9.2.1 Metadata
All LLPGs contain a scoping and metadata statement identifying the content type and degree of frequency to which the LLPG is updated. This information must be recorded by the Authority Address Custodian in the LLPG Metadata Record (DTF7.3.3.1 type 29 Record) and must be transferred to GeoPlace with a Full Supply and subsequently whenever the Authority Address Custodian makes a change to the LLPG metadata Fields.
9.2.2 Conformance statement
A conformance statement is required to be associated with the content and accuracy of each constituent LLPG. One part of the conformance statement is the measure of the completeness of data as compared to another nationally recognised dataset. Currently, a regular linking process is in place to compare the GeoHub to the Valuation Office Agency and Royal Mail data. For details of the linking process and guidance, see Appendix L.
9.2.3 Header and Trailer Record
Each data transfer file shall contain a Header Record and a Trailer Record. The Header Record provides information on the source of the file and the date the file was generated. The Trailer Record provides information on the contents of the file including a count of the number of Records the file contains and some information on the processing order for the transfer file.
