I'm forwarding this message to the solrmarc-tech list; perhaps someone there has some experience with this problem.

Subject: [VuFind-Tech] alphabetic virtual fields in marc record

I'm importing Marc data to vufind using the same export file we use to export to Summon, as I'd like to keep the two in sync and also only have to generate a single export file from our LMS (alpha). The marc records include virtual fields, in particular for location, collection and physical type, with subfield contents that doesn't occur anywhere else in the record.. These virtual fields have alphabetic names (eg LOC1) and some of the subfields have numeric names (eg $5). The parser for the marc.properties file assumes that field names are numeric and  subfield names alphabetic, so it won't use these fields (though it rather surprisingly doesn't generate any error messages when it meets them).

Has anyone else run into this situation and found a tweak to deal with it? As I wrote above I'd rather not modify the original Marc which is used for export to Summon.

Thanks
Graham
