Extension:WikibaseMediaInfo/hi

WikibaseMediaInfo एक के लिए एक्सटेंशन है जो मल्टीमीडिया फ़ाइलों के बारे में संरचित डेटा हैंडल करने के लिए MediaInfo सत्ते जोड़ता है।

एक्सटेंशन चित्र पृष्ठ से हुक हो जाता है। यह एक MediaInfo सत्ते में फ़ाइल के बारे में पूरक मेटाडेटा (कैप्शन्स और चित्रण बयान) रखता है। सदस्य यह डेटा देख, बना, सम्पादित कर, और हटा सकते हैं।

आवश्यकताएँ

 * Wikibase (follow instructions for both client and repo)
 * Wikibase (follow instructions for both client and repo)
 * Wikibase (follow instructions for both client and repo)

स्थापना

 * Ensure CirrusSearch, Wikibase (client and repo) and WikibaseCirrusSearch are set up properly.


 * Add configuration.



MediaInfo का UI
MediaInfo सत्ते उनके संबंधित फ़ाइल पृष्ठों पर तथा UploadWizard के ज़रिए फ़ाइलें अपलोड करते समय दिखाया जा सकता है, और उन्हें वहीं से सम्पादित भी किया जा सकता है।

There are separate sections in the UI for editing captions and statements.

An editing interface for is always shown for default properties (defaults are defined in config). On live commons depicts is the only default property - users are encouraged to say what is depicted by an image. Statements with other properties can be added by the user at will.

शब्दावली


MediaInfo सत्ता
एक विकिबेस सत्ता जिसमें मीडिया फ़ाइलों के बारे में संरचित डेटा होती है। It is stored in a slot on a File page and consists of


 * an ID in the form Mxxx, where xxx is the id of the associated wiki page
 * कैप्शन्स की कोई भी संख्या (हर भाषा के लिए एक)
 * बयानों की कोई भई संख्या

(Note: if there is no caption or statement data then the entity is not stored in the database - in this case it is known as a 'virtual entity')

कैप्शन
टेक्स्ट का एक छोटा हिस्सा जो मीडिया फ़ाइल को वर्णित करता है, और साथ में उसकी भाषा। Used to provide a short description of the file (the same as 'labels' in Wikibase).

Statement
A single fact about a media file consisting of a key-value pair such as  or.

Keys are always a property. Values can be any wikibase datatype.

Strictly, a wikibase 'statement' means a key-value pair (a 'claim') plus a rank (, , or  ) and zero or more documentary references. We don't typically have documentary references for descriptions of files, and all statements have a  rank by default, so in MediaInfo we prefer to use the term 'statement' instead of 'claim'.

Property
A property is a property of a file that can have a value - for example 'depicts' (what an image is a picture of), 'resolution', 'created by', 'license'. Each property has a unique id in wikibase in the form  such as.

Item
An item is a concept, topic, or object with an id - for example on Wikidata the CC0 licence is Q6938433, physics is Q413 and the planet Earth is Q2. Each item has a unique id in wikibase in the form  such as.

क्वालिफ़ायर
A qualifier is a secondary statement that modifies the primary statement. For example an image might have a tree in the foreground and the sea in the background, in which case it could have 2 'depicts' claims associated with it - 'depicts=tree(applies to part=foreground)' and 'depicts=sea(applies to part=background)'.

खोजना


कैप्शन से खोजें
Users can search for files by their MediaInfo captions just as they would search for anything else. For example, if a user uploads a picture of the Eiffel Tower, and enters 'Tour Eiffel' (French) and 'Eiffel Tower' (English) as multilingual file captions, the picture is findable by another user searching for either 'Eiffel Tower' or 'Tour Eiffel'.



दावे/बयान खोजें
Searching for claims/statements happens via WikibaseCirrusSearch keywords, for details see:



खोजने का कार्यान्वयन
When the File page is saved, the following MediaInfo data is written to the Elasticsearch index (all examples use Wikidata Property and Item ids):

- e.g. 'depicts house cat' is stored as
 * Captions data in every language is stored in the  field
 * Claims are stored in the format  as array elements in the   field using the wikibase property ID (and item id, if value is an item)
 * Claims with qualifiers are stored in the  field along with their qualifiers in the format  .  For example, the Mona Lisa painting (Wikidata item Q12418) depicts a sky (Q13217555) in the background (Wikidata property P518). If we arrange this data in a Wikibase claim, it would be: 'depicts sky, applies to part background', which would be stored as
 * Note that claims with qualifiers are also stored without the qualifier, to increase their findability. So, for example, if someone entered the above claim-plus-qualifier, the claim  is also stored, so that someone can find the file by searching for 'depicts sky' alone, as well as by searching for 'depicts sky, applies to part background'.
 * Claims data with qualifiers where the qualifier value is a quantity is stored in the  field in the format , eg. 'depicts human, quantity 1' is stored as.

Note that not all claims are stored. A claim will be indexed in ElasticSearch only if ALL of the following conditions are true:


 * The claim has a real value (i.e. its value is not 'no value' or 'unknown value') AND
 * We know how to process its value for indexing. More value processors may be added in future, but currently we require the claim's value to be either a Q item ID, a string (alphanumeric), or a quantity (numeric) AND
 * the claims's Wikidata property ID is NOT in a configurable list of excluded IDs AND either its property ID is in a configurable list of property IDs that should be indexed  OR its property type is in a configurable list of property types that should be indexed

Note that for a claim's quantities to be stored, the claim must meet all the criteria above AND the property ID for the quantity qualifier must be present in a configurable list of property IDs.



MediaSearch खोज प्रोफ़ाइल
Structured data (captions and statements) are now also included in the default search profile when searching (only) in the  namespace. Search terms like "dog" will also include files where the caption (in the user's language) contains "dog", or contains a statement  (depicts=dog).

For a more elaborate (technical) writeup up the MediaSearch search profile, see the Extension:WikibaseMediaInfo/MediaSearch subpage.

कॉन्फ़िगरेशन
एक्सटेंशन के कॉन्फ़िगरेशन वेरिएबल्स कुँजी-वैल्यू जोड़ियों में पाए जाते हैं। They are documented in more detail in. All config variables are added to.

इस एक्सटेंशन के लिए निम्नलिखित कॉन्फ़िगरेशन विकल्प उपलब्ध हैं:

Config (in LocalSettings.php)

 *   Default wikibase properties that will always be shown, allowing users to add/edit/delete values for them, on the File page/UploadWizard, regardless or not they already have a value. On live Commons this is the  property, as we want to encourage users to fill in values for this in particular. Value is an array of key-value pairs connecting a label name to an existing wikibase database id.


 *   URLs for pages where a user can learn more about particular wikibase properties - if there is a help URL for a particular property then there will be a "learn more" link for that property that leads to the URL from the config.

Other Config

 *   Enables MediaInfo data on UploadWizard when set to.

परीक्षण
PHPUnit tests are located in. You can run tests not requiring the MediaWiki framework (located in ) by running. यह कमांड PHPCS की मदद से कोड स्टाइल जाँच भी चलाता है।

मीडियाविकि फ़्रेमवर्क ( में स्थित) पर निर्भर परीक्षणों को मीडियाविकि के मूल   एंडपॉइंट की मदद से चलाना होता है।

जावास्क्रिप्ट परीक्षण  पर स्थित हैं। आप  की मदद से टर्मिनल से भी परीक्षण चला सकते हैं। Node के संस्करण 6.x का इस्तेमाल किया जाना चाहिए।
