Clipboard
The clipboard is used for many things in KnolCase besides coping and pasting
text.
You can cut, copy and paste topics between folders.
When editing a topic, you can copy and paste statements, properties, and values.
You can also add pictures to topics using the clipboard.
KnolCase has a number of plug-ins that can be activated by pasting URLs into
the search box or a topic, letting you import information from other sites
or applications in a quick and easy manner.
Pictures
"" it is said.
You can add pictures to a topic by selecting a topic and pasting an image URL
into it (i.e. a URL ending with .jpg, .jpeg, .gif, .png, .mp4, .webm, .webp, or .avif).
This adds the picture to the photo gallery of the topic.
You can browse the photo gallery by clicking on the photo to the right in the
topic card.
To get the URL for a picture on any webpage, right-click on the image and
select "Copy image address" in the context menu (Chrome).
Pictures on the internet often disappear after a short time. To prevent the
pictures in your case topics from disappearing, you can cache the images on the
SLING media cache service by selecting "Cache images" in the KnolCase menu
(more_vert) in the top right-hand corner.
Then all the images in the case file will be cached in the background and you
will still be able to view them after they have disappeared from their original
location.
Some sites do not allow
which prevents images from these sites from being displayed properly in KnolCase.
In this case, you can paste the image into the topic instead of just the image URL.
You can copy an image by right-clicking on an image on a webpage and selecting
"Copy image" in the context menu (Chrome).
When you paste an image into a topic, it will first be stored on
drive.ringgaard.com using a randomized URL, and then this image is added to the
topic.
You can also paste gallery URLs into a topic. A gallery URL starts with
"gallery:" followed by a list of image URLs separated by space. This format is
supported by the
Reddit photo search tool.
Albums from Reddit and Imgur are also supported.
You can search for images for a topic by clicking the
image_search button on the topic toolbar.
Articles
Pasting a URL from an article or webpage into the search box will create a
new topic for this page. You can also select a topic and paste the URL to add
information to an existing topic.
This is useful for keeping references to webpages and articles where you have
found information about a topic.
KnolCase uses the meta tags from the webpage to create a topic with
information about the page.
It supports Facebook OpenGraph, Twitter Cards, JSON-LD, Dublin Core, Sailthru,
as well as a number of generic meta tags:
- title
- description
- webpage type
- summary
- language
- author
- image
- canonical url
- publisher
- publication date
KnolCase has a database of more than 3000 news sites with their Wikidata QIDs
to identify the publisher of a webpage.
For example, if you want to document the source for some fact in a topic, you
can add a
qualifier with the source:
- Press Enter to make room for a new statement
- Press Space on the new line to start a qualifier
- Type 'source' and then Tab to add a property
- Paste the URL for the source and press Tab.
This will create a new topic for the web article with meta data and add this as the source.
Data tables
You can import tables from spreadsheets by copying some rows and columns
into the clipboard and pasting these into a folder in KnolCase.
You can copy data from any source that supports comma-separated or tab-separated
values (CVS/TSV format).
The first row should contain the property/column names. These can be property
ids (PIDs) or property names.
Each of the remaining rows are imported as a new topic.
If a column name ends with #, e.g. ID#, it is expected to contain item or topic
ids.
Otherwise, the value is parsed according to the data type of the property, e.g.
dates, number, URLs, quantities, etc.
Plug-ins
KnolCase has a number of plug-ins.
These are extensions that are loaded on-the-fly when you paste a URL
that matches the plug-in URL pattern into the search box or a topic.
If you paste a URL into the search box you can select the plug-in in the search
results. This will add a new topic produced by the plug-on to the current folder.
Pasting a URL matching a plug-in into a topic will add the retrieved information
from the plug-in to the selected topic.
External references are checked against the cross-reference register in KnolBase
and the topic is extended with any matches found.
Pictures, tables, and articles are examples of plug-ins that are used for
importing data through the clipboard, but KnolCase also has more specialized
plug-ins:
