Extract metadata from .ped and .map file

Question

[aiteteji]

I want to archive some .ped and associated .map files. But do not know if any, how to extract the embedded metadata in them. These metadata are expected to aid data discovery that helps in the querying of the database to find matching objects.

Anyone has idea if there are standards to use to curate the data, or if there is a code I can use to extract them. Your help will be highly appreciated.

ped and map files can be generated by vcftools --plink from VCF files, so as long as you have the VCF file archived you should be fine.
