Online Text Repository (OTR) 
The Online Text Repository (OTR) is a central storage location for texts, and provides services for editing and managing these texts.
The main task of the OTR is to support the creation and translation of texts. The OTR makes translation of texts possible. Terminology is more uniform and texts can easily be reused. This means texts are of high quality right from the start. This also considerably reduces costs for text corrections, such as for spelling mistakes, inconsistent terminology, incorrect style, and so on. Terminology changes can be done from a central location.
The object itself is separated from the texts. Any changes to the object do not influence the texts, and the other way round. This means you can translate the texts independently of the object.
The OTR differentiates between short texts up to 255 characters in length and long texts of any length. Each text is stored once per package. General, frequently recurring texts are included in the OTR basic vocabulary and can be used across all packages. Texts are saved independently of the object that references them.
The texts are identified internally by numbers. The text number identifies a concept, which includes information about alternative spellings (such as abbreviations or length variants), and also translations of the texts and possible localization-specific variations (industry-, country-, or customer-specific variants).
OTR is currently supported by the following applications:
Web Dynpro for ABAP (see Internationalization and Translation)
