Scope
The aim of the Radiocommunication Data Dictionary (RDD) is to improve the exchange of notification and coordination data between administrations and between administrations and the Radiocommunication Bureau (BR) by: ?C providing a single comprehensive reference source; ?C presenting consistent@ accurate and unambiguous descriptions for the data with@ where appropriate@ references to other ITU documentation containing additional relevant information; ?C providing administrations with a resource for their internal frequency management processes which could include such items as staff training@ exchange of technical data@ upgrading of computer-based systems@ and conference and meeting preparation. The ITU Radiocommunication Assembly@ considering a) that the notification and coordination procedures cover a wide range of radio systems that have been developed over time; b) that there is a need to develop and adopt more precise criteria for frequency sharing and coordination of new and existing systems in both space and terrestrial environments; c) that the impact of rapidly changing technology and the introduction of new services will increase the number of data elements to be uniquely identified and will require a data dictionary to be both flexible and part of a managed system; d) that administrations need to be able to adequately and correctly identify frequency management information and descriptions for many internal processes including staff training@ conference and meeting preparations; e) that the variations in data definitions and units across the different services and frequency bands complicate the unique identification of every data element; f) that for electronic data exchange to be successful the data to be exchanged between administrations and the ITU Radiocommunication Bureau must first be agreed and uniquely identified; g) that Appendix 4 of the Radio Regulations (RR) defines the data sets to be provided@ at different stages or for different categories of services@ to the ITU Radiocommunication Bureau by the administrations@ but does not define in detail the data elements themselves or their formats; h) that more detailed definitions and formats for data elements are spread over a number of ITU-R texts@ including Circular Letters and the Preface to the International Frequency List (IFL)@ and that it would be advisable to concentrate all of this information into a single text; i) that the introduction of a data dictionary containing the radiocommunication terms for uniquely defined data elements associated with the notification process would: ?C aid the introduction of Electronic Data Exchange; ?C simplify the translation process for ITU-R texts and other texts into other languages; ?C make it easier for all administrations to understand the definition of terms regardless of the original language used to define them; ?C improve the accuracy of data supplied by administrations; j) that a data dictionary would need to be maintained to allow for changing technology and future expansion in the number of data elements listed; k) that the existence of a data dictionary would provide assistance to World Radiocommunication Conferences (WRCs) in updating and improving the RR@ in particular Appendix 4@ recognizing a) that a data dictionary will require an on-going procedure for making improvements and keeping it upto- date with developments in radiocommunications@ recommends 1 that the Radiocommunication Data Dictionary (RDD) contained in Annex 1 should be used as a reference to supplement Appendix 4 of the RR for facilitating the advanced publication@ coordination and notification processes of frequency assignments with the ITU Radiocommunication Bureau and in the coordination processes between administrations; 2 that Radiocommunication Study Group 1 should ensure that the RDD is maintained on an on-going basis with the help of a Rapporteur group including participation by the ITU Radiocommunication Bureau.
