I want to store person / company contacts with addresses and relations. Addresses can have multiple lines for streets, phonenumbers and emails. Would be also nice to have some kind of export feature.
Contacthandling seems like a common task, so i want to know how others are doing this job.
I had a look at the following gems and applications:
demonstrates a reference implementation for handling countries, regions, and addresses
Encapsulates the composed of pattern for addresses into any easy to use library
Rails plugin providing VCard like contact and address models and helpers
vPim for rails provides calendaring, scheduling, and contact support for Ruby through the
standard iCalendar and vCard data formats for "personal information" exchange
An address book web application (Rails) that stores phone numbers, addresses, and prints mailing labels
Are you using one of the mentioned gems, can you recommend other gems or do you implement this on your own (why and how)?
