Extension:WikiLexicalData

In a standard MediaWiki installation, all the text of a page is entered in one field, and stored in one entry of the database (page_text).

Wikidata allows to configure some namespaces to use several fields of different types (text, Combobox, etc.) on one wikipage and to store these fields in a structured database.

OmegaWiki is the only implementation of Wikidata so far. The structured database used at OmegaWiki is explained at http://www.omegawiki.org/Help:OmegaWiki_database_layout

Installation
You can either install with an existing copy of a Wikidata database (for example with the OmegaWiki database, see ), or install from scratch on any MediaWiki installation, as explained below.


 * 1) Checkout a copy of the latest "Wikidata" extension
 * 2) * from the previous folder, go into mywiki/extensions/ and execute:
 * 3) In order to create the tables in the database relating to Wikidata
 * go to
 * run
 * you can change the prefix and the datasetname to whatever you like. It has not been tested, but it should work...

Configuration
require_once("$IP/extensions/Wikidata/App.php");
 * Edit you LocalSettings.php and add,

$wgCapitalLinks = false;

$wgExtraNamespaces = array(       16 => 'Expression',        17 => 'Expression_talk',        24 => 'DefinedMeaning',        25 => 'DefinedMeaning_talk', );

$wdHandlerPath = "$IP/extensions/Wikidata/OmegaWiki/"; $wdHandlerClasses = array(       24 => 'DefinedMeaning',        16 => 'OmegaWiki', );

$wgDefaultClassMids = array(37); $wgIso639_3CollectionId = 35;
 * Also add the following (the numbers may vary), as suggested by the install script:
 * $wgDefaultClassMids should correspond to the DM number of the expression called "lexical item".
 * If you edit that expression, in the Section "Class attributes", you can add annotations that will be available for all languages. For example:
 * - Level: SynTrans, Attribute: IPA , Type: Plain Text. Note: you have to define the word "IPA" first
 * - Level: SynTrans, Attribute: etymology , Type: Translatable Text.
 * - Level: SynTrans, Attribute: part of speech , Type: Option list.
 * - Level: DefinedMeaning, Attribute: image , Type: Link.

Languages

 * To add other languages
 * Use the language manager ( Special:Languages )
 * If you add a DM for that language, and add it to the "ISO 639-3 collection" with its ISO code, it will be used to translate the language name according to the interface language ( Use Special:ImportLangNames ).

User rights
Default user rights are as follows: $wgGroupPermissions['wikidata-omega']['editwikidata-uw'] = true; $wgGroupPermissions['wikidata-omega']['deletewikidata-uw'] = true; $wgGroupPermissions['wikidata-copy']['wikidata-copy'] = true; $wgGroupPermissions['wikidata-omega']['wikidata-copy'] = true; $wgGroupPermissions['bureaucrat']['languagenames'] = true; $wgGroupPermissions['bureaucrat']['addcollection'] = true; $wgGroupPermissions['bureaucrat']['editClassAttributes'] = true; $wgGroupPermissions['bureaucrat']['exporttsv'] = true; $wgGroupPermissions['bureaucrat']['importtsv'] = true;


 * : rights to edit the Wikidata pages and add new data. This permission can be given to anonymous users.
 * : rights to modify existing data, such as change a definition or remove a translation.
 * : rights to add new languages via Special:Languages, and update the translations via Special:ImportLangNames.
 * : rights to add a collection via Special:AddCollection.
 * : rights to add attributes to a class.

Note
It is possible to use Wikidata for something else than OmegaWiki (e.g. Wikispecies, Wikicommons, or any other very structured data). However, since Wikidata was developed mainly with OmegaWiki in mind, it would need some work to separate what is specific to OmegaWiki from what could be reused in another project.
