Common Wagn patterns
Some common patterns that Wagneer have found useful:
Discussion cards
Those docs talk about using "+discussion" cards for adding comment cards to other cards. That's becoming a regular pattern, and we often add "+discussion" to type forms by including this:
{{+discussion|open}}
Even if you don't want the discussion to be visible in your card itself, it's accessible in the community subtab of the Related tab.
Commonly used searches
When you want the cards in a Set you can't just use something like RichText+*type or discussion+*right, because you'll get all of the interface associated with sets. However, you don't have to add a new search card, you can just append one of the built-in sorting cards, e.g., RichText+*type+by name or discussion+*right+by update. All new Wagns have had these (and "by create") built in for a while but if your Wagn lacks them, you can copy them from here:
Blogging
{"type": "Blog entry",
"sort":"create",
"dir":"desc"
}
This returns all Blog entries, in the order created, starting with the most recent. Each entry will be closed but you can adjust that views if you like. To make a nicer presentation, include the Search in another card and add whatever you like before/after the Search. Two examples here on wagn.org — we've included a card with links to our blog entries in the sidebar: Wagn News; and we have a card that shows the full text of each entry: Wagn News page.
If you want to be able to draft blog entries privately before publishing them, set "Blog entry+*type+*structure" permissions so that viewing is restricted, and when you're ready to publish the entry, change it's permission to be viewable by Anyone.
To enable commenting, set permission on "Blog entry+*type+*structure" so that it can be commented on by Anyone (or Anyone Signed In if you want to require that). Or, include a discussion card as described above.
You can customize the appearance of your blog extensively using CSS. For two examples, see Ariel Millennium Thornton's journal, and John Abbe's blog.
Wherever you want a link to add new entries, just add add a blog entry. If you want to restrict who can post blog entries (by default anyone with an account will be able to, or anyone at all if your Wagn is open edit), read up on permissions and create a Role for people you want to let blog, then go to the Options tab of your "Blog entry card" and set it so that only people with that role can create Blog entry cards.
RSS
Every Search in Wagn automatically has an RSS feeds, so the Search card returning your blog entries will show up in your browser as having a feed. If you include the Search card elsewhere, you may want to add a visible RSS icon, see Wagn News for an example of this.
Tagging
Tagging is a way for individuals to label things to make them easier to find information later, and for a community to discover or create a common vocabulary of their interests. Delicious made tagging popular for bookmarks, Flickr for photos, and Technorati's standard for tagging blog posts is now in wide use. Tagging was the inspiration for Wagn's compound names; they turned out to be far more powerful than tagging, so of course it's easy to implement tagging in Wagn in some very cool ways. Here's one way we've found that is certainly useful:
We want to include a plus card associated with each thing we're going to tag, that can hold as many tags as we like. We usually give it cardtype Pointer, and call it +tags. You could do this one by one for every card you want to tag, but typically you want to be able to tag a whole category of things — e.g. people, events, projects. So it's easier to create a types for each such category, and include +tags on the form for that cardtype. For an example, see Peer+*type+*structure, open below.
Once cards have tags, then you can use Search and virtual cards to show which cards, or even which cards of a certain cardtype, have that tag.
You can tag something with cards that don't exist yet. When you save you'll see offers to add cards for those tags.
