Help:Contributing/semanticDynamicContent

Semantic dynamic content renders item data on a wiki page at view time. Edit the item once; every page that renders its statements updates. The Wikibase client provides two parser functions; every example below is live against real items.

The two parser functions

Both take a property — a P-number or its label — and render its statements. The difference is the output form:

| Function | Output | |----------|--------| | #statements | All statements as rich wikitext: values link to their items, monolingual text keeps its language. | | #property | The same statements as escaped plain text: no links, no language markup. |

Same property on Q96 (quotation, one statement per language):

You type	You get
{{#property:P2|from=Q96}}	The Analytical Engine has no pretensions whatever to originate anything. It can do whatever we know how to order it to perform., La machine analytique ne prétend nullement être à l'origine de quoi que ce soit. Elle peut faire tout ce que nous savons lui ordonner d'exécuter., La analiza maŝino tute ne pretendas origini ion ajn. Ĝi povas fari ĉion, kion ni scias ordoni al ĝi plenumi.
{{#statements:P2|from=Q96}}	The Analytical Engine has no pretensions whatever to originate anything.

Examples

Running example: Q99 (Factorial in Python). The from= argument names the entity; the property can be a P-number or a label.

What you want	You type	You get
Instance	{{#statements:P1|from=Q99}}	code snippet
Programming language	{{#statements:P5|from=Q99}}	Python
Code source	{{#statements:P3|from=Q99}}	factorial = lambda n: 1 if n <= 1 else n * factorial(n - 1)
Attributed to	{{#statements:P6|from=Q99}}	Ada Lovelace
By label instead of P-number	{{#statements:instance of|from=Q99}}	code snippet
Another entity — Q55 (Markdown)	{{#statements:P1|from=Q55}}	programming language

Sitelinks: pages ↔ items

A sitelink is a page title on the wikibase site stored on an item. It maps the page to the item; the item page then shows the link in its Sitelinks section. Without from=, a parser function uses the item sitelinked to the current page.

Live pairs on this wiki: Q55 (Markdown) ↔ Cheatsheets:Markdown, Q77 (SPARQL) ↔ Cheatsheets:SPARQL.

To link a page: open the item, add the page title in the Sitelinks section (site wikibase). Or use the API: action=wbsetsitelink with linksite=wikibase.

Gotchas

An item with no statements renders nothing — empty output is not an error. Q94 (Ada Lovelace) has no statements:

You type	You get
{{#statements:P1|from=Q94}}	person

An unknown property is an explicit error, not empty output — P999 does not exist:

You type	You get
{{#statements:P999|from=Q55}}

Without from= the page must be sitelinked to an item. This page is not linked, so {{#statements:P1}} on it renders nothing. Link the page to an item (see Sitelinks above) to use the short form.

Limits

Lua modules ({{#invoke:Wikibase}}) are not available — the Scribunto extension is not installed. Use the parser functions above.
