file metadata

file metadata

[Christopher Howard]

Hi, I have a bunch of files in various project that have non-descriptive names, but I don't want to change the file names, nor the file contents. It would be nice if there was some way I could display my own description of the file next to the the file listing, say in dired. Do we have any kind of extension, ideally with dired integration, that provides some of kind of file metadata system, or interacts with a third party metadata system?

One approach is to bookmark a file and use a bookmark's annotation to record the metadata.

If you use Bookmark+ then:

You can also use tags, instead of or in addition to an annotation.

You can also use an autofile bookmark, which has the same name as the file.  This is just a wrapper around a file or directory: a way to attach meta information (such as tags or an annotation) to it.  But you can use an autofile bookmark much as you would use a file or directory.

See:

* Annotations: https://www.emacswiki.org/emacs/BookmarkPlus#BookmarkAnnotations

That's a really good question.

You didn't mention your underlying OS or filesystem, although i guess we'd
want emacs to work with whatever metadata system is present.

Do you already have some extra metadata assigned (say with an attribute
called 'description') through (e.g.) ext4?

Oh yes, I do that all the time, that is my main thing. I have too many documents, too many legal entities, employees, reports, and it is not possible to work with the file system only.

System is fully functional, though it requires personal guidance and patience to be installed. Once installed, it works fine, it would fully satisfy your needs.


RCD Notes & Hyperscope for GNU Emacs, The Dynamic Knowledge Repository:
https://gnu.support/gnu-emacs/rcd-notes-for-gnu-emacs/index.html

RCD Notes for GNU Emacs is Dynamic Knowledge Repository designed as envisioned by Doug Engelbart. Backed up by PostgreSQL relational database, RCD Notes provides features such as people management also known as CRM or Customer Relationship Management, ERP or Enterprise Resource Planning, WRS or Website Revision System and Hyperscope Dynamic Knowledge Repository. It uses any kind of Emacs major modes and any kind of lightweight markup languages for editing and writing of any of elementary objects.

Here is small video demonstration:

https://gnu.support/images/2024/10/2024-10-14/2024-10-14-01:48:10.ogv

It has tags, tag types, each tag can have tags, different language,
related person, rank, system is actually extensible on the go, it has
85 different rather fixed properties for each elementary object, plus
unlimited properties, with unlimited property types, types, subtypes,
all extensible and customizable by user. It's fantastic, it is also
good money maker system for me.

I am using ext4, and Emacs 30.0.91 (build 12, x86_64-pc-linux-gnu, GTK+ Version 3.24.41, cairo version 1.18.0) of 2024-10-09. I am running Guix System x86_64.

I do not, but I am opened minded regarding this.

I had a system where I used:

(let ((backup-directory-alist '(("." . "~/denote"))))
  (make-backup-file-name-1 (expand-file-name
  (file-name-with-extension filename "org"))))

...to automatically check for a corresponding denote file with metadata.

Never mind that: breaks the first function.

bookmark+: legacy key syntax in Emacs 30?

[Christopher Howard]

I downloaded the latest files from the wiki but am still getting the same error when I require 'bookmark+.

I do not know much about keymaps at this point, but the offending line is in bookmark+-key.el:

``` elisp
(define-key ctl-x-map "rK" 'bmkp-set-desktop-bookmark)        ; `C-x r K' (also `C-x x K', `C-x x c K')
```

I see in the Emacs 30 documentation at least that define-key is considered now a legacy function, and `keymap-set' is recommended instead. Perhaps something broke in define-key from 29->30, so that it no longer recognizes correctly the legacy string syntax?

I'm CC'ing emacs-devel in hopes that an SME will weigh in on this.

Thatʼs possible, but in this case I canʼt reproduce your error. That
syntax is perfectly legal, and will remain so.

    Christopher> I'm CC'ing emacs-devel in hopes that an SME will weigh in on this.

Does this happen when you byte-compile the bookmark+ files? Or only
when you use the .el files?
