i. Abstract

WaterML 2.0 is a standard information model for the representation of water observations data, with the intent of allowing the exchange of such data sets across information systems. Through the use of existing OGC standards, it aims at being an interoperable exchange format that may be re-used to address a range of exchange requirements, some of which are described later in this document. ii. Preface The primary goal of this profile is to capture the semantics of hydrological observational data for data exchange. This will allow hydrological information systems to communicate data between systems and to end users. NOTE - Please note that 2.0.1 is a Corrigendum in which a number of errors have been corrected in the WaterML 2.0 schema. As such, please make sure that your application re-loads the schema from the OGC schema repository and that local copies are not being used. iii.
