.. _SpellChecker:

Spell Checker
^^^^^^^^^^^^^

This engines performs spell checking on selected properties.

EDG currently supports the following languages:

* Dutch
* English
* French
* German
* Italian
* Portuguese
* Spanish

To enable spellchecking:

* Navigate to a class having properties to be spellchecked (e.g. class `Person`)

* Select a property to which the spellchecking is applicable (e.g. `job title`).
  Edit it and scroll down to the String Constraints section to add the language
  (e.g., “*” for all supported, “en” two character language only format, or “pt-br” five character language and region format)
  as a value of the `spell check languages` property.
  Internally, this is stored using the ``tosh:spellCheckLang`` property.

Now, when using the ontology as the basis of another asset collection (such as a data graph, taxonomy or reference dataset), data stored in the fields with spellchecking defined will generate warnings if spelling errors are found.
