Help:Tabular Data/sv

Tabellarisk data gör så att användare kan skapa CSV-liknande datatabeller och använda dem från andra wikier för att skapa automatiska tabeller, listor och diagram.

To create a new table, go to Wikimedia Commons, and create a new page in the Data namespace with a .tab suffix, such as. Feel free to experiment by creating pages with the Sandbox/&lt;username>/ prefix. For now, page content can only be edited in the raw JSON format and with a basic table editor, but a gadget allows import/export from/to CSV and Excel files. Eventuellt (skrivet 21 november 2016), vi hoppas att det kommer finnas en kalkylblads-liknande editor för att förenkla dataredigering.



Datalicens
All data in the  namespace must explicitly indicate the license of the data. The recommended license is Public Domain, licensed under Creative Commons Zero (CC0) license. To indicate this, every data page must have, which means the data can be used under the CC0 version 1.0, or (at your option) any later version. By editing the data, you agree to the Terms of Use, and you irrevocably agree to release your contribution to the public domain under CC0.

Om det inte går att publicera datan under CC0, stöds också följande licenser:

Alla mallar som hämtar data från icke-CC0-licensierade datauppsättningar behöver följa relevanta tillskrivningsvillkor, därför rekommenderas det starkt att föredra CC0 närhelst möjligt.

Någon gång i framtiden kan listan över licenser som stöds av namnrymden Data expanderas.



Datatyper
Tabular JSON data supports several basic value types. You may also use  instead of the value to mark it as missing.


 * &mdash; A numeric value with an optional fractional part and may use exponential E notation, but cannot include non-numbers like NaN.
 * &mdash; only allows  and   values.
 * &mdash; a text string no longer than 400 characters long. Special characters like new lines  and tabs   are not allowed.
 * &mdash; A multilingual string, represented as an object with keys being language codes (e.g. "en"), and values being a string with above limitations of 400 max chars. For example,  has string values for both English and French.



Toppnivåfält
Tabellarisk data har flera obligatoriska och valfria topp-nivå-element:


 * The required  field must always be set to   string value. For now, tabular data only supports CC0 (Public Domain dedication) license version 1.0 or later. More license support may be available in the future.
 * The required  field must set to an object that contains a list. Each field describes a column of the tabular data. Each field must be an object with mandatory   and   values.
 * The required  field is the name of the column. The value must begin with a letter or an underscore , and must only contain letters, underscores, or digits. This is done so that each header can be easily used from a coding environment like Lua or Vega graphs.
 * The required  field must be set to one of these values: ,  ,  , or.
 * The optional  field is an optional translation for the column's header. If set, it must be a localized string object.
 * The required  field must always be set to a list of lists. Each sub-list must have the same number of elements as headers, and must match the value types.
 * The optional  field must be set to a localized string value - an object with at least one key-value, where the key is a language code (e.g. "en"), and the value is a description string.
 * The optional  field must be a Wiki markup string value that describes the source of the data.

Användning
Det finns två sätt att använda denna data:


 * A Lua script on any wiki can get this data by calling . The function returns tabular data in almost the same format as the original JSON, except that all localized strings will be converted to regular strings, and the license field will also include a localized license name. To get the data in another language, pass language code as the second parameter. To get the data in the original, unmodified form, use "_" as the language code.
 * A Vega graph can get tabular data by using  as the data source url.

On Commons, transcluding a page from the Data namespace, i.e., will render it as an HTML table. To access data directly on a wiki page, you can import (if you don't already have them) the tabular data module (requires the navbar module) and optionally the tabular query template. (requires the before mentioned tabular data module) With these tools you can easily get the value of a single cell.

Exempel
See c:Data:COVID-19 cases in Santa Clara County, California.tab for an example of how the JSON data renders on Commons.



Begränsningar och aha

 * Each string value except the  must be no more than 400 symbols long. Special characters like new lines   and tabs   are not allowed.
 * The overall size of the page may not exceed 2MB.



Administratörsanteckningar

 * Site administrators may customize error messages, such as  to make sure editors know about the CC0-only limitation.



Konvertera data till JSON
There are several tools available for converting other formats to JSON

CSV and TSV

 * convertcsv.com (select "CSV to JSON Array") - Generate output as JSON Array, under 'output options' select option 'if to JSON Array, create array for column names with name'. You will still need to manually add "name": and "type": to each entry in "fields" (see example above for formatting)

XLS

 * xls-to-json
