Project discussion & development





Welcome to the Wikidata:Wikisource portal for discussing integration of Wikisource and Wikidata. This portal homepage serves as a beginner-friendly overview of Wikidata for the Wikisource community.

  • If you are here to learn how to contribute to efforts, please see How to help.
  • If you are looking for tasks to help out with, please see the Get involved page. This is also where you'll find a list of ambassadors who work with both projects.
  • For information on previous deployment phases of Wikidata for Wikisource, and to discuss proposals and upcoming developments, see Project discussion & development.

What is Wikidata?[edit]

Wikidata is a free knowledge base that can be read and edited by both humans and machines. It does for data what Wikimedia Commons does for media files: it centralizes access to and management of structured data for the various projects that are part of the Wikimedia Foundation family. This means that similar content in different languages, mappings and links between sites, and other elements that are useful to multiple projects only need to be recorded and maintained once, rather than in each of the hundreds of projects.

Structured data also means that content can be organized and stored in a defined way, often in order to encode meaning and preserve relationships between different items. It allows machines to 'read', understand, and process information and, in doing so, opens up a lot of exciting ways for data to be used and re-used!

Wikidata will endeavour to support and provide structure for all the knowledge stored in its sister projects including Wikisource.

Understanding Wikidata[edit]

Instead of articles (the main type of content for most wikis), Wikidata is made up of items. Items are used to represent all the things in human knowledge, including topics, concepts, and objects. For example, the 1988 Summer Olympics, love, Elvis Presley, and gorilla are all items in Wikidata. Each item also has a unique identifier (starting with a Q prefix) and its own page in the Wikidata main namespace. For example, for the items listed above, 1988 Summer Olympics (Q8470), love (Q316), Elvis Presley (Q303) and gorilla (Q36611) are the respective item pages. These pages are where all the data for each item is added, edited, and maintained, including links to other Wikimedia project sites (these are known as sitelinks or interwiki links).

This means that when it comes to capturing and collecting Wikisource data, each author, for example, can be linked to an item on Wikidata, which in turn would then link out to every page for, corresponding to, or about that author on any other Wikimedia project via sitelinks; the item page would also list data statements with facts related to the author (like "date of birth", "native language", etc.). For example, one such author item page could be Douglas Adams (Q42).

Similar to items, statement properties are referenced with unique identifiers starting with a P (instead of a Q); for example, "date of birth" would be represented by date of birth (P569).

What does this mean?[edit]

Wikidata already holds data in many languages that can be re-used on multiple sister projects, and new data is constantly being added. Wikidata also enables content in sister projects to be enriched with additional facts and information (stored as data statements on item pages).

The choice to use this data is left entirely to local communities—future changes to the wiki software will only provide an option to retrieve information from Wikidata if desired.

As mentioned above, Wikidata also offers sister projects the ability to manage sitelinks (aka as interwiki links) in one, centralized place. For all sister projects, sitelinks serve as a replacement for a previous system of interlanguage links that was used to link from a page in one language on Wikisource to an equivalent page in another language, for example the English Wikisource page on The Curse of Minerva to the French Wikisource page La Malédiction de Minerve. These interlanguage links used to be stored locally on each Wikisource page in the wikitext and maintained separately in each language so that if the name of a page changed or was moved, then pages in each language would need to have their links updated to reflect the changes. Sitelinks thereby improve upon this system by having everything stored and managed in Wikidata from an item page, in this case The Curse of Minerva (Q15891516).

It is still possible, however, to keep the links in the wikitext and completely suppress all Wikidata links by using the magicword {{noexternallanglinks}} if desired. The magic word also supports suppression of only specific languages, in the form of {{noexternallanglinks:es|fr|it}} which would suppress only the Spanish, French, and Italian links.
