It typically maps the bits into commonly recognized data types such as character, integer, and real and into groups of these data types. It associates these with higher-level meanings: this includes the description of the, possibly complex, ways objects are interrelated (for example, Representation Information could indicate that three numbers represent temperature, latitude and longitude; and they are expressed in degrees Celsius and angular degrees; and they are interrelated in that the temperature is measured at the specified longitude/latitude).<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB>The Representation Information accompanying a physical object like a moon rock may give additional meaning, as a result of some analysis, to the physically observable attributes of the rock. This information may have been developed over time and the results, if provided, would be part of the Information Object.<o:p></o:p></span></p><p class=MsoNormal><b><span lang=EN-GB>There will be special cases where, for a specific Data Object and a specific Designated Community, the Knowledge Base of the Designated Community is adequate for its members to understand or use the Data Object. In such cases the Representation Information could be the statement that no additional Representation Information is needed for that specific Designated Community at this time. Of course, the Knowledge Base of the Designated Community may change over time and additional Representation Information may then be required. In order to satisfy the Mandatory Requirements, the Archive should ensure that appropriate Representation Information will be available in future, for example details of specific software required or semantics, such as the meaning of spreadsheet columns, which are currently common knowledge. Therefore, any Representation Information that can be gathered at ingest should be included since it will likely be costlier to rediscover and add it at a later time.<o:p></o:p></span></b></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB>Regards<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB>..David<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> MOIMS-DAI <<a href="mailto:moims-dai-bounces@mailman.ccsds.org">moims-dai-bounces@mailman.ccsds.org</a>> <b>On Behalf Of </b>David Giaretta<br><b>Sent:</b> 27 May 2019 20:28<br><b>To:</b> MOIMS-DAI List <<a href="mailto:moims-dai@mailman.ccsds.org">moims-dai@mailman.ccsds.org</a>><br><b>Subject:</b> [Moims-dai] Reminder of Skype call tomorrow<o:p></o:p></p></div></div><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-GB><o:p> </o:p></span></p><p class=MsoPlainText>Meeting: 10:00 Tuesday (EST), 1500 UK time, 1600 European time <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>Join it by clicking the link:<o:p></o:p></p><p class=MsoPlainText><a href="https://join.skype.com/ykyu5SIPhSnD">https://join.skype.com/ykyu5SIPhSnD</a><o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>*Don't have Skype yet?
