Portable Contacts
This article is a stub. You can help the IndieWeb wiki by expanding it.
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.
Portable Contacts was converged with the OpenSocial Person format, though opensocial.org itself died in 2014, two years before the PoCo site died.
IndieWeb Examples
There are no known IndieWeb sites publishing or consuming PoCo.
IndieWeb sites are alternatively publishing h-card (and hCard).
Using a microformats2 parser, you can get a canonical JSON representation of h-card contact information.
Software Examples
- Friendica open source software supports PoCo, according to a Friendica dev Hypolite (as of May 2024)
