Suggestion: Library locked for everyone's use

[DavidlPORTUGAL]

A feature that Caliber lacks is that it allows you to search and view the book but it is not possible to edit or remove or add other books. It should also be possible to LOCK the folder containing all the books so that they are not deleted locally or by mistake. At least that folder is encrypted or in some way it can be prevented from being edited, deleted or added without permission. It is still not possible to use an official version on Qnap. I remember that Qnap is a European brand and has a lot of strength here. Their concept is to support third-party initiatives as opposed to the competition.

Sugestão: Biblioteca bloqueada para uso de todos

Uma função que falta no Calibre é permitir que se pesquise e se veja o livro mas que não seja possível editar ou remover ou adicionar outros livros. Também devia ser possível BLOQUEAR a pasta que contem todos os livros para que não sejam apagados localmente ou por engano. Pelo menos que essa pasta seja encrypada ou de alguma forma se possa impedir que se edite, elimine ou adicione sem premissões. Continua não sendo possível usar uma versão oficial no Qnap. Lembro que o Qnap é uma marca Europeia e tem muita força por aqui. O conceito deles inclusive é apoiar iniciativas tercerizadas ao contrário da concorrencia.

The feature you are describing sounds a lot like the calibre Content server https://manual.calibre-ebook.com/server.html

If it is indeed the same, then rejoice as it already exists :-)

And it uses a standard Web Browser from any PC with access to the same network the Calibre PC resides.

But they are primary functions of the calibre library manager:



And there is equivalent functionality available from the command-line tools.

Can you describe and explain in detail what you want.

Permission management, access control, and encryption are functions provided by the platform being used… i.e. the Operating & File system.

As others have responded, the calibre server provides a hook into the platform services that provide access control… e.g. to prevent children accessing an adult's only library.

Storage of calibre libraries Calibre is not officially supported on network attached storage of any sort - shared folders, file servers, NAS devices, cloud services etc.

QNAP is Taiwanese, it's subsidiary of the embedded systems specialist IEI Integration.

Back in March you asked what to do with the supplementary (additional) files that come with some books.

A couple of months ago a 'data' folder feature was added to calibre. It's primary purpose is to provide a place where additional files can be stored. There are no restrictions on file names, file types, how many, etc; sub-folders are supported.

Calibre is a single user ebook management system. Not a multi-user library system. Hence the you pretend the files don't exist and the Calibre Library is a per user on the Mac, Windows or Linux. If the computer is used on different logins each user would have their own "calibre library". I've written multiuser databases, lending library systems and document management systems, but calibre is none of these. Primarily it's for storing and managing the books on a portable ereader, or for a similar functionality app on a phone or tablet.

You seem to need a system for a network in an institution. Such do exist.

Also there is the issue of copyright. Unless the ebooks are all public domain or you have a library/institution licence even using the content server is wrong in an institution.

Actual libraries and similar use Borrowbox, Libby, Solar etc. Proper multiuser systems with licence and usage tracking. Calibre is a per user database/manager for ebooks for one person's ereader (or ereading app). Hence the database and ebook files are stored in a user's file space on Windows, Mac and Linux. The actual ebooks are only stored as files because even with DB2, MariaDB, MySQL, Oracle or MS-SQL that makes more sense than "binary blobs" inside the database. So the database has the metadata and information as to where and what the ebook files are called, hence regard them as hidden. Only the GUI is meant to be used and it has "Send to Disk" for devices that Calibre doesn't know how to manage.
It was originally for the Sony ereader, but Sony gave up. The Kobo ereaders work best, but Kindles and many Android ereaders and apps on phones and tablets work too.
