

If you have basic programming skills, you could also write a Sigil/Calibre Python plugin to automate this task.
