Only the type "String" is available to store text, whereas in some case, we need to store a large amount of data.
In Nuxeo, we used to add some configuration in default-repository-config with the largetext type, but since NXP-13179 we want to use core type definition like
<xs:simpleType name="clob"> <xs:restriction base="xs:string"> <xs:maxLength value="999999999" /> </xs:restriction> </xs:simpleType> <xs:element name="note" type="nxs:clob"/>
Such a field type definition, called "CLOB", "Long String" or "Large Text" should be provided in Studio.
