Table 32 – Record structure for the LSG Metadata Record (Type 29)
Notes
The language code of BIL must be used in the LSG Metadata Record only to show that both English and Welsh are fully represented on equal terms in the gazetteer.
The character set must always be UTF-8.
Where a Record requires a percentage of completeness, and no Records are present in the authority area – for example there are no Motorways – then a completeness of 100% should be recorded for there being no Records.
