This wiki runs Semantic Mediawiki - an extension that lets you declare triplet links with the current page as the subject, a Property which serves as the predicate, and an object with a type specified by the property.
Semantic mediawiki lets you declare semantic/triplet links within text with a minor extension to wikilinks like [[Property Name::Object]] with a :: delimiter.
To combine fluid semantic properties with more structured information, we additionally make use of Templates and Forms using the Page Forms and Page Schemas extensions.
Component Summary
As a brief summary of how different parts of the wiki are split across different elements:
- Properties - Define the "meaning" of links between pages or external resources. Each requires a data type (Most commonly another Page, but also text, URLs, dates, and so on), and can be linked to an external vocabulary like schema.org
- Templates - Group together multiple properties, and define how they are displayed on a page.
- Forms - Provide an interface for creating/editing pages by filling the values in (potentially multiple) Templates.
- Categories - Define schemas for categories of objects on the wiki that group together a (single) form, template(s), and schemas.
Worked Example
Typically one would define these from "bottom to top" - defining properties, then templates, and so on, but Page Schemas provides an interface that makes it much easier for doing it "top to bottom" by defining a schema that then can be used to generate the relevant forms, templates, and properties. This order gets messier with longer-lived wikis that then reuse properties and templates across categories, but we'll start with a simplified example of creating Category:Resource
Category/Schema
- Page schemas extension example
- Subcategories
- Relationship between schema and instantiation in subpages via generation and potential subsequent editing. (how 2 use wiki histories)
Forms
- Page forms syntax and the relationship between page schemas and page forms
- Forms with multiple templates
- The relationship between a form and the free text in a page
- How a particular form is indicated by a page.
Templates
- Format/Syntax
- Relationship between display and semantic groupings/categories
- Order of operations from page schemas.
- Relationship to more general mediawiki templates
Properties
- Types
- External Schema Integration
Queries/Displaying Data
Asksyntax and usage- inverse property lookup and assignment
