Social Media

Social media

Lots of institutions have a social media presence on such platforms as Twitter and Facebook. Most of these can be expressed using foaf:OnlineAccount and friends.

A social media account can be associated with a person, an organisation, or a project.

We've created the twitterHashtag in the open org namespace. A hashtag can be related to a concept, location, event, or anything. A combination of hashtags may be used in one literal to indicate that it is that combination of hashtags which is associated with that resource.

Having two oo:twitterHashtag properties, however, would indicate that either is used to refer to the same thing (not recommended)

Facebook

TODO: Needs thinking.

Facebook pages and groups aren't online accounts, so don't fit in the foaf:OnlineAccount concept. foaf:page is probably too general. Thoughts?

WikiSysop 14:46, 11 January 2011 (UTC): Do Facebook define their own predicates for this?

Blogs and news feeds

TODO: Needs thinking, too. Does the following look okay?

WikiSysop 14:45, 11 January 2011 (UTC): Not quite. I'm not 100% convinced a news feed and weblog equate, but also foaf:weblog should link to a document (if we care about domains/ranges). We also only talk here about how to /relate/ social media to orgs/people/groups. I think later we might want to explore SIOC, but not today!
