This is a plugin for Obsidian (https://obsidian.md). It allows you to open and annotate PDF and EPUB files.
The plugin is based on https://web.hypothes.is/, but modified to store the annotations in a local markdown file instead of on the internet.
Warning! In the above gif I use Dataview syntax to specify the annotation-target. If you do not have the dataview plugin installed, you must instead write the annotation-target in the frontmatter, like this:
---
annotation-target: https://arxiv.org/pdf/2104.13478.pdf
---- Plugin doesn't work on iOS 16.3 or higher. Follow #289 issue state up to date.
- Reader doesn't show annotations if they were changed on different platforms.
Add the property annotation-target to the frontmatter of your obsidian note, with a value corresponding to the location of the EPUB/PDF file.
The location can either be a file in the vault (such as Pdfs/mypdf.pdf), or online (such as https://arxiv.org/pdf/2104.13478.pdf)
Then you can, in the open note pane, select "more options" (the three dots in the top right), and a new option "annotate" should be available.
The plugin automatically tries to determine whether the file is an epub or pdf based on the file path, but in case this doesn't work,
you can also add the property annotation-target-type and specify whether it is epub or pdf manually.
If you have dataview installed, then you can also specify the annotation target with a dataview attribute. In this case, obsidian-style links can be used instead of a plain-text path.
WARNING! Don't rename an original pdf or epub file! The plugin is going to lose the connection between annotations and file in that case.
Annotation is self-explanatory. Select text with your mouse to get started.
In the future, it would be nice to add colored highlights and image/region highlights. These features will have to be added to hypothes.is first, however. See these relevant issues: hypothesis/product-backlog#198, hypothesis/product-backlog#669
To return to the regular obsidian markdown editing mode, you can select more options → Open as MD.
Each annotation has an associated quote block with a block reference. Be careful with modifying these blocks.
Minor edits to PREFIX, HIGHLIGHT, and POSTFIX are typically ok. But if the edits are too major, hypothesis may no longer be able to identify the corresponding text.
The COMMENT region can be freely edited. (but ensure that it is still part of the quote block.)
The TAGS region should consist of a comma-separated list of obsidian tags. (like #tag1, #tag2, #tag3)
The plugin has built-in dark mode support. To toggle dark mode, select more options → Toggle Dark Mode while annotating.
You can also tweak the dark mode behavior in the settings tab for the plugin.
An obsidian link to an annotation block-reference will, when clicked, open the corresponding file and scroll to the associated highlight. If the file is already open in a pane, then the link will cause the existing pane to scroll instead.

0.2.1 (2022-03-06) BRAT release Basic web and video annotation
annotation-target-typecan now take on the valueswebandvideo.- With
webthe annotation target can (in theory) be any website. Some work better than others. Link navigation does not work. - With
video, only youtube links are supported. In order to use this feature, a link to a zip file with the annotator.tv resources must be provided in the plugin settings. It cannot be bundled with the plugin since that would most likely violate copyright.- You can ask someone for a link, or generate it yourself by making an account at annotate.tv, signing in, going to https://annotate.tv/videos/620d5a42b9ab630009bf3e31#, and downloading the website using the Save All Resources chrome extension, uploading it to google drive, and generating a direct link.
- Other improvements:
- Some behind-the-scenes changes have been made so that the hypothes.is version can be more easily upgraded in the future.

- Drag and drop has been improved. The drop handlers are now unloaded when the plugin is unloaded. The issues regarding interferrence with other Drag and Drop functionality are hopefully also resolved. (See Issue #50)
