This ticket follows work done in #1226 to enhance ISBN and ISSN searches. After deployment to production, the ILL team has reported a few anomalies related to ISSN searches specifically:
11417161 vs. 1141-7161
In this case, our current metadata mapping for the 022 field includes both $a and $y which resulted in this record's ISSN being stored as 1141-7161 0008-0020
This ticket follows work done in #1226 to enhance ISBN and ISSN searches. After deployment to production, the ILL team has reported a few anomalies related to ISSN searches specifically:
0048671X vs. 0048-671X In this case, I suspect the inclusion of "X" may be breaking the pattern we expected. The ISSN specification does allow X in addition to numbers and hyphens.
NOTE: "X" is a valid character in the ISBN specification also.
11417161 vs. 1141-7161 In this case, our current metadata mapping for the 022 field includes both $a and $y which resulted in this record's ISSN being stored as
1141-7161 0008-0020
For better formatting, we should revise the mapping to be 022a AND 022y so that each value is a separate entry such as follows:
1141-7161
0008-0020
