Power tags are an advanced feature which can add extra functions and layout options to your wiki pages (and sometimes research notes). They are entered like regular tags but follow the format
key:value. After adding a power tag, you must refresh the page.
To add tags, look for this box at the bottom of a wiki page or research note:
- Visit this page to learn how to post your assignment, and have student submissions grouped with it: https://publiclab.org/wiki/requesting-responses
General power tags
with:usernameadds a co-author to your research note with a live link to the user's profile page, however, the note itself will not show up under that user's profile.
iso:esis the way to indicate language in a research note or event. In this example,
locked-- locks a wiki page from edits except to moderators and admins. An atypical power tag in that it doesn't follow
key:valueformat; documentation here
redirect:____-- redirects a page to the page with the specified ID -- i.e.
redirect:100would redirect to node 100. Does not affect admins or moderators.
series:____-- displays a message of "This is part of a series on
tagname." with a link to /tag/tagname
alert:___-- will show the feature as alert on that node.
events:foodisplays a listing of research notes tagged with "event" and "foo", and a link to post new notes with those tags in the left sidebar.
parent:fooadds a bar that links back to a parent wiki page
activity:____-- will list the content in an activity grid set to that tag
question:____-- will list the content in as a question on that tag page
lon:__-- will add a location to your note and add a map to the content sidebar. This can also be set in your profile as your user location.
lon:__-- will override the location map zoom to the specified value. Must be between 1 (world) and 18 (building). Also works on your user location for the map on your profile page.
lon:______tags, will add your page to the map on the Places page
prompt:_____- adds a prompt area below a node, to encourage authors to additionally refine their posts (helpful to avoid long post templates)
These are still supported but we are seeking to phase them out.
sidebar:featureddisplays "featured" links and images in the sidebar instead of the usual "related content"
style:minimalhides the wiki toolbar (but it's accessible via a small caret button)
style:wideremoves the 800px width limit from wiki pages, and allows them to flow full page
abtest:____– redirects 50% of page visitors to the page of id given, such as
abtest:1234-- for "user testing" two versions of a page. Admins and moderators not affected.
list:foodisplays recent posts from a Google Group with the name "foo" and a subscription input box
By adding a
prompt:FOO power tag on a node, for example via a link to post such as
https://publiclab.org/post?tags=prompt:photo, the post will displays an HTML feature with (in this example) the name
add_tag('new-tag')) or comments (
add_comment('This post is ____')), allowing a sequence of prompts to be generated which guide the user through a more gradual updating or refinement of their post.
Once a feature named
prompt:______ exists, you may use it on as many posts as you like, and can incorporate it into a posting form link like: https://publiclab.org/post?tags=prompt:YOURPROMPT (substituting your unique prompt name for
You can display alerts using power tags. Admins can create new types of alerts which can be displayed on any wiki or note. An example is
alert:testing-2 -- use this tag on your page, and you'll see an example alert appear at the top of the page content (below the title).
Available alerts using this system are:
This page is under construction)
Admins: to create new alerts, create a new Feature with the name
alert-_____ where the blank is the alert name. For example, for the tag
alert:testing-2, the feature is named
alert-testing-2. The text of the Feature must include the "alert" HTML too, as in this example.
Inline power tags
You can now use "inline" power tags in the middle of a research note or wiki page. The first one is for generating a list of notes for a given tag, and is used in this format:
For more advanced inline tagging, see Advanced Grids
For example, to list all notes tagged with
peru, you can use:
Wiki pages can be listed too:
For a more complex example, you can list all questions on the topic of "infragram" using:
Either notes or generally
nodes (notes + wikis) can be displayed as a grid of thumbnail images. The syntax for this is:
[nodes:grid:coqui](for notes + wikis)
To create a button with text on top that links somewhere outside of publiclab, use:
The above creates a button with a "foo" on top of a button that links to Google. For a button that links somewhere on the site, you can use something like:
The above creates a button with the text
foo on top that links to: "[link you are currently on, you can find this on your address bar]/questions". So if I'm on
https://publiclab.org, this links to
More advanced uses like activity grids can be found in this post:
And in the requesting responses documentation.
Inline People Lists
[people:organizer] -- will display any people tagged as organizers. Add profile tags on your profile page (admins can do this for anyone)

Maps may be embedded inline, displaying content tagged with
lon:___ location tags. Read more about inline maps here.
This feature is still in testing, but allows display of a CSV file as a graph:
[graph:/i/25356.csv] will display:
Prompts let us offer a place on a wiki page where a reader can enter text and it's directly inserted into the text of the wiki page just above the prompt.
[prompt :text:Placeholder text] (without space after
That looks like this when saved:
We can also ask for longer-form text input with the keyword
paragraph -- but be aware that the "placeholder text" can only hold letters, numbers and spaces -- no punctuation (yet):
[prompt :paragraph:Placeholder text] (without space after
That looks like this when saved:
Two identical prompts on one page can cause trouble, but if you add a unique id, you can get around that:
[prompt :text:Placeholder text:UNIQUE-ID] (without space after
The prompts are better documented here.
There's also this type of "edit here" prompt:
[ edit ](but without spaces)
Which generates this type of prompt:
Edit this page to help complete it!
Automated power tags, not for manual adding
You might see some of these being generated automatically, like when checking the box for a Research Note to be an "Event" or a "question" or when awarding Barnstars to someone's Research Note. Don't manually add these:
This feature is for admins only -- please contact email@example.com with questions.
We've created a system for aliasing tags, which serves a number of purposes:
A) disambiguation -- we have both
spectrometry -- as of recently, we'd prefer
spectrometry. So we make each the alias of the other, and the two become somewhat (but not completely) interchangeable on the site.
- When looking at https://publiclab.org/tag/spectrometer, you see content tagged with
spectrometry, and vice versa.
- Email notifications do not yet take advantage of aliasing, but may at some point (see below).
B) subcategories --
multispectral-imaging contains and is broader than
- When looking at https://publiclab.org/tag/multispectral-imaging, you should see content tagged with
- When looking at https://publiclab.org/tag/infragram, you should NOT see content tagged with
multispectral-imaging-- your query is more specific than that.
Some aliasing features are more complex and not complete yet.
Email subscriptions - when people subscribe to a tag, they should receive emails when content is posted using a tag that is a (more generalized) alias of the subscribed-to tag.
