A flag indicating whether an `id` match is allow, is added to the data frames by
|
|
|
|
(see [link to script to be inserted]()).
|
|
|
|
|
|
|
|
Generic `id`'s (e.g. blank, "SHIP",
|
|
|
|
"MASKSTID") are allowed to match within a `dck`.
|
|
|
|
|
|
|
|
**Match criteria**
|
|
|
|
----------------
|
|
|
|
The following table contains the information used to decide whether `id`'s in a pair, are an allowed match.
|
|
|
|
|
|
|
|
These criteria have been developed by inspection of the paired `id`'s and are therefore likely to be approximate.
|
|
|
|
|
|
|
|
[Damerau–Levenshtein (DL) distance](https://en.wikipedia.org/wiki/Damerau%E2%80%93Levenshtein_distance) is the
|
|
|
|
number of insertions, deletions and swaps necessary to convert one string to another.
|
|
|
|
|
|
|
|
A substring is where one `id` is contained within the other.
|
|
|
|
|
|
|
|
*Italics* in the table below represents the "`id` type".
|
|
|
|
|
|
|
|
Matches of reports where the `id`'s meet the criteria listed below are allow.
