1   Scope

   1.1   General 
   This part of [ISO 28005](/search?q=ISO%C2%A028005) contains technical specifications that facilitate efficient exchange of electronic
     information between ships and shore for coastal transit or port calls. It is intended
     to cover safety and security information requirements related mainly to the relationships
     between the ship and the port and coastal state authorities as defined in this subclause. 
   This part of [ISO 28005](/search?q=ISO%C2%A028005) contains the definition of  core data elements  for use in  electronic port clearance  ( EPC ) messages. It contains definitions of  core data elements  for electronic messaging between ships and shore in the areas of safety, security
     and marine operations. It does not define any structuring of messages or provide any
     guidance on what information is required for a particular purpose; it is rather a
     general data dictionary for safety, security or operation-related maritime information. 
   It is intended for use in  XML  messages and will for that reason differ somewhat from the similar trade data elements
     directory ( TDED ) International Standard, [ISO 7372](/search?q=ISO%C2%A07372). 
   The  core data elements  defined in this part of [ISO 28005](/search?q=ISO%C2%A028005) are specified so that their meaning and interpretation in general are independent
     of the context in which they are used. 
   This part of [ISO 28005](/search?q=ISO%C2%A028005) does not define the message formats required to exchange information.
