![]() ![]() If the reading system cannot process the resource because its format is a bit exotic, it will find here the fallback resource he can process instead.Īs its name indicates, this is a “backbone” where the reading system finds the default reading order of all publication “chapters”. if the file corresponds to a navigation document, cover image, vector graphic or a script. From the properties declared on each item, the reading system will also know its type, e.g. The reading system will only process the files it finds in the list, and knows from their media type (a.k.a. the exhaustive list of all publication (or rendition) resources, including (x)html text chapters, images and videos or audio files, fonts, scripts, css files. Other metadata can be expressed inline, using a generic meta element, or as an external resource via a link element. A fixed-layout publication must be tagged by a specific metadata item in this set. The only required elements in EPUB 3.01 are title, identifier, language and modified, from the Dublin Core set. Onyx) can be expressed as XML elements, from different schemes. ![]() information about the publication (or rendition) content. In this file, the reading system will find: Note : I do other things in Sigil in addition to removing metadata items, such as spell check and ToC adjustments.This XML file carries bibliographic and structural metadata about an EPUB publication (or an EPUB rendition), and is thus the primary source of information about how to process and display that publication. ![]() I did look at it a long time ago but I decided I didn't need it because I could achieve what I wanted with calibre's Modify plugin and Sigil. This program might be of interest => New program: EPub Metadata Editor. Here the settings I have for the Modify plugin. Any Comments that I download and want to keep get moved into a custom column - Blurb/#blurb, which I can edit from the book list, and remove via the Modify plugin. I don't use Comments, firstly because they cannot be edited from the book list, secondly because they end up in dc:description, which cannot be removed by the Modify plugin. calibre puts content of Comments into dc:description, i.e. I use the Comments section for brief observations on some books and the Description section after completing each book to make a brief summary of the concepts that belong to it. Maybe you can convince the authors of these to add options to remove certain metadata. Other than that, there are the Clean Metadata and Cleaning Comment plugins. To do multiple books, the bulk metadata editor has a search and replace function that should be able to clear one field at a time for all the books. I can't think of anything that will remove all unwanted metadata except opening the metadata editor and going through each field and clearing them. Well, I am curious about why you don't want the other metadata, but. > I would like to erase all possible metadata, apart from the four mentioned above.
