I Dati Strutturati su Commons

I Dati strutturati su Commons sono informazioni multilingua su un file multimediale che possono essere capiti da umani e con abbastanza coerenza da poter anche essere elaborati uniformemente da macchine.

Una breve introduzione per principianti sui Dati Strutturati di Commons (3 minuti 43 secondi)

Le basi

Ogni pagina di file multimediali su Wikimedia Commons ha una scheda 'Informazioni file' e una 'Dati strutturati'.

Vediamo un semplice esempio di un'immagine di qualità su Wikimedia Commons: Würfelzucker (2018).

Aggiungere descrizioni multilingue ai file

Nella scheda Informazioni file puoi aggiungere una didascalia del file in varie lingue: una breve, concreta descrizione del file, senza collegamenti o wikitesto. Queste didascalie rendono più facile trovare il file con una ricerca.

Cosa è raffigurato (mostrato) in un file?

Nella scheda Dati strutturati puoi indicare quello che è raffigurato ("mostrato") nel file. In questo caso: dodici zollette di zucchero bianco. L'animazione sottostante mostra come gli elementi che descrivono l'immagine sono multilingua. Puoi vedere i dati strutturati in differenti idiomi cambiando le tue impostazioni di lingua dell'interfaccia.
Per altre informazioni vedi Commons:Depicts.

Altre dichiarazioni relative a un file

Inoltre, nella scheda Dati strutturati, puoi aggiungere ulteriori informazioni descrittive sul file. Quest'esempio descrive il creatore, la licenza e la valutazione della qualità.
Altre informazioni: vedi Commons:Statements.

What Structured Data on Commons does

Structured data on Commons improves access, searchability, exploration and provides new ways to use the content.

Improving accessibility

Multilingual: Provides labels in over 300 languages which are added automatically.
Accessibility: Provides information that makes content more accessible to users with specific needs e.g. blind and partially sighted.

New ways to find content

Searchability: Allows people to easily find content through better descriptions of what they depict.

New ways to explore and use content

Connect knowledge from different sources: Allows content from many sources together to provide new ways to explore and visualise a subject.
Explore collections and topics: Collates content to provide new ways to explore collections and topics.
Usable by other websites and services: SDC data is free and machine readable meaning and ready to be used in apps and other content.

Improving the quality of information

Data with references: Data can reference to its sources, allowing you to see the original creator of the information and corroboration by third parties.
Queryable: Allows queries to check data quality across 1,000s of files at once, allowing people to more easily identify and correct missing, out of date or incorrect information.

A few easy ways to start

Upload a new, freely licensed file to Wikimedia Commons. You will be prompted to add multilingual file captions (help page) and depicts statements (help page).
Add structured data to some high-quality images supported by a Wikimedia chapter, via the ISA Tool. (You must log in with a Wikimedia account here.)

Get in touch

Use the talk page of Structured Data on Commons to ask questions.
Report bugs and post feature requests on Phabricator (Help).

Tools to add structured data to files

AC/DC ("Add to Commons, Descriptive Claims") is a Wikimedia Commons gadget to help with batch editing. It allows adding statements to a group of files (for example a category).

Cat2Data is a beginner-friendly user script for adding statements to all files in a category.

Depictor lets you add depicts statements using a game-like interface. You can customize it using specific categories or SPARQL queries.

Image Annotator is a tool that runs image annotation campaigns on Wikimedia Commons.

ISA is a tool to help beginners to add depicts statements and multilingual captions to files.

OpenRefine is a powerful and flexible tool to add structured data to Wikimedia Commons files in batch (from OpenRefine 3.6).

SDC is a user script similar to Cat-a-lot that allows adding limited number of structured data statements to files in a category.

Info for developers

Development of Structured Data on Commons is tracked on Phabricator.

Structured Data on Commons is powered by the Wikibase software. Data can be accessed via API; see mw:Wikibase/API for documentation.

The extension used for structured data is WikibaseMediaInfo.

Domande frequenti

What kind of structured data should I add? How should I describe a certain file in structured data?

For best practices on Depicts statements, see Commons:Depicts.
For inspiration and examples of other statements, please check the Modeling pages. Feel free to ask questions there and contribute to the documentation yourself. The data model of Structured Data on Commons is a work in progress and is designed by the Wikimedia Commons community.

How can I find files that already have structured data?

You can use the Wikimedia Commons search function to find files with structured data. A few examples:

You can also use the site Commons Walkabout, which provides a drill-down-style browsing interface for Commons Structured Data.

How can I add structured data to many files at once?

You can use the tools mentioned on this page; see above.
