Introduction

Semantic Result Formats (SRF) is a MediaWiki extension, used in conjunction with the Semantic MediaWiki extension, that bundles a number of further result formats for SMW's inline queries. The individual formats can be added to the installation independently. (Mediawiki.org extension page, June 12 2013).

By default, semantic Mediawiki displays results with tables using a column for each query item. A simple example is below:

This code:

{{#ask: [[Category:Software information]]
| ?Is developed by
}}

... will produce this table:

	Is developed by
Mediawiki	MediaWiki foundation and MediaWiki volunteers
Some software	Many

Semantic Result Formats adds other visualization types. Most of these are based on various JavaScript libraries, such as D3.

Examples

Simple lists

This code

{{#ask: [[Category:Software information]]

• Some software (Is developed by Many)

List of parameters:

⧼validator-describe-header-parameter⧽	⧼validator-describe-header-type⧽	⧼validator-describe-header-default⧽	⧼validator-describe-header-description⧽
distribution	⧼validator-type-boolean⧽	no	Instead of displaying all values, count their occurrences, and show these.
distributionsort	⧼validator-type-string⧽	none	Sort the value distribution by occurrence count.
distributionlimit	⧼validator-type-integer⧽	no	Limit the value distribution to the count of only some values.
aggregation	⧼validator-type-string⧽	subject	Specify to what the aggregation should relate to
min	⧼validator-type-integer⧽	no	The minimum value to show on the Y-axis
charttype	⧼validator-type-string⧽	treemap	Available chart type
height	⧼validator-type-integer⧽	400	Specify the height (in pixels) of a chart or graph
width	⧼validator-type-string⧽	100%	Specify the width (in pixels or percent) of a chart or graph
charttitle	⧼validator-type-string⧽	⧼validator-describe-empty⧽	The title of the chart
charttext	⧼validator-type-string⧽	⧼validator-describe-empty⧽	Descriptive chart text
class	⧼validator-type-string⧽	⧼validator-describe-empty⧽	Specify an additional cascading style sheet class
datalabels	⧼validator-type-string⧽	none	Chart/graph data labels
colorscheme	⧼validator-type-string⧽	⧼validator-describe-empty⧽	Select a color scheme
chartcolor	⧼validator-type-string⧽	⧼validator-describe-empty⧽	Assign individual chart colors

{{#ask: [[Category:MediaWiki extension]]
| ?Is developed by
|format=d3chart
|distribution=yes
|mainlabel=-
|charttype=bubble
|headers=show
|link=all
|charttitle= SMW developers
|datalabels=chart
}}

Notice the use of the following parameters:

• distribution=yes will count occurences
• mainlabel=- will exclude the count of the pages themselves

We roughly get the same information as in the word cloud.

The result of not using mainlabel=- is below:

{{#ask: [[Category:MediaWiki extension]][[Is developed by::+]]
| ?Is developed by
|format=d3chart
|distribution=yes
|charttype=bubble
|headers=show
|link=all
|charttitle= SMW developers
|datalabels=chart
}}
