Manual:Semantic MediaWiki

Scope and terminology

Semantic MediaWiki (SMW) is a set of MediaWiki extensions that make it possible to collect and query structured data in the wiki. Properties can be added to any wiki page, for example the document owner (Property:Has document owner) or an expiration date (Property:Has expiration date).

The following steps are usually necessary to work with data-based content in your wiki :

1. Define properties: Properties determine which values can be queried in the wiki.
2. Create a template: This creates the output format of the data set on the wiki pages.
3. Create a form: Using this form, Wiki users can comfortably enter their data.
4. Assign a category: Each page that contains a semantic template is usually tagged with a category that was created for this purpose. This, in addition to the properties, provides an important means of querying and filtering the pages.

Define properties

To make information available as data on a wiki page, we create so-called properties. For example, if we want to semantically record customer data, we create a wiki page for each customer. We collect customer data such as location on every customer page. To do this, we create a property that records the location of the customer:

[[Has location::Regensburg]]

Afterwards, we can list all customers at a certain location or all customers with their individual locations in the wiki.

Create a template

Since we often want to display several such properties and their values on one page at the same time, we format a special area that clearly shows the values for each property. This requires a (data) template, which can then be used on any wiki page.

Data template

Create a form

To support our users with data entry tasks, we create an input form. The input form is shown when users switch to the edit mode of a wiki page that has the data template included.

Data entry form

Assign a category

Wiki pages that use data templates are tagged with a category. This category enables the assignment of the input form to the wiki page. The category is also used to query the data collected by the template. The data can then be displayed anywhere in the wiki.

Example

On the following pages, we create an example that collects and displays customer data it in the wiki.

Example: Collect customer data
