Extension:Wikibase Repository/es

Wikibase is an extension that allows you to use your wiki as a structured data repository. Its development is part of the Wikidata project. The data can in turn be used in a wiki using the Wikibase Client extension.

Feature overview

 * Creation and maintenance of items
 * Histories and diffs of structured data
 * Labels, descriptions, and aliases for items
 * Rich interface and functionality for managing language links to items
 * Adds the content handler for structured data

Requisitos
requiere:


 * MediaWiki 1.23 o superior
 * PHP 5.3 o superior

Wikibase optionally depends on:


 * Universal Language Selector
 * Babel

Y uno de los siguientes:


 * MySQL o MariaDB 5 o superior
 * SQLite 3 o superior

Instalación
If you want items in the main namespace, then delete or move your Main Page before enabling Wikibase.

Now add the following code to your LocalSettings.php file:

Then run

You will need to run the populateSitesTable.php maintenance script in Wikibase Lib:

The script is by default configured to fetch sites matrix information from meta.wikimedia.org via a https connection. If you have any problems with the script, then try specifying the  option (without the https).

You need to configure which namespaces should be used before the extension will work. Wikibase needs three namespaces: one for items, one for properties and one for queries. Typically these are either three new namespaces, or two new ones and the main namespace being used for items. Both set ups are given in the following. You can also simply add  to your LocalSettings.php (after the require_once of lib/WikibaseLib.php and repo/Wikibase.php).

After that, run  from your MediaWiki root directory.

Note: If the Wikibase extensions are already present when the Mediawiki installation is run, it will add the following lines to LocalSettings.php, which will cause Mediawiki to display  and nothing else:

These lines have to be removed and replaced by the ones stated above.

Setting up items in the main namespace
If you want to set up your items in the main namespace:

If you are also using the query components, then you can add:

Note that if the "Main Page" is still in the Main namespace there will be thrown an exception, at least when you try to access that page. If you see this exception comment out the content model for the Main namespace, and then move the "Main Page" out of Main space without leaving an redirect. Usually the page will be moved to "Project:Main Page". If so the system message Mediawiki:Mainpage should be updated, or a similar message if Mediawiki:Sidebar is changed. Also check if there are other pages in the Main namespace by using Special:Allpages. After the Main namespace is cleansed for other pages you can reenable the content model for Main namespace.

Items in a dedicated item namespace
If you want to set up your items in a namespace of its own, here called :

If you are using (and enabling) the query components of Wikibase, then you can add the following in addition:

HTML5
The extension uses HTML5 specific attributes, and because of this the $wgHtml5 must be set to  in pre MW 1.22. In MW 1.22 and later versions this configurable feature is removed and the returned code is always HTML5.

Configuration
Configuration of is done by assigning to   in your LocalSettings.php file. The options are listed below and their default is set in the. You should not modify the settings file, but can have a look at it to get an idea of how to use the settings, in case the below descriptions do not suffice.

''The extension use the variable name, note the initial prefix  , while configuration of other extensions might use the initial prefix. The difference is important and the configuration will fail if the latter is used.''

Example of how to change a setting:

Available settings:
 * The available settings are documented in extensions/Wikibase/docs/options.wiki

Maintenance scripts
This extension has some maintenance scripts in the  subdirectory. They assume that the extension is installed in the extensions directory of the MediaWiki software (i.e. files are in the  directory), if this is not the case, you can set the   environment variable to the path of your MediaWiki installation and the scripts will use it.

An usual way to set the environment for scripts run by cron jobs is to do something like env 'MW_INSTALL_PATH=/var/www/repo' php &hellip; This should then run whatever php-script you want to append after the php interpreter.

rebuildAllData.php
This script should rebuild all the Wikidata data in secondary storage from articles in Data namespace. You may use it to rebuild data after testing.

deleteAllData.php
This script should delete all the Wikidata data in secondary storage and articles in Data namespace. You may use it to delete the data after testing.

populateSitesTable.php
This script will load the wiki matrix from meta.wikimedia.org and use that information to populate the local  table. This provides Wikibase with the information it needs to connect to other wikis, e.g. to suggest or normalize the titles of pages when creating site links.

extractInterlang.sql
This is an SQL query that extracts interlanguage links from a wiki in a format readable by importInterlang.php. You may use it in a database of a wiki that has interlanguage links, so that you can later import them for testings.

importInterlang.php
This script imports interlanguage links from a file into a wiki, also creating labels in the process. The file is a tab-separated CSV file, in the following format:

page_title    ll_lang   ll_title -архија       cs        Seznam forem vlády -архија       de        Liste der Staatsformen und Regierungssysteme -архија       en        Government#Forms of government -архија       eo        Listo de formoj de registaro -архија       es        Anexo:Formas de gobierno -архија       fr        Liste de formes de gouvernements -архија       jv        Daftar wangun pamaréntahan -архија       ku        Lîsteya pergalên siyasî -архија       mk        Список на општествени уредувања -графија      de        -graphie -графија      en        -graphy -графија      id        -grafi -графија      ka        ...გრაფია -графија      sv        -grafi

The first row of the file is ignored.


 * The first column contains article titles of articles on the base wiki (the wiki the links are linked from).
 * The second column contains language codes of the links.
 * The third column contains article titles of the linked articles.

Script options:


 * : if set, the script will print API requests, responses, and other information.
 * : if set, the script will ignore API errors and continue importing even if it encounters an error.
 * : This should be the language code of the base wiki, the wiki you have extracted interlanguage links from.
 * : The file with interlanguage links, presumably generated by extractInterlang.sql.
 * : Base API url of the wiki you are importing the link into. For example,

Example command line:

To import the test items from extensions/Wikibase/repo/maintenance run

pruneChanges.php
This script is located in Wikibase/repo/maintenance/pruneChanges.php. It allows to prune the Wikibase changes table. If you run it without any parameters, it will delete all changes older than 7 days. To delete all changes older than 1 day run

createBlacklistedItems.php
This script creates blacklisted items in Wikidata Data namespace, typically to create easter eggs and similar. The actual data is hardcoded in the script. You may use it before the item ids reaches the first blacklisted items.

importProperties.php
Maintenance script for importing properties in Wikidata. Usually this will use the example file in en-elements-properties.csv as source while building the example entries. You may also use it to create other entries for testing.

To import the test properties from extensions/Wikibase/repo/maintenance run

rebuildEntityPerPage.php
Maintenance script for rebuilding the items_per_page table.

rebuildTermsSearchKey.php
Maintenance script for rebuilding the search key of the TermSQLCache. The search key is an additional column in the wb_terms table. This column is optional in the table and is used for caseless searches.

searchEntityArtefacts.php
This is a maintenance script that queries the database for entity artifacts. During use the database accumulates failed entries and this script tries to find them and print them.

Internationalization
is fully internationalized. Translation of messages is done through translatewiki.net. The translation for this extension can be found here. To add language values or change existing ones, you should create an account on translatewiki.net, then request permission from the administrators to translate a certain language or languages on this page (this is a very simple process). Once you have permission for a given language, you can log in and add or edit whatever messages you want to in that language.
