**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:
### For Educators:
* 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:username` adds 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.
* `lang:es` or `iso:es` is the way to indicate language in a research note or event. In this example, `es` indicates Spanish.
* `locked` -- locks a wiki page from edits except to moderators and admins. An atypical power tag in that it doesn't follow `key:value` format; [documentation here](https://publiclab.org/wiki/locked)
* `redirect:____` -- redirects a page to the page with the specified ID -- i.e. `redirect:100` would 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:foo` displays 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:foo` adds 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
* `lat:__` and `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.
* `zoom:__` with `lat:__` and `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.
* `place` with `lat:____` and `lon:______` tags, will add your page to the map [on the Places page](/places)
* `prompt:_____` - adds a prompt area below a node, to encourage authors to additionally refine their posts (helpful to avoid long post templates)
### Older powertags
These are still supported but we are seeking to phase them out.
* `sidebar:featured` displays "featured" links and images in the sidebar instead of the usual "related content"
* `style:minimal` hides the wiki toolbar (but it's accessible via a small caret button)
* `style:wide` removes 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:foo` displays recent posts from a Google Group with the name "foo" and a subscription input box
### Prompt powertags
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 `prompt-photo`.
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 `YOURPROMPT`).
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:
* `alert:under-construction` (shows message `This page is under construction`)
**Admins:** to create new alerts, [create a new Feature](/features) 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](https://gist.github.com/jywarren/b1ef7aea7415fad98b085a96c68db9fa).
## 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](/n/15582)
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:
#### Thumbnail grids
Either notes or generally `nodes` (notes + wikis) can be displayed as a grid of thumbnail images. The syntax for this is:
> `[notes:grid:coqui]` (for notes)
> `[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 `https://publiclab.org/questions`.
### Advanced grids
More advanced uses like **activity grids** can be found in this post:
And in the [requesting responses](https://publiclab.org/wiki/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)
### Inline Maps
Maps may be embedded inline, displaying content tagged with `lat:___` and `lon:___` location tags. Read more [about inline maps here](/wiki/inline-maps).
### Inline graphs
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 `prompt`)
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 `prompt`)
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 `prompt`)
The prompts are [better documented here](https://jywarren.github.io/short-code-forms/examples/).
There's also this type of "edit here" prompt:
> `[ edit ]` (but without spaces)
Which generates this type of prompt:
### 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:
* `event:rsvp` `date:YYYY-MM-DD` `rsvp:username`
* `question:foo` `response:foo`
### Tag aliasing
_This feature is for admins only -- please contact firstname.lastname@example.org with questions._
We've created a system for aliasing tags, which serves a number of purposes:
A) **disambiguation** -- we have both `spectrometer` and `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.
1. When looking at https://publiclab.org/tag/spectrometer, you see content tagged with `spectrometry`, and vice versa.
2. 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 `infragram`.
1. When looking at https://publiclab.org/tag/multispectral-imaging, you should see content tagged with `infragram`.
2. 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. ...
