Portable Contacts (often abbreviated as PoCo) was a proposed 2008 specification for exchange of vCard-compatible contact info using a one-off JSON format, before microformats2, its parsed canonical JSON format, and h-card was specified.
The portablecontacts.net domain died in 2016 and returned in ~2 months as a zombie site (still zombie in 2018), eventually with various bits of plagiarized content on multiple pages that link to a consulting company. See #Site_Death section for details.
There are no known IndieWeb sites publishing or consuming PoCo.
Web pages prior to site death and zombification, thanks to Internet Archive:
- 2016-04-05 archive — last archive of home page before domain expiration
- 2016-05-16 domain expired
- 2016-07-31 https://web.archive.org/web/20160731191234/http://portablecontacts.net:80/ zombie reincarnation started with new WordPress install that eventually redirects to a t.co link (hence unlinked archive.org link).
