Terms and definitions in the Monthly Production Report

Introduction

The definition document in the current form is updated with the latest enumerations from TE received 12.11.08.

Colour codes:

Green- Changes made from previous version.

Blue - RDL definition agreed upon with TE

Red- TEComments to the existing definitions

Orange – Other comments

Yellow- Typos

Previously object classes were created in a MPR structure instead of simply as classes of ISO 15926. The alterations made do not relate new classes to the MPR structure. The relations are kept by a nomenclature. For instance is the class Adjustment of value previous period creates as classified by a Monthly Production Report Flow Balance Object Class and not an ISO 15926 class. This makes it difficult to reuse this class in for instance a Daily Production report.

Category “Product”, Product Kind Nomenclature

This category contains several new terms relative to TietoEnator’s enumeration “Reporting Product”. The new terms are created in accordance with previous discussions with TE, and are marked as new a term.

Component classes exist in the RDL, but these are not linked to the MPR Product Kind Object Class or to the MPR Product Kind Nomenclature. They are now removed from the XML.
